12 | MAY 2023 WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESA farm in the northwest of Kent has significantly enhanced its biogas operation by upgrading the mixing system for its two 1.1-million-gallon anaerobic digesters. Oncoland Farm (part of The Billings Group) had been experiencing problems with the mixers that were installed when the gas-to-grid AD plant was built in 2020 as part of its continuing diversification. Traditionally, a mixed farm of arable, dairy, and beef, Oncoland has successfully added hops, vines, and renewable energy to its portfolio as part of its drive towards Net Zero. However, as Plant Manager Carl Woolley discovered, the mixers that were included as part of the package deal, were unsuitable for the feedstock that combines the farm’s cattle slurry with waste from vegetables grown at the 2,500-acre site, such as cabbage, potatoes, BIOGAS BENEFITS AT THE FARM WITH TOUGH NEW MIXERS Large production requires sturdier equipment BY SOREN RASMUSSEN, LANDIALandia’s POP-I mixers have had an immediate positive effect on the biogas process at the farm.Landia’s POP-I mixers have had an immediate positive effect on the biogas process at the farm.

MAY 2023 | 13WWW.MPTMAG.COMMPTand carrots. Oncoland’s feedstock also includes waste pomegranate and mango that is first sent though a hammer mill.“The mixers would have probably been fine for a standard mix or maize and slurry,” says Woolley, “but for a plant such as ours with varying types of waste, you need much sturdier equipment. Only six months in to us producing biogas, we started to see that the submersible mixers were beginning to fail due to the ingress of water. Although the separate, paddle mixers in the digesters continued to do their job, over time, the submersible mixers, one-by-one, gave up the ghost.”Working closely with James Gorridge at Mid-Kent Electrical Engineering (MKE), Woolley looked at how best to resolve the issue with the submersible mixers and get the plant to its optimum operation.“We weighed up the costs of retrieving the faulty mixers for repair and rewinding,” says Gorridge, “but we both knew how disruptive that would be to the whole process, and the fact that we’d be fixing equipment that was inevitably going to fail again in only a short period of time.”MORE COST-EFFECTIVE AND RELIABLE IN THE LONG TERMWoolley adds, “Removing the submersible mixers would have first involved waiting for dry, calm weather and hiring in a crane. Then, two full days of arduous work and a huge amount of downtime in halting the biogas process, emptying the digesters, and then starting everything up again. We both went away to consider the best, long-term solution. MKE have always supplied us with very good quality motors and drives, with a very good turnaround and attention to detail, so I knew they believed in quality. During my career I’d seen just how robust mixers and pumps are from Landia. And based on his separate previous experience with Landia equipment, James agreed that despite the higher capital investment, their mixers would actually work out to be far more cost-effective and reliable in the long term, significantly reducing our maintenance costs.”At Oncoland, new Landia mixers have saved considerably on energy consumption.

14 | MAY 2023 WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESWhen the four failing submersible mixers were finally removed, it was discovered that their propellers had actually experienced very little wear.“This was because they were the wrong shape and didn’t really do anything,” continues Woolley. “With just a couple of basic seals, they just weren’t designed for this type of biogas application, so had started to let liquid in very early after they were installed.” To optimize the process, Woolley and MKE also saw that the mixers has been underspecified, so chose to go up a mixer size.“We knew this would further improve the mixing, which is crucial for any biogas plant,” adds Gorridge. “It would also have less impact on the new mixers from Landia, which would only have to run for twenty minutes per hour (compared to 24/7 for the failed mixers), saving considerably on energy consumption.”Four of Landia’s POP-I (18.5kW 300 RPM) mixers were installed (two on each digester), with an immediate positive effect on the process, which typically handles dry solids of around 8 percent and higher.COMPREHENSIVE MIXING“Previously,” says Woolley, “it took time for everything in the tanks to get going, but the new Landia mixers resuspended the contents almost immediately. We now get comprehensive mixing and no crust whatsoever. The other important benefit is that the mixers are easy to maintain, especially with their twin-mechanical seals.”In addition to the two primary digesters, Oncoland’s pre-treatment tank (18,000 gallons) has also benefitted from an upgrade to more suitable equipment; this time with a Landia Chopper Pump (invented by the company in 1950).CONSTANTLY CONDITIONED“We took the opportunity to widen our upgrade to the pre-treatment tank,” says Woolley. “Again, the submersible mixer that was supplied as part of the plant package wasn’t up to the job, leaving lumps in the feedstock and dead spots in the tank. But now with the Landia Chopper Pump (11kW), which is extremely reliable, the feedstock of slurry from our dairy unit, plus the vegetable and fruit waste, is constantly conditioned so that our process benefits from a consistent soup. The Chopper Pump’s blades remain fine and sharp.”He adds, “With both the Landia pump and mixers, we now have peace of mind. Working with James at MKE, we saw that we could have bought mixers at around £4K less per unit, but biogas feedstocks are unforgiving. The whole process is about learning and nurturing. There’s just no hiding place for equipment that isn’t sturdy. We bought on reputation and can see already what a sound investment it has been. Biogas is a different beast here in the United Kingdom, so best buy the mixers and pumps that are fit for purpose.” SOREN RASMUSSEN is the director of Landia, Inc.

16 | MAY 2023 WWW.MPTMAG.COMMPTWATER & WASTEWATER FOCUSWATER & WASTEWATER FOCUSMunicipalities must safely clean and maintain many miles of sewer line annually to eliminate blockages and prevent sanitary sewer overflows, which are regulated by the Environmental Protection Agency (EPA). However, the use of high-pressure equipment in underground sewers can be dangerous unless operators are well trained and fully understand the hazards.Understanding and correcting some of the most common operator mistakes in sewer cleaning can go a long way toward keeping them safe. Therefore, safety expert Dan Story, operations manager at KEG Technologies, who has instructed operators for decades, provides ten tried-and-true sewer cleaning safety tips that address the most common errors that he has observed. The Spartanburg, South Carolina-based company is a manufacturer of sewer and storm line products including Tier 1 to Tier 3 nozzles, chain cutters, floor cleaners, and camera nozzle systems.As a national trainer of best-practice techniques, the company is a member of NASSCO, the National Association of Sewer Service Companies, and its Tier 3 High Efficiency nozzles, 10 EXPERT TIPS TO ENSURE SAFE SEWER CLEANINGHow to protect operators from some of the industry’s most common mistakes BY DEL WILLIAMSTier 3 nozzles can deliver safer sewer cleaning at lower PSI.

MAY 2023 | 17WWW.MPTMAG.COMMPTsuch as the Torpedo, Royal, and OMG, provide up to 98 percent efficiency.1 PROPERLY SET UP THE AREA AROUND THE SEWER VACUUM TRUCK TO ENSURE OPERATOR SAFETY IN STREET TRAFFIC“To start sewer cleaning, when you park the vacuum truck in the middle of the road, you need to block off the traffic so it can pass in a safe manner. Set safety cones in front and behind the work zone and make sure the hazard flasher lights are functioning correctly,” says Story.2 KEEP EQUIPMENT NOISE LEVELS LOW ENOUGH TO HEAR TRAFFICRevving the sewer truck engine and running its vacuum pump can be noisy. So, Story advises keeping RPMs low enough so operators can hear and avoid approaching vehicles and converse with co-workers as needed. One way to lower sewer vacuum truck RPMs during engine operation is by only using the vacuum when needed and allowing the water to pass through as the solids remain. “You can put the nozzle in the bottom of the sewer pipe and let the water run around it. The solids remain to vacuum as needed. You do not need to run continuously high RPMs,” says Story.Another method is using more efficient nozzles, which enable sewer cleaning with lower pressure water, reducing engine RPMs.3UNDERSTAND HOW YOUR SPECIFIC SEWER TRUCK BOOM OPERATESThere are differences in how every sewer truck manufacturer configures, deploys, and extends the booms that control the vacuum hose. Some deploy rapidly, some articulate, some telescope. Operators must understand these differences before operating a boom in the field around their co-workers.“Because you may go out in different vehicles from day to day with different crew members, it is important that you understand your boom equipment. For everyone’s safety, do not rush the job because the boom can cause injuries if it is not used with full understanding and control,” says Story.4USE PERSONAL PROTECTIVE EQUIPMENT (PPE) AND PRACTICE GOOD HYGIENE“Protect your hands and feet with waterproof gloves and work boots. Protect your eyes with goggles or a face shield. Of course, protect your head with a hard hat to avoid injury from a swinging boom or a falling object,” says Story. When cleaning sewers, operators exposed to sewage or human waste may be at increased risk of becoming ill from waterborne diseases. To reduce this risk and protect against illness, operators should wash hands with soap and water immediately after cleaning sewers before eating or drinking. Avoid touching the face, mouth, eyes, and nose

18 | MAY 2023 WWW.MPTMAG.COMMPTWATER & WASTEWATER FOCUSWATER & WASTEWATER FOCUSwhile handling sewage, and cover any open cuts, sores, or wounds with clean, dry bandages.In addition, Story points out that the CDC advises vaccination against Hepatitis A and B and other contagious diseases that could put operators at risk when exposed to sewage or human waste. The CDC, in fact, also recommends vaccinations for tetanus, polio, and typhoid fever in these environments. 5 OPEN THE UPSTREAM SEWER MANHOLE FIRSTIn underground sewers, operators can be at risk from toxic inhalation. High concentrations of methane in enclosed areas can lead to hazards as large amounts of methane decrease the amount of oxygen in the air. Oxygen deficiency can cause headache, nausea, dizziness, and even unconsciousness. Story says that one of the first things that operators must do is open the upstream manhole as a precaution to enable drawing in clean air.“For safety in sewer pipe, the first thing you always want to do is open your upstream sewer manhole. That will allow the system to draw in fresh air. On the other hand, if the air were to be drawn directly from the homes, it could fill them with sewer gas, which is unsafe and unpleasant for homeowners,” says Story.6TO AVOID INJURY, DO NOT START HYDRO JETTING OUTSIDE A PIPEWith hydro jetting, sewer cleaning nozzles are designed to direct water at exceedingly high rates of pressure. For typical cleaning, 1,000 to 1,500 PSI is normal. To remove a blockage, pressures as high as 5,000 PSI may be reached.“Sewer cleaning nozzles at extremely high pressures should only be used in a pipe,” cautions Story. “If a nozzle is used outside of a pipe, it can whip around like a fire hose. I have seen sewer nozzles and hose go up and wrap around telephone wires. I have seen nozzles over 60 feet in the air.”7 USE A HOSE WITH A ROBUST SAFETY FACTOR TO PREVENT BURSTINGSince hose and nozzle pressures can be so high, it is important to utilize only robust hose of sufficient strength to ensure safe use over time, according to Story.“Most operators and municipalities overlook the possibility of burst hoses. However, hose is gradually cut going in and out of sewer pipe. The braided nylon weave remains, but every layer that is cut reduces hose strength and the corresponding PSI that can be run,” says Story.8 PROPERLY SIZE THE NOZZLE-TO-HOSE CONNECTION TO PREVENT NOZZLE “RICOCHET”If the nozzle-to-hose connection is not sized properly, it can lead to a dangerous, high-pressure “ricochet,” where the nozzle and hose can suddenly turn around and come back at the operator. One way to prevent nozzle “ricochet” is to size the nozzle-to-hose connection properly, according to Story.“As a rule of thumb, the distance from the tip of the nozzle to where the hose connects needs to be approximately one-and-a-half times the size of the pipe diameter you are cleaning. Sizing it in this way can help to prevent the nozzle from turning around and coming back at you,” he says.He also advises against “free spooling” a nozzle up the sewer line.To prevent free spooling the nozzle up the line and losing control, use a nozzle skid and hold the nozzle back.• Manufacturer of the Muniflo Rotary Lobe Pump (originally manufactured by Wemco since 1985)• We also manufacture aftermarket pump parts for most models of Borger®, Vogelsang®, Lobeline®, Lobeflo® and Muniflo® Pumps• Specialize in Rotary Lobe Pump Repairwww.equipump.com | www.muniflopump.com800-783-5623 | fax 800-693-5623 | info@equipump.comAre you looking for obsolete LobeFlo® (SSP/MGI) pump parts?

MAY 2023 | 19WWW.MPTMAG.COMMPT“Any time you free-spool a nozzle up the line, you lose control of the nozzle—and it can ricochet back at you. To prevent this, use a nozzle skid and hold the nozzle back,” says Story.9 CHOOSE THE RIGHT NOZZLE FOR THE JOB TO REDUCE TURBULENCE AND WEARAs is known throughout the industry, there are several tiers of nozzles, rated for water efficiency from Tier 1 (about 30 percent efficient), Tier 2 (50 to 60 percent efficient), to Tier 3 (75 to 98 percent efficient). What sets the most efficient Tier 3 nozzles apart from others in the category is fluid mechanics engineering on a par with the aerodynamics of race cars or jet fighters. In the case of KEG Technologies’ Tier 3 nozzles, the high-performance fluid mechanics design leaves little room for power losses and excessive turbulence. By more effectively containing, controlling, and directing high-pressure water with less turbulence, a Tier 3 nozzle can deliver more cleaning power at lower PSI. This eliminates the need for operators to compensate for the lack of power from Tier 1 or 2 nozzles by increasing the pressure to higher PSI on the way back through the line. Ultimately, less PSI (with a better, faster result) makes for safer sewer cleaning, as outlined in many of the tips above.10 SLOW AND STEADY WINS THE RACE— AND IS SAFER FOR OPERATORSThe number one mistake of most sewer cleaning operators that puts them at risk is rushing through the process, according to Story.“Most operators run their nozzles way too fast. Rushing to clean more footage of sewer pipe is dangerous. To clean safely, keep the nozzle slow and steady and let it do its job,” says Story.To stay safe and productive, Story advises contractors to never outrun their water, or they risk losing control of the process and will eventually run into a blockage.“Sooner or later operators will run into a blockage of roots, grease, mineral deposits, or cave-ins that will plug up their front jets. Then they no longer have a penetrating tool but a battering ram—a nozzle with no forward jets trying to feed its way through the blockage,” says Story. He advises, “For greater operator safety, slow down even more to remove a blockage and let the nozzle do the work. The reason we put forward jets on the nozzles is to safely open the blockage before the nozzle arrives. Slow down and the water will open the blockage before the nozzle ever gets there.”While there is much more to the practice of sewer cleaning, following these ten tips will go a long way toward keeping operators safe and productive on the job for many years to come. Those seeking a more comprehensive understanding of best-in-industry safety practices can train in person or virtually with KEG Technologies in the timeframe most suitable for them. For safety in sewer pipe, open the upstream sewer manhole first, and this will allow the system to draw in fresh air.DEL WILLIAMS is a technical writer based in Torrance, California. KEG Technologies Inc. is headquartered in Spartanburg, South Carolina. KEG`s patented fluid mechanics directs high pressure water from a truck or jetter hose in a manner so efficiently they were granted a United States patent, meaning operators can usually clean pipes using less pressure, less fuel consumption, and less time than other less efficient nozzles.

20 | MAY 2023 WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYIn the first part of this series, we introduced how the vulnerabilities now exposed within lean manufacturing models are threatening supply chain reliability for various sectors. Below, we begin a run-down of these different threats. First, however, we should provide some general context for how these vulnerabilities are viewed by the industry as a whole. In brief, some key differences between the finding of 2021 and 2022 surveys include the following:1. The results of the 2022 survey show that 70 percent of participants have implemented measures to improve their supply chain resilience, compared to 63 percent in 2021. This indicates that companies are increasingly recognizing the importance of preparing for supply chain disruptions.2. In the 2021 survey, 26.8 percent of respondents considered the pandemic as a major supply chain concern. This number has increased significantly in the 2022 survey, with 57 percent of respondents citing it as the second biggest concern.3. 49.4 percent of respondents reported experiencing more raw material shortages in 2022 compared to 2021.SUPPLY CHAIN RESILIENCEWhat it means and why it matters Part 2 of 3 BY MERRITT GURLEY AND CHANDRAKANT ISI, HUBSwww.mptmag.comSEE •PART ONE•VISIT

MAY 2023 | 21WWW.MPTMAG.COMMPTThe following sections analyze a range of disruptions that were a major concern in 2022.GEOPOLITICAL ISSUESFirst, the Ukraine war brought global supply chain to its knees. In addition to the tragic loss of lives, the ongoing Russia-Ukraine war has significantly impacted global supply chains. The conflict has disrupted essential air freight and shipping routes, leading to disruptions in the supply of raw materials and finished goods. Unsurprisingly, 45.3 percent of businesses reported being impacted by the war in our 2022 survey.The war has far-reaching consequences. In 2020, Russia accounted for approximately 29 percent of crude oil and 43 percent of natural gas imports into the European Union. The fresh round of sanctions against Russia has led to a significant increase in energy costs across Europe. As a result, many metal and chemical factories in Europe went dark in 2022. This aligns with the findings of our survey, where 55 percent of respondents expressed concern about the impact of rising energy costs on their businesses, and 55.6 percent of participants were worried about the impact of these costs on Europe's manufacturing capabilities.Another issue concerns how the United States-China trade war shows no sign of slowing down. The increased tariffs and trade barriers between the United States and China have disrupted the flow of goods and materials between the two countries. This has made it more expensive and difficult for businesses to import and export goods. As a result, many businesses have had to find alternative suppliers or production locations, disrupting their supply chains and increasing their costs. The uncertainty and instability caused by the trade war have also made it harder for businesses to effectively plan and manage their supply chains.In what's now considered a new cold war, the United States recently doubled down on its efforts to deprive China of semiconductor technology. In addition to the organizations, the U.S. government now bars its citizens from supporting the development or production of advanced chips at Chinese facilities.Additionally, the United States saw more worker strikes in the first half of 2022 than in all of 2021. North of the border, Canada was hit by the truckers' protest that impaired the supply chains in the country. Across the pond, U.K. port worker strikes strained the supply chains. Spain also faced supply chain issues driven by truck drivers' strikes. Meanwhile in South Korea, the truckers' protests disrupted production as well as the supply chain.Lastly, rising shipping costs hurt the bottom lines of businesses. The steep rise in shipping costs significantly impacted businesses across the globe. In March 2022, it

22 | MAY 2023 WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYcost an average of nearly $10,000 to ship a 40-foot freight container, almost seven times more than in March 2020.The higher freight costs contribute to the overall cost of goods and materials, making it more difficult for businesses to compete in the global marketplace. The increased shipping costs are an obstacle for businesses looking to access new markets and eat into profits for established businesses, making supply chain management more challenging.NATURAL DISASTERSIn recent decades, the world has faced more frequent and increasingly severe natural disasters. Hurricanes, floods, fires, and droughts have devastated communities and entire ecosystems. They also have a major impact on supply chains. They can halt or slow production, reroute resources, damage vital infrastructure, and more. Natural disasters cannot themselves be prevented, but their impacts can be mitigated through strategic investments and reinforcing supply chains.In the year 2021 alone, 401 natural disasters were recorded globally. In the United States, natural disasters cost the economy to the tune of $145 billion in 2021, making it the third costliest year after 2017 and 2005.In summer 2022, a record-breaking heat wave and drought in China caused disruptions and even closures of shipping routes such as the Yangtze. As a consequence, China experienced an energy crisis. Automakers with facilities in Sichuan—both Toyota and Tesla have operations there—were forced to halt production due to power cuts, causing knock-on effects for the Chinese economy and global automotive supply chains.Cargo shipments along the Rhine, one of Europe's key trade routes, were also slowed due to a drought in summer. Delays caused by the drought are expected to slow Germany's economic growth in 2022 by as much as half a percentage point.In the United States, Hurricane Ian caused over $60 billion in damages and is expected to cut Florida's economic growth in Q3 by three percentage points and two percentage points in South Carolina. Flooding in Southeast Australia in October 2022 is expected to cost the country $5 billion in lost economic activity and drive inflation up by 0.1 percentage points.CYBER SECURITYAs companies become increasingly reliant on digital solutions to accelerate and streamline operations, it becomes more important to invest in robust cybersecurity measures and technologies. Today, cybersecurity threats, such as data breaches and ransomware, pose a real danger to intellectual property (IP) and supply chains. Weak security systems, software vulnerabilities, supplier FIGURE 5: THE RISING NUMBER OF NONECONOMIC DISRUPTIONS

MAY 2023 | 23WWW.MPTMAG.COMMPTfraud, and third-party integrations can lead to financial losses and operational disruptions.In Japan, manufacturers have been the biggest targets for cyberattacks, with data and entire digital systems held for ransom. Toyota was forced to shut down domestic production in Japan after a cyberattack at a major supplier in Q1 2022. The event illustrated how a single supplier undergoing a cyberattack can bring an entire production chain to a standstill.In 2021, IT solutions company Kesaya was the victim of a supply chain ransomware attack, which in turn compromised as many as 1,500 businesses around the globe. In Sweden, 800 Coop grocery stores were forced to close because the attack had shut down their cash register operating systems.Cybercrime reportedly cost the US businesses over $6.9 billion in 2021—an increase of $2.7 billion from 2020. The same year, 62 percent of large enterprises in IT, security, development, and DevOps, reported experiencing a software supply chain cyberattack—and 31 percent reported it having a significant or moderate impact.FIVE SUPPLY CHAINS RISKS TO WATCH As we move through 2023, many of the supply chain challenges experienced in 2022 will likely stick around or even escalate. To make matters trickier, there may be other disruptive events on the horizon. 1. China-Taiwan crisis could worsen the global semiconductor shortageEscalating tensions between China and Taiwan have raised concerns about a military conflict in the region. This could destabilize Asia and have serious consequences for global supply chains. Taiwan is a leading producer of semiconductor chips and disruptions to its production capability could further exacerbate the global chip shortage and impede the production of smartphones, computers, vehicles, and electronic appliances. The involvement of other countries, such as the United States and Japan, could further increase trade tensions with China.2. No swift solution in sight for port congestionGlobal shipping delays initially triggered by the COVID-19 pandemic and subsequently aggravated by the Suez Canal blockage and the invasion of

24 | MAY 2023 WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYUkraine are expected to continue into 2023. Barring any other unpredictable obstructions or major labor disputes, port congestion and the consequential higher shipping rates are expected to improve gradually as early as Q2 2023.3. Inflation can disrupt supply chains by causing uncertainty in demandWith inflation at its highest in three decades and the cost of labor, materials, energy, and transportation rising, supply chain costs are also rising. These higher costs are reflected in commodity prices, and as the cost of living increases the more consumer behaviors and demands change. A rigid supply chain can collapse if it can't adapt to uncertainty in demand. Inflation also comes with other risks, such as labor strikes and a greater chance of bankruptcy, which can disrupt trade networks. 4. Surge of COVID cases in China may hamper manufacturing capabilitiesChina's enduring zero-COVID policy and an increase in outbreaks in various cities led to a number of major lockdowns in 2022, which has impacted supply chains. A lockdown in Zhengzhou in November 2022, where Apple operates its biggest iPhone production facility, caused delays for Apple customers around the world. Although the country's zero-COVID policy is no longer in effect, supply chains are still susceptible to sudden disruptions due to factory closures or capacity reductions.5. New carbon emission regulations may lead to slower movement of goodsNew regulations designed to curb carbon emissions may lead to slowdowns in shipping speeds. As instructed by the International Maritime Organization, cargo ship operators must monitor and decrease emissions in 2023. In order to meet their emission targets, older cargo ships will either have to be upgraded or cruise at 10 percent slower speeds. The decrease in transport speeds is expected to create supply chain lags.A LOOK AHEADIn the conclusion to this series, we’ll explore six industries that will face supply chain disruptions in 2023 as well as a closer examination of the global online manufacturing supply capacity. Finally, we’ll conclude by discussing five solutions for strengthening supply chains in 2023 and in the years ahead.

26 | MAY 2023 WWW.MPTMAG.COMMPTPUMP SOLUTIONSPUMP SOLUTIONSA Peruvian mining company reuses process water as part of their iron ore processing. Until November 2019, however, this was made difficult by the fact that the medium, which is collected in a tank on site, has a very high solids content of 60 to 70 percent. After an attempt to drain the water and remove the sediment in the tank with shovels had failed after four days, the owner decided to purchase a submersible pump with an agitator. The experts at Netzsch Pumps and Systems instead recommended a Netzsch Tornado® T1 rotary lobe pump for pumping the slurry from the tank. This self-priming pump uses the positive displacement principle: Two intermeshing rotors continuously transport the medium from the intake side to the delivery side. The strong suction capability allows the pump to work with a high flow rate and handle a high solids content, while a geared motor with low speed reduces the level of wear. A double mechanical seal and a rotary lobe made of Nitrile rubber minimise the risk of abrasion damage. The Tornado T1 in size XLB- 3/2 was installed on a mobile trolley and placed near the tank in March 2021. The staff were able to move the hose freely inside the tank and the sediment could be removed without any issues.At the deposits on the South coast of Peru, around 330 miles from the capital Lima, the Shougang Hierro Perú S.A. mining company mines iron ore and processes it into different products. In addition to an open pit of around 60 square miles, the complex comprises a processing area in the town of San Nicolás with a crushing plant that reduces the ore by 95 percent as well as a magnetic separation plant, a filter plant, and a pelleting plant. The separating plant further crushes and concentrates the ore with cyclones, magnetic separation, and flotation. This process separates the sterile ore from the iron ore, which is then divided into two different product types: a high-grade iron concentrate for sintering and another that is sent to the pelleting plant after a filtration process.REUSE OF PROCESS WATER AFFECTED BY HIGH SLURRY CONTENTWater is required for many of the mine’s working steps. It comes from a 230 x 60 x 27 feet (l × w × h) process tank, which is fed with the medium from concentrate and tailing thickeners. In addition to the water, slurry with magnesium and iron deposits also accumulates in the tank. The liquid rich in solids is pumped over in the tank to then be used in different processes and locations, such as in the magnet plant. A flocculant is used to recover the slurry from the underflow. The water coming from the overflow carries along solids that have accumulated in the tank over the course of many years. However, the water has to be as clean as possible to be reused in other processes. Due to years of solids accumulation, there are too many coarse particles in the water that prevent using it in the REUSING PROCESS WATER AT A PERUVIAN IRON ORE MINEA robust, low wear rotary lobe pump successfully extracts high solids content slurry BY MONICA MITTERSTEIN, NETZSCHNetzsch recommended a Tornado T1 rotary lobe pump for pumping the slurry from the tank.

MAY 2023 | 27WWW.MPTMAG.COMMPTdownstream processes. This made pumping the fluid so difficulty. The mine owner initially decided to resolve the issue with a plant stop. The water was drained from the tank and the employees tried to remove the slurry layer, which was already up to 16 feet thick, with shovels. This procedure turned out to be very unsatisfactory, though, because the slurry had become extremely compressed and we had to introduce water again to peel it from the surfaces. When the deposits had not been removed after four days, those in charge decided to apply a different method. They were now considering the option of using a submersible pump with an agitator to remove the slurry during ongoing operation without having to stop the plants and to drain the water again.SUBMERSIBLE PUMP NOT AN OPTIMUM SOLUTIONTo procure the required pump, the mine owner contacted Netzsch The Tornado T.Envi rotary lobe pumps are adapted to requirements in environmental and biogas technology with easy maintenance.

PUMP SOLUTIONS Pumps Systems but the experts there advised against a submersible pump Customers often consider a submersible pump to be the right solution for them However in this case such a unit would have had to be very big in order to achieve the required flow rate In addition centrifugal pumps usually run at 3 500 1 800 or 1 200 rpm the high speed and the increased solids content would have caused damage to the internal parts of the pump very quickly If the speed has to be reduced even further for example to an eight pole motor with 950 rpm then these pumps need to be even bigger to maintain the flow rate And the motor gains in size as well Because submersible pumps have to be made of stainless steel the Peruvian mining company would have been faced with very high purchasing costs for this pump In addition to all this this type of agitator pump requested by the mine owner is usually only designed for a solids content of up to 50 percent However the solids content in the application in Peru is 60 to 70 percent which would have made operation difficult including frequent failures TORNADO T1 BETTER SUITED FOR WATER WITH A HIGH SOLIDS CONTENT After a detailed analysis of the problem and the liquid to be pumped Netzsch suggested using a Tornado T1 pump of size XLB 3 2 which offers a number of advantages over the originally selected submersible pump The key benefit is that this model is a self priming displacement pump that can ensure continuous pumping due to its design Two synchronised rotors inside the pump intermesh generating negative pressure at the intake side Versatile innovative high performance Nemo progressing cavity pumps cover diverse applications 28 MAY 2023 that continuously pulls the medium towards the rotary lobes which then transport it to the delivery side This powerful negative suction allows the Tornado T1 to pump almost any type of medium This applies to low viscosity and high viscosity substances as well as to thixotropic or dilatant substances lubricating non lubricating shear sensitive or abrasive media It is therefore ideal for the process water at the mine in Peru and can pump out the medium at a high flow rate despite the high solids content of up to 70 percent The material and design of the T1 are always adapted to the special requirements of the designated medium For viscous and abrasive materials and those containing solids Netzsch offers different rotary lobes with suitable geometries in each case Materials adapted to the medium additionally increase the durability of the rotary lobes as well as their service life Tri lobe helical rotors made of Nitrile are used for the application in Peru to minimise the risk of abrasion damage In addition double cartridge mechanical seals are installed which are not sensitive to the solids in the medium The gear motor of the pump works at a lower speed which also causes less wear Overall this lowers the maintenance costs for the pump significantly TORNADO T1 SUCCESSFULLY PUMPS OUT SLURRY To make handling easier for the mining company s staff the rotary lobe pump was installed on a mobile trolley and equipped with flexible hoses This makes it easier to extract the slurry from the tank through the ten ventilation openings at the top of the tank as well as through the corners The function and capacity of the pump was checked on site in April 2021 For this first test the customer used a six inch hose for intake and delivery However they attached a 5 foot long metal lance to the end of the intake hose which made the hose more difficult to handle The pump was started up and MPT took about seven minutes to transport the water to the agitators While pumping the water with the solids the pump maintained the required flow rate The solids content was 20 percent on average with peaks at 30 percent For the second test the intake hose was replaced with a 4 inch model and a smaller lance was used Another hose supplied water with a pressure of 6 bar to loosen the slurry that had settled fully With the new hose and the improved handling of the smaller lance it was possible to remove the required minimum volume of solids After the successful second test the pump now runs without any problems The hose can be moved through the tank easily extracting the solids The Tornado XLB 3 2 continuously provides the required flow rate without pressure loss After these measures the process water from the tank still has the required quality for being used in the ore processing without any issues MONICA MITTERSTEIN is global manager

30 | MAY 2023 WWW.MPTMAG.COMMPTPUMP SOLUTIONSPUMP SOLUTIONSIn a competitive environment, it is essential that a “live” product like beer reaches the consumer in prime condition in order to retain its flavor and the characteristics that make it unique, just as the brewer intended. The beer also needs to be dispensed at a rate that supports venue business levels, and the skill level of the serving staff behind the bar. To meet the above requirements, one of the most effective methods of packaging beer is in stainless steel or aluminum kegs. Kegs transport and dispense mass quantities of beer without impacting its quality or taste by protecting it from exposure to oxygen and sunlight. Kegs also allow the beer to be dispensed easily and quickly for more fast and efficient service.Because space in the bar is often limited, kegs are normally stored remote from the bar area, so the beer needs to be moved from the cellar or storeroom to the tap on the bar. However, the taste of every beer dispensed from a keg that’s stored remotely can be hit or miss depending on the distance it needs to travel and the temperature at which it has been stored.With so many variables at play, having the right beer dispense system is critical to ensuring the perfect pour—from the barrel to the bar, every time. FROM BARREL TO BARA beer pump application guide BY DAVID ALLEN, XYLEMDID YOU KNOW?Beer has a natural carbonation level that is essential for texture and taste. The point where the pressure on the beer is just enough to keep the carbon dioxide in the beer is called the equilibrium pressure. If the beer is maintained at equilibrium pressure, its texture and taste will be exactly as the brewer intended it to be.

MAY 2023 | 31WWW.MPTMAG.COMMPTPERFECTING THE POURTypically, systems that push beer through dispensing systems are carbon dioxide gas or blended gas assisted, which is why it can be challenging to perfect the pour. To transport the beer from the keg to the bar, gas pressure above the level required to maintain the beer at brewery standard is applied to the top surface of the beer, pushing the beer through the tubing to the bar. Head pressure, as recommended by the brewer, effectively delivers the beer to the glass over short line distances. The further the keg is from the bar, the greater the applied gas pressure needs to be—this means recommended head pressure plus added pressure transports the beer from the keg to the glass. Whenever the head pressure applied to the beer exceeds the equilibrium pressure recommended by the brewer, it is easy for the incorrect pressure to be set. This results in conditions where the pressure is either too high or too low. Over time, excess pressure leads to more carbon dioxide being absorbed by the beer. This is known as over carbonation and has two major drawbacks:• Foaming: Carbon dioxide released on dispense leads to too much foam on the beer head, making it difficult to dispense. • Flavor: Too much foam impacts the texture and taste of the beer, resulting in a negative experience for the consumer. The opposite of over carbonation is under carbonation or flat beer. This occurs when the pressure applied to the keg is too low. In under carbonation conditions, the carbon dioxide gas in the beer escapes in the keg until the equilibrium pressure is reached. The result is a flat beer, which destroys the taste and texture of the beer, spoiling the experience of the end customer.The beer pump was developed to overcome such challenges. Unlike traditional (non-pump) dispense methods, the pressure on the keg remains constant at the equilibrium pressure. Maintaining constant equilibrium pressure on any keg means the taste of the beer remains exactly as the brewer intended and the consumer gets a distinct, satisfying, truly enjoyable glass of beer with every pour.DID YOU KNOW?If every faucet on a bar wastes just one drip tray of beer each day, and that bar or restaurant trades for 312 days in a year, an equivalent of 58.5 gallons (468 pints) of beer are wasted.

32 | MAY 2023 WWW.MPTMAG.COMMPTPUMP SOLUTIONSPUMP SOLUTIONSPUSH AND PULL PUMPINGThe use of beer pumps, particularly in environments where excess top pressure is required to traverse a distance, allows an installer and operator to maintain equilibrium pressure in any given circumstance. There is no need to put extra pressure on the beer to effectively move it through the system. Instead, drive pressure is applied to the pump to move the beer. The drive pressure effectively acts like a car accelerator—the more you put into the pump, the quicker it operates. Beer pumps consist of an air chamber, where the drive pressure comes in, and two wet chambers where the beer passes through. The two wet chambers are separated by seals known as diaphragms. Because of this design, the drive gas never comes into contact with the beer. A special shuttle valve forces the air pressure behind each of the diaphragms in turn, allowing one piston to gently suck the beer in, while the other pushes it out the other side. This push-pull action draws the beer from the keg and gently pushes it through the tubing to the bar. When the dispense tap is opened, pressure in the line drops below the drive pressure in the air chamber so the pump runs, feeding the beer line to the bar. When the faucet is closed, the pressure in the line rises to a point where the beer pump stops. It remains stopped until the faucet is opened again to dispense beer.BENEFITS OF BEER PUMPSFor those in the know, there are several benefits found by using beer pumps—benefits that range from serving quality and storage to adaptability and the bottom line: • Beer is maintained at equilibrium pressure, preventing over carbonation.• Beer can be moved over longer distances, allowing kegs to be stored remotely.• Dispense speed can be adapted to meet business demand and skill level of serving staff.• Dispense speed and presentation is consistent with every pour.• The perfect pour prevents beer wastage, saving money.• Less carbon dioxide is used as the beer pump can be driven using a compressor.TOP TIPA multiple beer faucet system using Flojet G56 Beerjet pumps with the Flojet Line Buddy flow reversal valves allows for multiple lines to be cleaned at one time!

MAY 2023 | 33WWW.MPTMAG.COMMPTSOLUTION SPOTLIGHT: XYLEM FLOJET G56 BEERJETDesigned to take the variability out of beer dispensing systems, Xylem’s Flojet G56 Beerjet pump offers enhanced beer quality—from the top to the bottom of every barrel—without impacting taste. Powered by gas or compressed air, the beer is pushed through the lines to the tap without the gas or air ever coming into contact with the beer. The result? A perfect pour, from the barrel to the bar, every time. Key product features include:• Can traverse up to 800 feet horizontally through a single line.• Can deliver beer neatly over 100 feet vertically through a single line.• Can dispense multiple faucets (up to three) from a single key or keg series, lowering the number of kegs on tap.• Can dispense 300 gallons (2,400 pints) of draft beer per hour.• Has a service life of more than 70,000 gallons (560,000 pints).The Flojet G56 Beerjet pump is also easy to clean and maintain and can be used as a line-cleaning pump. By disconnecting the keg coupler and submerging it in a line cleaning solution, the pump will gently draw the solution in and pump it through the system right through to the faucet. Compatible with the Flojet Line Buddy flow reversal valve, operators can optimize line cleaning processes by running cleaning solutions through the Flojet G56 Beerjet pump in both directions. Running a cleaning solution through a beer system in alternating directions—from the faucet to the tap and back again—has been found to optimize line and pump sanitation. Flow reversal valves are an important accessory in beer pump systems. PUMPING IN ACTIONIn conclusion, let’s do a brief rundown of installation tips before you try out your next perfect pint:1. Clean, dry gasses (carbon dioxide, nitrogen, blended gasses, or compressed air) should be applied at 15-90 PSI for gas inlet operating pressure. Calculations for gas pressure additions are used as a starting point to power the pump. Only the equilibrium pressure specified by the brewer should be maintained on the keg2. For optimal results, beer pumps must be mounted directly inside the cooler or cellar wall. Universal mounting brackets can be used to aid installation3. When using a carbon dioxide or nitrogen exhaust, gas must vent outside of the cooler or cellar into a space that is well ventilated, preventing buildup of carbon dioxide or nitrogen. Always check gas or liquid connections to prevent against gas or beer leaks within the system 4. To improve system efficiency, “Foam On Beer” (FOB) detectors are recommended. Installing FOBs on each beer line stops pumping action when the keg or tank is empty, which also supports key change overs5. For multi-pump installations, incorporating a flow reversal valve will help clean lines in a loop, using the beer pump to drive the cleaning solution through the system rather than needing a separate pump6. When installing the system, it is important to ensure that the dispense rate, which is determined by setting the drive gas pressure on each pump, is set to match the skill level of serving staff 7.

34 | MAY 2023 WWW.MPTMAG.COMMPTMOTOR SOLUTIONSMOTOR SOLUTIONSAmong experts there is increasing consensus that spiking energy prices are likely to linger on for the next few years, at least. While the energy crisis escalated because of the devasting war on European soil, the consequences are felt globally. Across the globe, high inflation has sadly pushed families into economic distress, forced factories to curtail production, and slowed economic growth to the point that several countries are now facing a recession. In Europe, where gas supply is vulnerable because of reliance on Russia, gas rationing and significant risk of blackouts might be the result of power supply shortage and grid instability. What have been the political responses to the energy crisis? Overall, most attention politically has been devoted to supply side measures. In an unexpected positive development, the global energy crisis has triggered unprecedented momentum behind the build-out of renewables. The world is now set to add as much renewable power in the next five years as it did in the past 20 feet. This is indeed encouraging and necessary.But since the build-out of renewables is not a short-term fix, one of the main components in the political response to the crisis has been for governments to increase imports of LNG. This is not a long-term solution since competition to attract LNG will be stronger as Chinese economic activity is likely to pick up again. In addition, most emergency fiscal measures have focused on subsidies, such as income THE WORLD’S LARGEST UNTAPPED RESOURCE: EXCESS HEATAmerican industry is sitting on a potential gold mine Part 1 of 3 BY ASTRID MOZES, DANFOSS

In contrast, measures to reduce energy demand structurally, such as investment incentives or regulations to push for higher efficiency, are almost absent in current crisis policies (Germany being one of the few uplifting exceptions to this).Despite skyrocketing energy prices and unprecedented uncertainty on energy supply, we are far from the average efficiency improvement of 4 percent per annum that is necessary if we are to reach Net Zero emissions. Structural efficiency measures, including regulation to reuse excess heat, are almost absent in the political responses to the crisis. This is the case despite the fact that efficiency measures constitute the fastest and most cost-effective tool to mitigate the energy crisis.Most remarkably, only very few initiatives have pushed for more efficient use of the vast amounts of wasted energy in the form of excess heat.As we will see, every time an engine runs, it generates heat. Industries, wastewater facilities, data centers, supermarkets, metro stations, and commercial buildings all generate large amounts of heat that is currently let out in the air with no efforts to reuse it.WHAT IS EXCESS HEAT?Excess heat, also called surplus heat or waste heat, can be reused through

36 | MAY 2023 WWW.MPTMAG.COMMPTMOTOR SOLUTIONSMOTOR SOLUTIONSexisting and well-proven technologies, most notably heat pumps. Heat pumps are electrically powered devices able to transport heat from one place to another. They can, for example, harness heat from the exhaust fumes of a factory or the heated water from the cooling systems in data centers and circulate it in the heating system of nearby homes.Reusing excess heat will lower costs for consumers. It is much cheaper to reuse energy than it is to buy or produce it. On a societal level, excess heat can replace significant amounts of electricity or gas that are otherwise needed to produce heat. This way, excess heat can help stabilize the future electricity grid. Paraphrasing Amory Lovins, using high value energy carriers like gas or electricity for heating is like “using a chainsaw to cut butter,” as heating can easily be covered by low-value heating sources such as excess heat. Adding to this, in the future energy system, new excess heat sources such as power to X facilities will emerge and grow in number—generating large amounts of excess heat that can be utilized on large scale.Compared to a conventionally decarbonized scenario, a full implementation of technologies that tap into synergies between different sectors and enable a utilization of excess heat has the potential to save tens of billions of dollars per year once fully implemented (in 2050). These savings result from large fuel savings leveraged by interconnecting the heating and cooling sector with other parts of the energy system and more flexibility resulting in the better integration of renewable electricity sources in the wider system.In short, ramping up the use of excess heat will lower overall energy demand, give a productivity boost to the economy, and ease the transition to a green energy system.WASTING HEAT MEANS WASTING MONEYImagine you passed through a building and the floor is full of one-dollar notes. Would you keep walking and go about your day? Surely most people would make a small effort to bend down and collect the money. When it comes to excess heat, this is not happening: We are metaphorically letting the money flow as we make no efforts to reuse excess heat in our buildings and industries.Every time an engine runs, it generates heat. Anyone who has felt the warmth behind their fridge can confirm this. The same is true on a larger scale in supermarkets. Keeping food fresh in cooling displays and freezers generates significant amounts of excess heat. A similar process goes for the cooling of the thousands of data centers that are popping up around the world. This excess heat is currently released into the air without any effort to reuse it. Let us take a closer look at this hidden resource of energy.In general, there is a lack of overall information on the excess heat potential of different areas. However, we do know that currently very little of the existing excess heat both from conventional and unconventional sources is recovered and used in large-scale applications. Some of the best data on overall excess heat sources is made by experts at the University of Aalborg and Halmstad University and covers excess heat from a number of sources in the European Union. EXCESS HEAT BY THE NUMBERSIf nothing else is mentioned, the following estimates are so-called “accessible excess heat,” which means that the numbers consider the practical utilization potentials of the available excess heat. In that sense, the numbers are conservative because they only consider sources located within a few miles of urban district heating areas. As we will see, there are ways to exploit excess heat that do not rely on such networks, for instance on-site heat recovery. In addition, it should be noted that excess heat comes in different temperatures. At higher temperatures, it can often be exploited directly, whereas at lower temperatures, it can be boosted by a heat pump. Therefore, the actual utilization of excess heat potentials also relies to some degree on electricity used by technologies such as heat pumps.When looking at specific cities and regional areas, the numbers are found by using the planning tool, “The European Waste Heat Map.” This tool displays excess heat in the European Union countries and the United Kingdom from both conventional industrial sources and unconventional sources such as metro stations, food production facilities, food retail stores and wastewater treatment plants. The numbers can be considered conservative since the tool displays neither residential and service sector buildings, nor data centers. Moreover, this tool also focuses on sources within a few miles of urban areas, therefore discarding remote locations. Plus, the expansive geographic range provides a corollary for possible approaches to harnessing excess heat within the United States.

MAY 2023 | 37WWW.MPTMAG.COMMPTHeating is one of the largest energy consumers. In Europe, heating accounts for over 50 percent of the annual final energy consumption, and most European heat is still generated using fossil fuel-based sources, almost half of which is natural gas. At the same time, all urban areas in Europe have access to numerous excess heat resources. There is about 2,860 TW hours per year of waste heat accessible in the European Union, much of which could be reused. To put this number into perspective it corresponds almost to the total EU energy demand for heat and hot water in residential and service sector buildings, which is approximately 3,180 TW hours per year in the European Union and United Kingdom.In some countries, the excess heat potential matches the heat demand. In the Netherlands for instance, excess heat amounts to 156 TW hours per year, while the water and space heating demand is only 152 TW hours per year.The picture is similar across the rest of the world. For instance, looking at the industrial sector in Northern China there is around 813 TW hours during heating season alone—imagine what the total amount of excess heat in all sectors in the whole of China then looks like!A LOOK AHEADIn the coming pieces of this series, we’ll explore how excess heat can accelerate decarbonization of the industrial sector. The industrial sector accounts for 39 percent of all global energy-related carbon emissions and is—with its current rate of energy efficiency improvements of 1 percent per annum—not on track to meet the milestones of the Net Zero scenario that would require improvements of 3 percent. However, by the conclusion of this series, we will be able to layout specific example and policy recommendations that can take industry toward a more optimistic and sustainable future.
