A NOTE ON THIS ISSUE:Welcome to August’s edition of MPT! First up, our Case Studies section kicks off with the continuing success story of Lakeside Equipment Corporation’s work in Hawaii (pg. 16). As Marian Widdel illustrates, it takes a lot of hard work and reliable engineering to keep paradise looking no nice.Next, for the professional installer, multiple factors need to be considered before choosing a pump, such as pump type, pump size, total dynamic head, and basin size, to name a few. Franklin Electric’s Jeremiah Brodie weighs in with helpful tips on choosing a pump for a sump and waste-management system (pg. 28). The answer is never one size-ts-all.Finally, even though we’re in the dog days of summer, we’re looking ahead to the fall, which, for our industry, means the kick-off of an impressive round of trade shows and related exhibitions. With that in mind, check out our special section (pg. 12) featuring MPT’s choices for must-see exhibitors at this year’s WEFTEC. You’ll want to block off time in your schedule to visit each one.

The May 2024 poll, called "Public Perceptions of Tap Water," included responses from 2,010 adults served by water utilities in the United States.Seventy percent of respondents said they trust their water utilities "a lot" or "some" for information about their water, with scientists close behind at 68 percent. Local governments (59 percent), state governments (57 percent), and environmental groups (57 percent) rounded out the top five most trusted groups. Water affordability continues to be a big concern among the annual survey's respondents. More than one in three report that they struggle to pay water bills on time. Of those who report struggling to pay their water bills, 83 percent would support a federal assistance program. Nearly 77 percent of respondents overall would support such a program."High quality drinking water is critical for all communities," says David LaFrance, AWWA CEO.

Lakeside Equipment Corporation has completed the commissioning of new screens and grit collectors in Hawaii; continuing its solid relationship with the Pacific island group that goes back almost seventy years.The new equipment for the Ritz-Carlton O‘ahu, Turtle Bay, on Oahu adds another landmark to Lakeside’s near eight-decade portfolio in Hawaii.Designed to remove inorganic solids that can be harmful to downstream equipment, the Lakeside Raptor FalconRake Bar Screen at Turtle Bay benefits from multiple rakes that clean the screen, plus rake teeth that penetrate the bar openings to remove captured material. Meanwhile the Lakeside In-Line Grit Collector (ideal for smaller treatment facilities) is an all-in-one aerated grit chamber that maintains circulation in various flow conditions to prevent lighter organic material from settling.REMARKABLE HISTORYWith a presence on three of the Hawaiian Islands, this latest installation for Lakeside is also the 15th different type of equipment system that is has provided to America’s 50th state.Lakeside’s remarkable history in Hawaii began in 1956 when (known as Lakeside Engineering), the company’s visionary president, Dr. John Montgomery, together with his wife, Mary, took the then, epic journey from Chicago to Honolulu, because he firmly believed that good opportunities existed there for the business. He was right. It’s not quite clear whether the Montgomerys took time out to surf and relax on Waikiki Beach, but even if they did, they succeeded in securing their first order on the islands, for a filter, a final clarifier, and a Spiragester at Kailua Heights on the northwest of the Big Island.16 | AUGUST 2024 WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESLakeside has been supplying wastewater treatment equipment to Hawaii since 1956.Lakeside’s latest installation in Hawaii includes a Raptor FalconRake Bar Screen and an In-Line Grit Collector.CLEANING UP GRIT IN PARADISEThe Lakeside success story continues in Hawaii BY MARIAN WIDDEL, LAKESIDE EQUIPMENT CORPORATION

AUGUST 2024 | 17WWW.MPTMAG.COMMPTKnown for always backing its customers with exemplary aftersales service, Lakeside’s Dr Montgomery journeyed all the way back to the Kailua Heights WWTP a year later to check that the operators on site were happy with what had been installed.The next installation in the Pacific for Lakeside was on the island of Kauai, where it installed the first of several low-maintenance, non-clogging open screw pumps, which lift large quantities of wastewater at low heads.HARD WORK AND ENTERPRISELakeside is immensely proud of its long track-record in Hawaii; with this latest order bringing another important, long-term and highly cost-effective solution to Oahu. It is incredible to think that thanks to the hard work and enterprise shown by the late, great Dr. Montgomery, the first equipment for Hawaii was installed sixty-eight years ago—and that the company continues to supply the islands to this very day.Promark Corporation of Kapolei play a pivotal role in Hawaii as the Lakeside sales representative, with their first-class knowledge of their customer’s wastewater needs—and Lakeside’s very popular former vice president, Warren Kersten (now retired) was also instrumental in maintaining and increasing our equipment sales to the islands.In this partnership, Lakeside has built a relationship that has stood the test of time with no end in sight—or, as the locals say, “a hui hou.” MARIAN WIDDEL is administrative manager at Lakeside Equipment Corporation. Lakeside Equipment Corporation is an engineering and manufacturing company concentrating on helping to improve the quality of our water resources.

18 | AUGUST 2024 WWW.MPTMAG.COMMPTSEATTLE PROJECT ADJUSTS TO CHANGING COMMUNITYMore multifamily homes plays role in pump station retrot BY THOMAS RENNERCASE STUDIESCASE STUDIESAthirty-seven-unit condominium project celebrated its grand opening last year along Seattle’s Alki waterfront, bringing a resort lifestyle to residents of the units. In a nation in which many people covet residential spaces on shorelines, it illustrates a dynamic that is playing out in other sections of the United States.The project was developed by Vibrant Cities, which builds multifamily properties in Seattle and Portland. The buildings are “strategically positioned in sought-after neighborhoods and are purposefully designed with building community in mind,’’ according to the Vibrant Cities website. The Seattle project broke ground in 2019 and was the largest condo project planned for West Seattle in 2020. It took Vibrant Cities and a previous property owner twenty-three years to assemble five waterfront parcels for the project. Development is nothing new along Alki Beach, which overlooks Puget Sound and offers scintillating views of Seattle’s skyline. Many of the area’s single-family homes have been replaced with multi-family residences. Such transformations, however, can result in unintended consequences. The Alki Pump Station, which was built in 1959, had reached the end of its useful life. But the area’s population growth and addition of multi-family housing also played a role in the plan by Seattle Public Utilities to renovate the station, which is essential for moving sewage and storm water from the surrounding area to a water treatment facility. More homes mean a city’s infrastructure grid needs major updating, and many U.S. cities have had to adapt to the change. The renovated pump station opened last year, and Seattle Public Works converted the airlift style facility to one that uses centrifugal

Page 23

AUGUST 2024 | 19WWW.MPTMAG.COMMPTpumps. SPW also incorporated art into the project. Using a variety of materials and textures, artist Sarah Thompson Moore created “Tracing Alki.” While a project very much a part of Seattle’s present and future, it also honors the region’s past. “This project seized an opportunity to turn an otherwise unremarkable space into one that the public can truly appreciate, and it invites the public to better understand our wastewater system and our connection with the surrounding water bodies,’’ says Avery Reger, P.E. of SPU.SYSTEM CONVERSIONIn 2015, Seattle evaluated all thirteen of its airlift-type wastewater pump stations. Each evaluation looked at several factors such as parcels served, flow projects, and options for improvement. The Alki pump station was recommended as the highest priority for retrofitting. “Airlift pumps were installed primarily due to solids (in the pumped liquid) that tend to plug and wear out other types of wastewater pumps,” according to an SPU report. “However, these airlift pumps are obsolete and deteriorated—demanding frequent maintenance and subject to availability of replacement parts and equipment.”In addition, Reger says centrifugal pumps have become the norm for moving wastewater. “Increased electrical and hydraulic efficiency and ease of maintenance are just some of the benefits of electrically driven centrifugal pumps,’’ he says. The retrofit required dismantling and removing the existing airlift system. Crews also converted the existing structure into a separated wet well and dry wall configuration.Workers also replaced the 8-inch diameter force main with a 6-inch diameter force main; upgraded electrical and structural components and installed underground ventilation ducting, ducting and irrigation pipe. SPU also added a safety guardrail along a seawall to protect the site. SPU estimated the cost of the project at $1.2 million. Seattle Public Utilities completed construction of the Alki Pump Station in November. (Photo credit: Seattle Public Utilities)ALKI PUMP STATION FACTS & FIGURESWhat:Seattle Public Utilities constructed a new pump station, converting an airlift-style pump station to a more standard station. The conversion will reduce the risk of failure, improve system reliability and performance and reduce maintenance costs. Construction began in July 2022 and was completed in November 2023.Why:The existing pump station, built in 1959 had reached the end of its useful life. In addition, the community had transformed from a region of mostly single-family homes to multi-family residential buildings.Unusual Art:The station includes a 1,200 square feet piece of artwork created by Sarah Thompson Moore. Called Tracing Alki, the work incorporates the natural history of the area before European settlement and was created to interact with the natural environment. Open the Door:Some areas of Moore’s work is included on two floor doors manufactured by BILCO. The doors are equipped with AASHTO H-20 wheel-loading and a pan-type cover that can accept a variety of floor materials.Did you know?The project involved the interests of multiple stakeholders, including the Muckleshoot Indian Tribe. The tribe’s ancestors were among the first settlers in the Puget Sound region.

Page 24

20 | AUGUST 2024 WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESThe conversion will reduce the risk of failure, improve system reliability and performance, and reduce maintenance costs. “The goal of the project was to improve the performance and reliability of the facility while also bringing it up to modern construction codes,’’ Reger says.WORK OF ARTFrom the project’s inception, artwork was planned to be incorporated into the project. “Site improvements would include a concrete pad with public art, a protective guardrail atop the adjacent seawall, and landscape plantings featuring plants native to the Seattle area,’’ SPU says in its proposal. Thompson Moore was selected to develop the project. Her work was inspired by a topographical map of Seattle printed in 1894 and took four years to create.“Through the use of iridescent and light refractive materials and a variety of textures, the artwork was created to interact with the natural environment, offering a unique experience with each visit,’’ Moore writes on her website. Moore said the project incorporates the natural history of the area before European settlement, bringing to light the changes that have occurred since then. She took into the account the interests of various stakeholders, including the Muckleshoot Indian Tribe, whose forefathers inhabited the region for centuries before non-Indian settlement.Determining how to incorporate Moore’s work into the site was logistically challenging. “One major complexity of construction involved the installation of the tile artwork,’’ Reger says. “The tiles needed to be installed integrally with the freshly poured concrete. The process started with the artist loosely gluing the intricate design of tens of thousands of tiles on a fabric scrim at their studio.”The project covers 1,200 square feet, and the area was divided into manageably sized panels while concrete was poured and tooled. CREATIVE SOLUTIONSome of the tiles were placed on two floor doors manufactured by BILCO, the manufacturer of specialty access products. One door was a 5-foot x 5-foot double leaf door, and the other was a single leaf door that measured 3-feet, 3-inches by 3-feet, 9-inches.The doors are also equipped with a pan-type cover that can accept a variety of flooring materials. The cover is designed with a 1-inch fillable pan for field installation of architectural flooring material. The doors allow access to equipment for repair and replacement of parts.The doors are equipped with AASHTO H-20 wheel-loading, which allows for truck axle loading of 32,000 pounds.In most instances, the BILCO terrazzo doors are used for interior applications. It’s also uncommon for doors with the pan design to be included on H-20 doors. Harbor Pacific Contractors procured the doors for the project from Anderson Specialties, BILCO’s manufacturer’s representative in Seattle. “BILCO hatches were submitted by contractor and met the design requirements,’’ Reger says. “There were limited manufacturers that could produce a hatch with an inlay pan for the concrete and tile artwork that was to be installed. Being able to extend the artwork on to the hatches was important for the artist’s vision and hides them in plain sight without affecting the accessibility of the station.”SPU held an outreach event in December 2023 and Reger said the community has embraced the project, which is located in an area popular for walkers, runners, nearby residents out for a stroll with their pets and other recreational pursuits.“The feedback from the community was very positive,’’ Reger says. “Many people praised the thought-provoking, highly detailed artwork and had an appreciation for the dedication and effort of everyone involved to deliver a unique and enjoyable space.” THOMAS RENNER writes on building, engineering and other trade industry topics for publications throughout the United States. The BILCO Company has served the building industry since 1926. During these years it has built a reputation among architects, engineers, specifiers, and the construction trades for dependability and for products that are unequaled in design and workmanship.

AUGUST 2024 | 23WWW.MPTMAG.COMMPTfaster, more efficient method. Plant operators need to consider the cost savings available from shorter washout times, as well as additional profits that can be generated from greater driver availability, and even the potential for additional work. For many concrete plants, the financial benefits of faster washouts can be surprisingly substantial. Some calculation tools indicate that total savings and increased revenue from faster washouts can approach $500,000 annually, or even into seven figures, depending on the size of the operation. Even small operators can achieve savings in the hundreds of thousands of dollars each year. HIGH SPEED WASHOUT EQUIPMENT RECLAIMS TIME, MONEY, AND MATERIALSAfter each delivery, washing out trucks and equipment is essential to meet mix specifications, reclaim unused materials, and keep equipment clean. Ideally, washouts should be fast and efficient, and reclaim all reusable materials.The traditional washout process typically requires drivers to travel to designated washout ponds or pits, sometimes long distances from the plant, to perform washouts. Drivers then manually clean and rinse the truck and discharge the water and concrete into the pit. They then drive back to the plant for the next load. This process can be time consuming and costly. At some plants, specialized washout equipment is used but the process is often still slow due to the fact that the equipment being used requires concrete to be fed in at a slow rate, again, wasting time. Today, a much faster, more efficient washout approach is now being utilized. A high speed, self-contained, closed-loop, concrete reclamation and water handling system that can be conveniently located at the plant.“To perform a washout, the driver backs up to the machine, adds recycled water to the drum, and after mixing, empties the water and concrete into the machine. The system can take eight cubic yards in four minutes, saving producers a significant amount of time.” says Shane Schmutzler, president of Port Washington, Wisconsin-based Jadair International, Inc., a manufacturer of concrete reclaiming and washout systems including the Redi-Claim and Redi-Wash Washout Systems.He explains that these high-speed washout systems are designed to quickly washout trucks and reclaim the materials. Additionally, the Redi-Wash Washout System clarifies the washout internally, without the use of settling pits or presses. The water is then reused for future washouts. The used cement is discharged separately and can be handled easily by a loader as a dry, clay-like product, reducing mess and saving time. To help concrete plant executives estimate the potential savings from using a more streamlined washout

Page 28

24 | AUGUST 2024 WWW.MPTMAG.COMMPTWATER & WASTEWATER FOCUSWATER & WASTEWATER FOCUSapproach, Jadair offers a savings calculator that evaluates factors such as labor, truck costs, and materials. By inserting these values into the calculator, along with the plant operating hours, the calculator provides insight into the potential savings available from a high speed, automated, washout system when compared to their existing washout method.With decades of concrete industry experience, Schmutzler offers some illustrative examples of the potential savings for concrete plant executives:TRUCK AND DRIVER TIME DOWN, ANNUAL SAVINGS UPUsing a high speed, automated, closed-loop concrete reclamation and water handling unit like Jadair’s Redi-Wash Washout System, plants can save as much as $195,000 per year, or more, in mixer truck and driver-related costs.This figure is derived from an example of a ready-mixed concrete plant with 20 mixer trucks, each washing out twice a day. That equals forty washouts total per day at the plant. With the current washout process, it takes twenty minutes for each driver to washout, including travel to and from the washout pit. Using these figures, the total time taken each day for washouts at this plant is 800 minutes.In contrast, a high-speed concrete reclamation system can reduce that time significantly. If, with such a system, drivers can now washout in five minutes instead of twenty, then washouts at the plant will only require a total of 200 minutes per day. This puts the total amount of time saved at the plant at 600 minutes per day. A significant number.If the cost to run a mixer truck is $76/hour, or $1.25/minute, including the driver’s wage, fuel, insurance, etc., this time savings translates into $750/day ($1.25/minute x 600 minutes), for a total of $195,000 per year (260 workdays/year).This savings is realized by being able to deliver the same amount of concrete each day, with fewer mixer trucks and drivers. The savings calculator available from Jadair details these savings in terms of dollars, as well as in terms of how many fewer trucks can be used at the plant to deliver concrete.ADDITIONAL DELIVERIES MEAN ADDED REVENUEWith high-speed washout equipment, the plant can deliver the same amount of concrete it currently does while using fewer trucks, thereby saving money. Or, if market conditions permit, plant operators may choose to keep the same number of trucks they currently have, and use the saved time to make extra deliveries, thereby increasing plant revenue. This can be an attractive option.As an illustration, if the above plant runs ten hours per day, the 600 minutes saved in the previous example is the equivalent of one full workday for one truck and driver. If the plant utilizes this saved time to make extra deliveries, the daily revenue increase could be $3,120.00/day. This is calculated based on the truck delivering an average of four loads/day with an average load size of 6 cubic yards and an average concrete sales price of $130.00/yard. This translates into $811,200/year of additional revenue. Again, a significant number.“Many ready-mix plants find they can significantly improve operations by using a more efficient concrete washout method. The boost to the bottom line can be even greater if plants make additional deliveries with the extra time freed up from shorter washouts,” says Schmutzler.RECLAIMED MATERIALS MEANS EVEN MORE SAVINGS Today, the most advanced high speed washout systems can recover sand and stone for re-sale or re-use, using recycled water in a closed-loop process. This is more environmentally friendly and offers concrete executives the option to sell materials they may have previously paid to haul away. While reclaimed material is not always suitable for high-spec concrete jobs, it can typically be used in lower-spec mixes such as foundations or used as base material.“The [concrete reclamation] system separates the clays and cements from the sand and gravel. We could have New high-speed washout systems present a game-changing solution for fast results.

The ready-mixed concrete plant in the example might average 20 cubic yards of returned concrete daily for a total savings of $2,500 per week, or $130,000 per year in reclaimed materials.ADDITIONAL SAVINGS IN MAINTENANCEIn washout ponds and pits, the cost to replace make-up water, which is often purchased from a local utility or pumped from wells, can add up quickly. “We were using metered city water and had to pay for any wasted water,” says Gelewski.Pond maintenance can also be an issue. Ponds and pits require continual maintenance to remain functional. Ponds need perpetual sludge cleanup and torn pond liners need to be repaired or replaced. Pits fill up with washout material, which must then be excavated and hauled away at additional cost.“About every three months we had to excavate the pit [of washout material], put it in a stockpile, and let it dry out. The material was mixed with clays, fines, stone, and hydrated cement. It was basically a useless product, so we had to pay to have it hauled away to a concrete recycling facility about 12 miles away. At the time, it cost about $200 a load to dump the material, not counting the truck rental; today, it would cost about $500 a load,” says Gelewski.New washout systems offering potential savings and additional revenue to concrete producers.

There is no running back and forth from one site to another, so we are saving a significant amount of time compared to the previous washout pit,” says Gelewski.Since the self-contained, closed-loop, concrete reclamation and water handling system reuses the water, this reduces the need for make-up water typically lost in ponds or pits.“Our water usage is way down because we are reusing it. We are not wasting water to wash out the trucks only to have it evaporate or hydrate into the ground,” says Gelewski,Additional savings accrue from eliminating any haul away and disposal fees for unusable materials, which must be excavated and removed from washout pits as part of routine maintenance.“Now, we no longer need to have a washout pit or a pile of excess material on the side that we have to pay to truck out,” says Gelewski.SEVEN-FIGURE HIGH SPEED WASHOUT SAVINGS POSSIBLEWhen concrete plant executives add up the potential annual savings in truck and driver-related expenses, washout pit maintenance costs, reclaimed material, and the opportunity for increased revenue from extra deliveries, the boost to the bottom line by switching to high speed, automated washout equipment can often total six or even seven figures.“Altogether we are saving hundreds of thousands of dollars a year in driver’s time, truck time, and trucking material using a modern washout system,” says Gelewski.

28 | AUGUST 2024 WWW.MPTMAG.COMMPTWATER & WASTEWATER FOCUSWATER & WASTEWATER FOCUSFor the professional installer, multiple factors need to be considered before choosing a pump, such as pump type, pump size, total dynamic head, and basin size, to name a few. If the homeowner has a high groundwater level and is prone to flooding due to spring thaw or heavy rain falls, you may want to consider a sump pump sized for higher flow or head pressure to move that water away from your home and valuables. Also, if your customer has an older home and a smaller basin, you may want to consider a pump with a diaphragm switch with no moving parts.Read below to get additional details on three standard pumps found in residential properties in North America—and which one might be the right one for your job.SUMP PUMPSA sump pump removes standing water from the sump basin in a basement or crawlspace. A sump pump can also be used in other applications such as general dewatering, storm shelters, and emergency water transfer. Select sump and light effluent pumps can handle solids half inch or less, depending on the application.For example, if you have a sump basin that has a gravel base you may run into small rocks or debris that may be loose and may be moved through the pump and out the discharge. With a sump/light effluent pump anything under a half inch will move down the line easily. Here are a few tips on selecting the best sump pump for your application:PUMP CONSTRUCTION Cast iron is one of the most robust materials for a sump pump housing. Cast iron is strong and corrosion resistant. Remember that cast iron, unlike other sump pump housings made of steel or cast aluminum, dissipates heat more effectively. To increase the longevity of the electric motor, it is better to keep it cooler. Cast iron will pull the heat away from the motor more efficiently. Another option for brackish water applications is a bronze pump housing. Bronze will withstand brackish applications more so TIPS FOR SELECTING THE CORRECT PUMP FOR YOUR INSTALLATIONChoosing a pump for a sump and waste-management system is never one size fits all BY JEREMIAH BRODIE, FRANKLIN ELECTRIC

Page 33

AUGUST 2024 | 29WWW.MPTMAG.COMMPTthan cast iron, cast aluminum, steel, or thermoplastic.SOLIDS HANDLING CAPABILITIESA non-solid handling sump pump could clog the volute and prevent water from passing. At that point, the water in the basin will continue to rise and potentially cause damage to your home and valuables. If solids in the sump basin could pass through the sump pump, a semi-solid sump/light effluent pump should be considered. A sump/effluent pump with a half inch or less solids handling capability is recommended in this situation. There are also sump pumps with a screen on the bottom of the volute for nonsolid applications.SWITCH TYPE There are multiple switch options offered for sump applications. The most common sump pump switches are integral snap-action float switches, tethered float switches, and diaphragm (atmospheric pressure) switches. Diaphragm switches are ideal for basins that include a primary sump pump and a battery backup system since no moving parts exist. Integral snap-action float switches are suitable for smaller-diameter sump basins since the switch moves vertically up and down. Tethered float switches may take up more room to allow the switch to swing out and turn on. Tethered float switches remain extremely popular in the industry for specific applications.EFFLUENT PUMPSEffluent pumps are used to move sewage gray water from one location to another. This pump type is most used in a septic system with an effluent chamber and drain field or mound system but can also be used for other situations that may need a pump for three-fourth inch solid handling capabilities. The capabilities of an effluent pump are not limited to one application. Septic systems are the primary use case scenario for effluent pumps. Other areas we see these pumps used are for dewatering flooded loading docks and in the removal of water in elevator shafts. These pumps range in performance from high head to high flow applications. Here are a few tips to help you select the right effluent pump for your next jobsite:PUMP SIZE AND SWITCH TYPE Keep in mind total displacement head and the flow your job requires. Also, the most popular switch types for effluent pumps are tethered mechanical float switches, integral snap-action float switches, integral vertical float switches, and control panel operation with a manual pump.PUMP CONSTRUCTION AND DURABILITYThe environment surrounding an effluent pump can be harsh. Make sure the pump you are using is up to the task. Cast iron housing construction will provide the durability to pump effluent gray

Page 34

30 | AUGUST 2024 WWW.MPTMAG.COMMPTWATER & WASTEWATER FOCUSWATER & WASTEWATER FOCUSwater. In some applications, a cast iron impeller is another added durability option in harsh conditions.SEWAGE PUMPSLike effluent pumps, sewage pumps are used to move sewage from one place to another. Unlike effluent pumps, sewage pumps are used to move solids up to two inches in diameter. Sewage pumps are used in residential, industrial, or light commercial ejector applications, such as a below-grade bathroom where gravity cannot be used to move sewage to a septic tank or the city main.Also, if you have applications where your sewage ejector is prone to clogging or binding from flushable wipes, rags, or any other objects that may not pass through the ejectors impellers, a grinder pump may be the solution for your system.PUMP SIZE Total displacement head, flow, and shut-off head are critical factors in how far your sewage ejector will move waste. Also, when selecting a sewage pump, consider how many water fixture units (toilets, sinks, etc.) produce waste that will be feeding the wastewater system. These pumps range in horsepower from 4/10 to vast horsepower offerings depending on residential, municipal, and industrial applications. Households with four or more residents may require up to a 2 horsepower sewage pump.IMPELLER DESIGNVortex and non-clog impellers are common choices when choosing a sewage pump. Depending on TDH and flow, the end-user has options when selecting the correct pump for the job.BASIN SIZEFor a typical residential installation, a minimum of an 18x30 inch basin is adequate. For systems requiring two sewage pumps (duplex systems), they will require a larger basin (a minimum of a 30-inch basin is suggested).CHOOSE THE RIGHT PUMPWhen evaluating the best pump for the job, performance curves can help you determine what type of pump will deliver the maximum amount of efficient pumping. Performance curves show the capacity of wastewater for which the pump can move. When selecting a pump, choose one that will operate in the middle of the curve for optimal performance.Remember to ask yourself key qualifying questions when choosing the correct pump for the job. What type of pump is required? What liquid is being pumped? Does the liquid have solids? What is the performance needed of this pump? How many pumps will be in the basin? Answering these questions will ensure you choose the right pump for your application. JEREMIAH BRODIE is a business unit trainer for the Little Giant brand of Franklin Electric.

32 | AUGUST 2024 WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYEven the smallest municipalities are benefiting from advanced automated water monitoring and analytics systems and a boost from AI is right around the corner. SMALL TOWN, BIG TASKWith a population of approximately 352, the town of Abbott, Texas, is small, even when one considers that the average local jurisdiction population in the United States is only about 6,200. Regardless of its size, one thing that Abbott has in common with all other municipalities across the nation is the reality of maintaining its infrastructure on a finite budget.When city officials were examining options for reducing costs by automatically monitoring the town’s drinking water system, it quickly became clear that a full-blown supervisory control and data acquisition (SCADA) system was not in the budget. However, Cattron, a company specializing in control and automation systems, had an alternative solution that could offer much of the functionality of a full SCADA system at a fraction of the cost.REMOTE CONTROLThe company suggested the Abbott team explore Cattron’s RemoteIQ Water, a purpose-designed system. RemoteIQ Water is an advanced cloud platform designed for the monitoring and control of applications like lift stations and water treatment plants. It delivers unmatched convenience and reliability without the high costs and complexities associated with implementing a full-scale SCADA system.With RemoteIQ Water, operators can remotely monitor performance, receive alarms, and manage remote assets such as tank levels, line pressure, flow rates, and water quality from any location, using mobile devices, tablets, or laptops.

Additionally, with fifty-eight Modbus RTU channels, the system seamlessly integrates with existing PLCs or Modbus sensors, enabling smooth data exchange and control.“We were looking for a cost effective and reliable way to remotely monitor our water supply system,” explains Tony Pustejovsky, mayor of Abbott Texas. “Our systems integrator recommended the Aquavx product.” GAINING AN ADVANTAGESince the implementation of Cattron’s RemoteIQ Water platform and Aquavx remote monitoring device, the town of Abbott has experienced significant improvements in the efficiency and management of its drinking water system. The six pumps, located at two water wells, are now monitored continuously, ensuring optimal performance and load sharing.The RemoteIQ Water platform allows city officials to track pump cycles and run times, setting up alarms and alerts if any out-of-balance operation occurs. This proactive approach enables the town to address potential issues before they escalate, extending the life of the pumps and minimizing the risk of system failures. With 24/7 monitoring and alert notifications, Abbott’s water management folks can respond swiftly to any issues that arise. The ability to remotely control and override the automatic control of the pumps from a smart phone or tablet has been a game-changer, allowing the team to take immediate action when needed, without having to be on-site. This has greatly contributed to the overall efficiency of the system, preventing overflows and ensuring the water system remains uncontaminated.The continuous statistics provided by the RemoteIQ Water platform on pump duty cycles and runtimes have also enabled the town to perform predictive analytics and schedule maintenance activities proactively. By monitoring the pump run times, the team can identify when a pump is due for servicing, reducing unexpected downtime and costly repairs. Additionally, the system alerts the team when duty cycles become unbalanced by a certain percentage, indicating the need for preventative maintenance.“The ability to monitor, control, and maintain our system remotely from anywhere was a very attractive feature,” says Mayor Pustejovsky. “I’m optimistic that the city will benefit from additional efficiencies and increased uptime of all of the systems that supply water to our great community.”Cattron’s RemoteIQ Water is a cutting-edge cloud platform that offers unparalleled convenience and reliability without the cost and complexity of implementing a full-scale SCADA system.Real-time data and insights are powered by the RemoteIQ Water cloud platform, and are available to Abbott 24/7.

AUGUST 2024 | 37WWW.MPTMAG.COMMPTDESIGN IS FUNDAMENTAL TOCONTROLLING COSTSTable 1 is a summary of the wide variety of potential wastewater treatment plant pump applications. Picking the right design for the specific application is critical for ensuring the pump (and the overall system) is going to operate properly. This will in turn be the major influence on the overall cost of ownership (COO). Much of the cost is determined by the initial system design and pump technology selected. A common rule of thumb suggests that about 80 percent of overall equipment life costs (maintenance, operation, and Energy consumption) has to do with the initial design of the overall plant and process equipment/pumps used. In other words, whatever is designed comes with a set amount of fixed costs. Therefore, selecting the right equipment (in terms of size, technology, and options/features) will have a major effect on costs; selecting the wrong equipment will result in higher costs and more downtime. Another 10 percent goes to environmental costs (disposal), installation, and downtime. This leaves approximately 10 percent for the initial purchase of the pump. There are several progressing cavity (PC) pump configurations that can be used for these applications. Each has advantages and disadvantages, and some are more appropriate than others for a particular application. PC pumps can run a long time without service, but when needed, the service required can depend on the design and options selected for the pump. Joints, access windows, type of seal, stator design, rotor materials and coatings, bearings, and ancillary equipment around the pump impact service. Ultimately the pump needs to be designed for minimal and easy servicing. When one examines the total cost of ownership, including the initial cost of purchase, the electricity used, parts, and maintenance, what looks like a lower cost option may actually end up being the higher cost option. Reduction of service frequency, reduction of required pump parts, and easier, faster serviceability are critical attributes for pump selection. Focusing on these particular areas and spending a little bit more money upfront, will pay dividends.PUMP DESIGN CONSIDERATIONSMost operators will work in collaboration with an engineering firm to select and size the right equipment. Keeping in mind that the correct design is important for reducing costs, operators should consider the following factors when selecting a PC pump. Each one has its own positive and negative impact. Speed The faster you run the pump, the faster it will wear and the more frequently service will be needed. In other words, greater speed = exponential wear. However, a fast pump usually means a smaller footprint and lower upfront cost (but you pay on the back end with more repairs). Slower is usually better for most applications. Drive Configuration The key issue is how much space is available for the pump. PC pumps are long in nature. Adding a bearing frame adds more length, but provides a robust drive shaft supported by independent bearings to handle the thrust load of the pump. This is the force (axial load) pushing the opposite direction from flow across the centerline of the pump. This is essentially what the pump undergoes as it pumps against the system backpressure. Whereas the direct drive is shorter and for low pressure and is sufficient for many applications. Typically bearing frames are used when the need for high pressures exceeds direct drive capabilities, when the desire for easier servicing is required, or when a belt configuration for space restraints is preferred. Piggyback/overhead or L-shaped bases can shorten the installation footprint. Vertical mounting of the pump can also accommodate limited space.TABLE 1 - WASTEWATER TREATMENT PLANT PROGRESSING CAVITY PUMP APPLICATIONSPump stationsRaw sewage, wastewaterPrimary and secondary sludgeReturn activated sludge (RAS)/waste activated sludge (WAS)/thickened waste activated sludge (TWAS)Heat exchangers, digested sludgeSludge dewatering feedLime/carbon slurryChemical transfer and meteringpolymers, flocculants, and precipitantsFOG (fats, oils, grease) receivingSeptage/sludge receivingDissolved air flotation (DAF), scumBiogas, biomass, anaerobic/aerobic digestionSludge cake, dewatered sludgeFigure 2: iFD-Stator® 2.0.

Page 42

38 | AUGUST 2024 WWW.MPTMAG.COMMPTPUMP SOLUTIONSPUMP SOLUTIONSViscosity The thickness of fluid limits the pump speed, suction, discharge piping ID, and pipe length from the pump by significantly influencing the design and the pressure losses of the system. This affects the suction side or the NPSHa (net positive suction head available) for the pump. Pumps have a specific amount of head pressure required to operate correctly. Otherwise, the result is cavitation and potential failures.Pump Rotor and Stator Geometry For the most part, two geometries dominate the various applications. For simplicity’s sake, we will call them low flow/high pressure and low pressure/high flow. Both have their own inherent ratings for NPSHr (net positive suction head required) based on the pump's internal design. There are other geometries that can provide higher flow at higher pressures and another for higher flow at lower pressures. Typically, you trade off flow for pressure and vice versa.Number of Stages The maximum discharge pressure and ultimately the pump rating per stage is determined by the number of stages. Typically, each stage is rated for 90 psi (6 bar). Therefore, two stages would be rated for 180 psi (12 bar) and so on. Adding more stages for a given rated pressure divides the pressure affecting each stage. More stages equals lower pressure per stage and allows for longer life. With most applications in WWTPs, there is abrasion. Abrasion comes from grit and other inorganics (as well as some organics), that cause wear over time on the pumping elements. This wear is to be expected; it is normal to de-rate the pressure per stage due to the amount of anticipated wear. For example, pumping polymer is very lubricating, has no abrasion factor, and can be rated for the maximum capability of the pump. As another example, 1-2 percent sludge may only be derated by 20 percent per stage (90 psi x 80 percent = ~70 psi) making the rated discharge pressure 70 psi or less. Finally, if you were to pump cake (20 percent or higher), each stage would need to be derated to 50 percent or more. Stator DesignThe design of the stator can help facilitate faster and easier replacement. Each stator inherently uses compressive forces in the design that compresses around the outside of the rotor; which in turn creates the sealing line of the pumping elements. These compressive forces are what make the pump work. However, they also make it harder and more time consuming to replace the stator with a new one. A new stator requires a great amount of force to install. Netzsch offers a time-saving stator replacement option. The iFD-Stator® design allows for the compressive forces to be released/removed during installation (and removal). Unbolting the compressive shell releases the axial and radial compression of the stator on the rotor. This allows for the new stator tube to slide on with relative ease and then be clamped down without the need for extra turning forces (see figure 2). Money-saving stator adjustments can also compensate for wear, using compression to re-establish the stator sealing line, increasing operational life and bringing the stator back to factory performance. The process can extend stator life of up to six times. This is a boon to operators, who would otherwise have to take the pump out of service, shut down the entire process, and lose all the revenue from that train. While standard stator replacement may take as much as six hours, with the Netzsch xLC® (stator adjustment device) attached to a pump, it takes less than two minutes (while pumping or not) the stator can be easily adjusted/tightened to renew the performance back to factory standards (see figures 3 and 4).A LOOK AHEADIn next month’s conclusion to this series, we’ll take a deep dive into the various materials of construction compatibility as well as concerns over solids handling and fluid media size. We’ll conclude with a detailed examination of serviceability option. JEFFREY BYE is municipal director for Netzsch Pumps USA.

40 | AUGUST 2024 WWW.MPTMAG.COMMPTSEALING SOLUTIONSSEALING SOLUTIONSConventional wisdom is to locate digester heating systems on or around the floor of the main digester. While this results in good initial heat transfer and creates thermal currents in the digestate to assist mixing, the accumulation of sediment quickly diminishes these properties and regular cleaning is necessary to maintain satisfactory performance with such systems. In some cases, heating units have actually been incorporated into the concrete walls or floor of digesters adding to the potential problems and expense should something go wrong.AN OUTSIDE VIEWThe solution is to locate the heating unit outside of the digester, an approach that is not new. One of the earliest uses of an external heater and heat exchanger for a digester dates back to 1946.Since then, external digester heating based on heat exchangers THE ADVANTAGES OF EXTERNAL DIGESTERHEATING Thinking outside the box (and the digester) toimprove performanceBY YENNI MAELIANAWATI, HRS HEAT EXCHANGERSExternal digester heating has a number of benefits over internal systems.

Over the years the design of heat exchangers has improved considerable and is epitomized by the HRS DTI Series of corrugated tube heat exchangers which are ideally suited for the external heating of digester fluids and sludge—and which have been successfully used in a number of such applications.EASY ACCESSThe biggest advantage of external heating is that it can be checked, cleaned, or serviced at any time without the need to empty (or enter) the digester, a process that is both costly and potentially dangerous. However, there are a number of other benefits, including the fact that external systems can be designed so that one heat exchanger array heats more than one digester.Also, the improved thermal performance reduces heating requirements and improves the overall energy efficiency of the AD plant. Where units are constructed of materials such as stainless steel, operating life is considerably improved compared to internal heating units, and routine maintenance is straightforward.STRENGTH IN NUMBERSThe HRS DTI Series is a true counter-current heat exchanger, meaning that the product flows through the inner tube and the service fluid flows through the surrounding shell. HRS’s corrugation technology increases both heat transfer and efficiency over standard smooth tube heat exchanger designs and minimizes fouling, and important consideration when dealing with materials such as digester sludge. Multiple units can be interconnected and have the options of frame mounting, insulated, and clad in stainless steel. HRS has installed several external digester heater systems at AD plants using its DTI Series of corrugated tube heat exchangers.Located in Georgia, HRS Heat Exchangers is part of the EIL Group (Exchanger Industries Limited) which operates at the forefront of thermal technology.
