Session A: New Technology Moderator: Bernie Robertson Room: Ballroom A1 10:45 AM to 11:20 AM -- Cost-Effective MBR Treatment System to Meet ENR Limits Presenter(s): Chintan Parikh

There have been several projects throughout the country, where engineers after thorough evaluation including capital cost, operating cost and Net Present Worth over 20 yrs have selected MBR technology over conventional technologies for wastewater treatment. While this is observed for several Greenfield projects, it is almost a no-brainer when it comes down to retrofitting existing basins with a MBR. The biggest savings in retrofit applications comes from concrete costs; new concrete basins are not required, and the rated capacity of the wastewater treatment plant can be increased a minimum of three times the original capacity. No other technology besides MBR technology is capable of producing reuse quality water without the need for tertiary filtration. MBRs are also the preferred solution for meeting low nutrient limits; TN < 3 mg/l and TP < 0.1 mg/l. Besides lower capital cost, the MBR option also simplifies the number of unit operations and routine maintenance work for treatment plant operators. Over the years, the technology has developed and the operating expense of running an MBR system has reduced significantly with reduction in air scour energy demand and smart control systems. This presentation shows several case studies, with information on MBR retrofit projects as well as simplified operation and maintenance of an MBR system.


Session A: New Technology Moderator: Bernie Robertson Room: Ballroom A1 11:25 AM to 12:00 PM – Practical Applications for Cell Lysing Presenter(s): Dr. Klaus Nickel

Ultrasonic technology is one of several methods of cell lysing. In Europe this is common technology, with over 200 units installed and operating. There are many applications for ultrasonic cell lysing, for both anaerobic and aerobic applications. These include: pretreatment of aerobic WAS prior to anaerobic digestion; production of a carbon source for optimum BNR performance; partial breakdown of complex wastes to enhance aerobic or anaerobic treatment; control of nuisance bulking and filamentous bacteria; and ultrasonic treatment within agricultural waste treatment systems. The goal of ultrasonic cell lysing is typically the enhancement of treatment processes for a better and faster outcome, along with an improvement in treatment cost and residual management. This presentation will provide a short description of ultrasonic technology. Then, a number of case studies will be presented on various applications including treatment of TWAS prior to anaerobic digestion, control of filamentous bacteria, treatment of agricultural waste, and ultrasonic treatment of WAS as a carbon source. Each of these applications will be presented using sound scientific methods, such as side-by-side data of ultrasonically treated vs. untreated systems and corresponding results. Each of these applications has been previously presented at scientific conferences world-wide. Dr. Klaus Nickel has a Doctorate of Engineering from the University of Hamburg, has over 20 years of ultrasonic treatment experience with both a research and practical applications viewpoint, and is author or co-author of over 200 technical publications and presentations for ultrasonic technology. He is a frequent presenter at international and national conferences world-wide, and is fluent in both German and English languages.


Session B: POOP-ER-EE Moderator: Tom Fitzwilliams Room – Ballroom A2 10:45 AM to 11:20 AM – UV Basics, Adoption, and Advancements in UV Technology Presenter(s): Rob Jansen

The presentation will go through UV basics, theory and design considerations before discussing different types of UV and the latest advancements in the technology. It will finish with discussing some operational and maintenance information followed by a brief question period.


Session B: POOP-ER-EE Moderator: Tom Fitzwilliams Room – Ballroom A2 11:25 AM to 12:00 PM – Level Measurement in Water Collection Systems Presenter(s): Jim Burke

Water collection systems require measurement technologies to operate efficiently and safely while meeting regulations. There are a number of technologies available, and with the multitude of available options of bubblers, pressure sensors, ultrasonic devices, and radars, choosing the most reliable and effective instrument to meet your needs can be overwhelming.

This presentation will cover common, specific applications within the collection system, including lift stations, intake channels, and combined sewer overflows to name a few. Each of these applications comes with their own unique challenges for getting accurate measurements. These challenges can range from natural disturbances like excessive noise or hazardous weather to problems all too common in wastewater: fats, oils, grease, and excessive foam.

Every device handles wastewater challenges differently. The pros and cons of these measurement devices for these applications will be examined, ranging from their ease of use to their accuracy. This will help participants draw their own conclusions as to what technology will best meet their needs. Attendees will not only understand their options, but be able to confidently discuss those options and find the right instrumentation to meet their needs with their preferred vendor.


Session D: Biosolids Moderator: Jeremy Cramer Room – Ballroom A1 1:30-2:00 pm– R2E2 – It’s Alive! Presenter(s): Bruce Bartel, Jake Becken

Over the past three years, NEW Water (GBMSD) has implemented a project to replace all of the solids handling facilities. The name of the project is the R2E2 (Resource Recovery and Electrical Energy) Project. This is the largest capital project in the history of NEW Water.

The new solids handling facility consist of two new anaerobic digesters. The gas from the digesters is being recovered and used for energy recovery using two new internal combustion engines (generators). The digested sludge is dewatered using new centrifuges. The thickened sludge from the centrifuges is fed to a new scalping dryer that uses hot thermal oil. The dried sludge is then fed to a new fluid bed incinerator. The energy recovered from the new processes is expected to decrease NEW Water’s energy consumption from the grid by approximately 50%.

The R2E2 Project was divided into two phases. The first phase, which include a new primary substation, was completed in March 2015. The second and main phase of the project began in August 2015 and has been completed and is currently going through the start-up and commissioning phase.

This presentation will discuss the following:

The types and sizing of equipment installed.

The expected benefits from the project.

Recap of phase 1 construction.

Recap of phase 2 construction.

Start-up and commission experiences including the good, the bad, and the ugly.

Energy recovery data and results.

Development and implementation of a high strength waste receiving program.


Session D: Biosolids Moderator: Jeremy Cramer Room – Ballroom A1 2:05-2:40 pm – City of Baraboo Reduces WRRF Project Cost by Self-Performing Work Speaker: Kyra Peach

In 2018, the City of Baraboo upgraded the Biosolids process at their Water Resource Recovery Facility. The project included the replacement of the aging belt filter press equipment with a centrifuge, replacement of the alkaline stabilization process equipment, and a major building renovation. The City’s plant operators’ involvement in the equipment selection process, and the completion of some of the construction work during the project significantly reduced project costs. The City’s staff conducted several pilot studies prior to design, helping them to decide which equipment provided the best results. They also completed selective demolition and equipment removals. Most importantly, the operators developed a temporary Biosolids dewatering and stabilization system, which they operated while the building renovation took place. The presentation will provide a brief overview of the City’s new Biosolids process, explain the process the City used to select and purchase equipment, and detail the construction work performed by City’s staff. The presentation will focus on the areas of the project where the City was able to save their community a significant amount of money by self-performing work.


Session D: Biosolids Moderator: Jeremy Cramer Room – Ballroom A1 2:55 to 3:25 pm – Biosolids/Compost Pilot Project Presenter(s): Jeremy Cramer

This presentation will cover a biosolids compost pilot project that was completed at the Fort Atkinson WWTP in 2018. An aerated static pile compost pilot was used to demonstrate if aerobically digested biosolids produced at the WWTP could be successfully composted with City of Fort Atkinson yard waste (woodchips, leaves, and yard debris) to produce a Class A biosolid. The purpose of the pilot was to determine the volume of biosolids that could be composted in a year, space requirements, bulking agent (Carbon) requirements, equipment requirements, air requirements, and staffing hour requirements. The Fort Atkinson operations staff was very involved in the compost pilot project from the inception of the project to the completion of the project. There was also a compost survey sent out to surrounding landscapers, excavators, landfills, highway departments, sod farmers, and nurseries to identify potential interest in a City Yard Waste derived compost.


Session D: Biosolids Moderator: Jeremy Cramer Room – Ballroom A1 3:30 to 4:00 pm – Unique Thickening and Dewatering Operations Related to Nutrient Removal Operations Presenter(s): Allen T. Williams, P.E.

The presentation will cover the unique thickening and dewatering operations related to the Lystek and Ostara processes at the St. Cloud Nutrient, Energy & Water Recovery Facility. The thickening operations involve two GBT’s, with one GBT used for producing a 2% WAS product to be sent to a WAS P release tank (WASSTRIP process) and the other GBT used for co-thickening WAS P release sludge and Primary sludge to 9%. The co-thickened 9% sludge is anaerobically digested with HSW substrates. The filtrate from the co-thickening GBT is further processed in the Ostara nutrient removal process. There is also a centrifuge that is used to dewater the anaerobically digested biosolids to a 14% cake product that is fed into the Lystek process. The Lystek process produces a Class A liquid 10% biosolids product that is land applied. The centrate from the centrifuge producing 14% cake is sent to the Ostara process for nutrient removal. The facility runs the GBT’s on a continuous basis 24 hours per day 365 days per year and runs the centrifuge process 48 to 72 hours continuous per week. The operations staff at the facility has been operating the two processes for approximately one year and there have been many interesting challenges related to the processes. This presentation will discuss the processes, the challenges encountered, and how the two processes have operated for the past year.


Session E: Primary / Grit Removal / Headworks Moderator: Kelly Zimmer Room – Ballroom A2 1:30 PM to 2:00 PM – Grit – It’s Not Just Breakfast Anymore Presenter(s): Rusty Schroedel

The presentation will first provide a detailed description of what grit is, noting it is not just sand or sand like solids but several particles that are heavier and more settleable thant other solids in the wastewater. These “grit” particles can be coated with substances like grease which can impact their ability to be removed with typical grit removal equipment. Reasons why operators and design engineers should care about the efficiency of their grit removal systems are reviewed. The characteristics of several different types of grit removal equipment will be described. Some project case histories will be presented. Lastly, other considerations will be offered, as well as conclusions, and recommendations for understanding grit removal, identifying potential improvements to existing systems, and potential approaches for installing new grit removal systems.


Session E: Primary / Grit Removal / Headworks Moderator: Kelly Zimmer Room – Ballroom A2 2:05 pm – 2:40 pm – Primary Sludge Grit Removal Presenter(s): Tom Foley

Clark Dietz, Inc. was chosen by the Evansville Water and Sewer Utility (EWSU) to serve as the lead engineering consultant and overall project manager for the design of a facility expansion for the East WWTP in Evansville, Indiana. The EWSU has experienced difficult pumping conditions for the grit pumps due to the depth of the grit basins. As a result, large amounts of grit bypass removal and settle in the primary clarifiers. The issue was first identified during digester cleaning when large deposits of grit were discovered. Further sampling confirmed excessive concentrations of grit in the primary sludge stream. Separating grit from primary sludge is difficult due to the viscosity of the sludge. Therefore, EWSU will increase the primary sludge pumping rate to thin the sludge to <1% in order to remove grit using a vortex flow grit removal unit. Following grit removal, the primary sludge will be thickened prior to digestion. This new system is expected to improve the primary clarification process, remove grit from the primary sludge stream, and provide a more continuous, thicker primary sludge stream to the digesters.


Session E: Primary / Grit Removal / Headworks Moderator: Kelly Zimmer Room – Ballroom A2 2:55 – 3:25 PM – Headworks facilities Evaluation-operator Driven Decision Making Presenter(s): Greg Gunderson, P.E.

In headworks facilities, there is a dizzying amount of equipment to consider, which can make it difficult for a community to select the right equipment for them. The Village of Grafton was in need of new headworks facilities. This presentation will cover the process utilized to select the equipment that allowed for a true operator-driven solution. The presentation will cover the evaluation of screening, grit, and influent pumping equipment.


Session E: Primary / Grit Removal / Headworks Moderator: Kelly Zimmer Room – Ballroom A2 3:30 – 4:00 PM – Round Peg in a Square Hole: Manitowoc’s Novel Clarifier Replacement Project Adds System Flexibility Presenter(s): Troy Larson, Phil Severson, Mike Jaeger. Brian Helminger

Manitowoc’s WWTF Improvements Project, completed in 2018, prioritized replacement of aging equipment throughout the facility and provided new flexibility. During planning, the plant superintendent suggested a creative solution to an ongoing seasonal issue: replace the existing rectangular clarifiers with one that capable of operating as a primary clarifier or as an intermediate clarifier. The Engineer and City collaborated to implement this idea.

This presentation will highlight the process improvements included with the primary clarifier replacement as well as other aspects of the project. The presentation will include the following:

Facility background

New primary clarifier performs two functions and adds value

o Review the need for replacement and operational issues

o Review the new clarifier and two modes of operation

o Discuss design and construction of the new clarifier

o Review operator strategies for when and why operate in one mode versus the other

o Discuss the operation of the new clarifier, lessons learned, and performance

improvements

Sludge heat exchanger control improvements and boiler addition saves on natural gas

New workhorse final effluent pump saves electricity


Session F: Phosphorus Moderator: Jeff Smudde Room – Ballroom A3 1:30 PM to 2:00 PM – The Route to Developing a Phosphorus Compliance Plan Presenter(s): Jonathon Butt, Tim Nenning

It has been a long road. Addressing new phosphorus effluent limits required by WPDES permits takes know-how, research, and collaboration. After 4 years, the Village of Grafton has selected a final compliance plan for phosphorus that satisfies the new permit and reflects Grafton’s environmental stewardship. The planning activities taken by Grafton are a model example of one course to address new phosphorus effluent limits, which for Grafton were first identified in the July 1, 2015 WPDES permit later modified by the approved Milwaukee River Total Maximum Daily Load (TMDL) allocations.

This presentation will focus on the four main alternatives that were evaluated in both the preliminary and later in the final Phosphorous Compliance Plan. Those alternatives included:

Improvements at the wastewater treatment plant involving chemical addition and effluent filtration. Three different effluent filtration technologies were evaluated along with inclusion of algae treatment.

Nutrient trading involving an evaluation of the challenges of nutrient trading in the region combined with a summary of practices currently being used that would not qualify for producing credits.

Adaptive management involving an evaluation of the reductions needed along with potential projects that may support in-stream reductions.

Multi-discharger variance (MDV) involving an investigation on whether Grafton would qualify.

This presentation will conclude with a summary of the final plan, why this plan was selected, and how this how this plan works for the Village. It is hoped that other municipalities that are similar in size can learn from the Village’s approach and on the implementation steps for the final plan.


Session F: Phosphorus Moderator: Jeff Smudde Room – Ballroom A3 2:05 PM to 2:40 PM – Phosphorus Compliance Alternatives in Wisconsin Presenter(s): Leo Kucek

Wisconsin adopted new phosphorus standards for wastewater treatment effluent in 2010. Meeting these lower phosphorus discharge standards (<0.075 mg/L) presents major challenges for wastewater treatment facilities throughout Wisconsin. Compliance can be achieved through the use of several methods, including built alternatives, chemical phosphorus removal (CPR), the multi-discharger variance (MDV), and water quality trading (WQT). This presentation will compare the compliance alternatives using case studies for several wastewater treatment plants in southeastern Wisconsin. Our experience has shown that the lowest cost feasible alternative was a combination of CPR (via polyaluminum chloride addition) and a non-point source compliance alternative, such as the MDV or WQT. The MDV was determined to be especially favorable for eligible facilities, and conditional approval for the MDV was secured in several cases. Ultimately, with so many options available, a clear and comprehensive evaluation empowers communities to select the most cost-effective compliance alternative(s).


Session F: Phosphorus Moderator: Jeff Smudde Room – Ballroom A3 2:55 PM to 3:25 PM – Biological Phosphorus Removal: Energy-Saving Aeration and Mixing-Upgrade Pays Quick Dividends Presenter(s): Mark Stephanie, Dean LaFleur, Dylan Friss, Jim Fischer

INTRODUCTION The Village of Valders, WI, carried out energy-saving, process-enhancing upgrades at its wastewater treatment plant by converting from the conventional activated sludge process to the simultaneous nitrification-denitrification (SNDN) process. The goals of the upgrades, carried out in 2018, were to achieve the following 4 benefits:

1. To begin removing both phosphorus and nitrogen biologically. 2. To avoid or minimize the need for chemicals for phosphorus removal. 3. To pay for the upgrades via reduced energy consumption by mixing with low-energy

submersible propeller mixers instead of higher-energy conventional mechanical aeration. 4. To reduce maintenance by mixing with lower-energy submersible propeller mixers instead of

using higher-energy air and blower-power for mixing.

METHODOLOGY The existing conventional 2-zone aeration basin was sub-divided and re-purposed into 3 zones – 1) Anaerobic, 2) Aerated-Anoxic and 3) Oxic/Aerated zones. This arrangement, also known as A3O or SNDN, creates conditions for both phosphorus-removal and nitrogen-removal. A baffle-wall was added to subdivide one zone into two, for a total of three biological treatment zones. The first zone, Anaerobic, we equipped with a high-efficiency submersible horizontal low-speed adjustable-thrust propeller mixer. This enables good mixing without aeration, yielding anaerobic conditions favorable for phosphorus release and later phosphorus uptake. The second zone, Aerated-Anoxic, has the flexibility of aerating when needed to balance air with anoxic conditions. This balance is needed to enable favorable conditions for simultaneous nitrification-denitrification. The third zone, Oxic-Aerated, is fully aerated, enabling phosphorus uptake and ammonia removal. Existing fine bubble aeration system was replaced after determining it was beyond its useful life. Aeration is turned down and cycled on and off manually to create and balance anaerobic, anoxic and aerated conditions.


RESULTS

1. Treatment results: Total Phosphorus was reduced from about 2.3 ppm to below 1.0 ppm. 2. Energy savings: $3,000 annually due to high-efficiency submersible horizontal low-speed

adjustable-thrust propeller mixer using less electrical power than previously used by the fine bubble aeration system. With an estimated $3,000 future annual savings, the investment is estimated to pay for itself in 4 years.

3. Maintenance cost reduction: One 2.5 horsepower mixer with adjustable speed is expected to be less costly to service and maintain vs approximately 10 times the blower power needed for mixing before.

DISCUSSION The results are impressive considering the simplicity of the changes made. The village expected the upgrades to work, but were pleasantly surprised that the phosphorus removal and energy savings were as great as they are. Now they plan to expand the upgrade to the other half of the plant. In addition, these good results pave the way to add controls and automation to optimize for even better phosphorous removal and more energy savings. Further low-cost upgrades like adding air valves and blower controls could generate additional improvements. CONCLUSIONS Biological phosphorus removal is easier than the village thought. Getting phosphorus down from 2.3 ppm to less than 1 ppm by simply adding only a mixer, a baffle-wall, new air diffusers and manual air-control is a surprisingly good result for relatively simple measures. Moreover, paying for the changes with the energy saved in only 4 years makes a strong case to share this practice with others.


Session Session F: Phosphorus Moderator: Jeff Smudde Room – Ballroom A3 3:30 PM to 4:00 PM – Evaluation of High Precision In-Situ Analysis aAgainst Benchtop Lab Analyzers for Process Insight Presenter(s): Dave Rutowski

With phosphorus discharge regulations tightening in many watersheds plants are often looking at alternative treatment schemes to reduce phosphorus discharge. Biological Phosphorus removal is effective under proper conditions but without a complete understanding and insight into the process, changes may lead to reduction in BPR effectiveness. The intended benefits of a high precision automated analysis system include visibility to process changes, understanding influent influence, and ability to adjust the effluent phosphorus limit to remain in compliance. As part of global beta testing (US and US markets) the low range Phosphorus Analyzer (Phosphax sc LR) was evaluated at the wastewater plant in Janesville, Wisconsin. The plant operates as an extended aeration activated sludge plant that using Bio-P removal plus ferric chloride backup to precipitate phosphate to meet their current 1.0 mg/L monthly average total phosphorus limit and eventual TMDL permit limits averaging 0.075 mg/l. The phosphorus analysis system at Janesville, Wisconsin has proven that it will perform as expected and yield greater understanding of influent load and its influence on Biological Phosphorus removal. This data can then be used to adjust plant anaerobic, anoxic, and aerobic zones through modulating air flow control valves and mixers to optimize detention volume and treatment times. Additionally, the data can be used to dose ferric chloride in real time to meet an effluent setpoint.

Session Q: Energy Moderator: Ryan Hennessy Room: Ballroom A4 1:30 PM to 2:00 PM –Alternative Energy – Biogas Recovery Presenter(s): Jeff VanVoorhis

With renewable energy and sustainable initiatives at the forefront of modern development planning, it’s no wonder municipalities are looking in unusual places for solutions. Whether it’s the lure of financial incentives like RINS and LCFS or the desire to utilize assets more effectively, municipalities are in a position to generate substantial revenue from an unsuspecting source – their wastewater.

At the forefront of innovation, Symbiont has designed and/or built over 40 anaerobic digestion (AD) facilities that transform the raw biogas produced by their municipal wastewater treatment processes into pipeline quality RNG. These systems are not just for food and beverage production facilities. The two municipalities we will cover in this session are now creating over 1,000 gallons of gas equivalents (GGE) per day. Re-envisioning their wastewater treatment systems enables these communities to take advantage of RINS and LCFS incentives, fuel municipal fleets, save money, and sell RNG to others to support nation-wide alternative energy initiatives.


Session Q: Energy Moderator: Ryan Hennessy Room: Ballroom A4 2:05 PM to 2:40 PM – Biogas Upgrading for Vehicle Fuel and Pipeline Injection Presenter(s): Kim Murdock-Timmerman

As WWTP’s become more efficient, the RIN market increasing and paybacks for CHP projects are becoming extended, the biogas industry has seen an increased interest in Biogas to Vehicle Fuel and Biogas to Pipeline Injection projects. There are many options that take advantage of this potential revenue stream and how plants determine the best solution for the specific site has become an important topic.

Overview Biogas from Anaerobic Digestion has been used commonly for combined heat and power for almost 5 decades, since the sharp rise in fossil fuel prices of the 1970’s. As engines have become more efficient, and waste streams more contaminated, biogas conditioning systems have had to keep pace with developing technologies to provide cost effective solutions.

Biogas is no longer consider waste, but a powerful tool in our nations drive to become more sustainable and shift away from higher energy prices we have seen in the past. Our plants are now considered “resource recovery plants” rather than pollution control plants. To make economics better, old technologies are being improved and providing more cost effective solutions.

As WWTP’s become more efficient, the RIN market increasing and paybacks for CHP projects are becoming extended, the biogas industry has seen an increased interest in Biogas to Vehicle Fuel and Biogas to Pipeline Injection projects. Several new technologies are available for small scale and large scale pipeline projects. While the basic removal of hydrogen sulfid, moisture, particulates and siloxanes is fairly standard, the removal of carbon dioxide adds complexity to a system. Individual pipeline specifications also drive some of the fuel quality requirements. Small scale systems, up to 400 scfm have found membranes to be a cost effective solution for removal of carbon dioxide. New to the US market for larger flow systems is a chemical adsorption biogas upgrading process, captures over 99.9% of the available biomethane in raw biogas, maximizing renewable gas yields and revenues with a very low operational cost. The pipeline quality renewable natural gas can be compressed for vehicle fuel, grid injection, or liquefied for renewable LNG.

Case studies for both vehicle fuel and pipeline projects will be discussed along with the options available to optimize a system.

Session Q: Energy Moderator: Ryan Hennessy Room: Ballroom A4 2:55 PM to 3:25 PM – Got a Minute? I Have Another Quick Generator Question Presenter(s): Steven Muther, P.E.

Given the wide range of considerations in designing a standby generator system, there is seldom such a thing as a “quick generator question.” And as this title suggests, one question often leads to another. This presentation describes the many factors to consider when specifying or selecting a standby generator system. Those factors include evaluation of space and site constraints, the nature of the loads, as well as the need to comply with the various current electrical, building, environmental, and water/wastewater codes Tightened emissions standards adopted a few years ago are just now impacting the market, affecting cost and product availability. The intent of this presentation is to help municipal personnel be more knowledgeable on the subject when faced with a generator upgrade or new installation.


Session Q: Energy Moderator: Ryan Hennessy Room: Ballroom A4 3:30 PM to 4:00 PM – Energy Efficiency Starts With You Presenter(s): Joe Cantwell, Donald Hefty

Burlington Wastewater Treatment Facility has worked with Focus on Energy since 2002, to assess their treatment processes and operations to identify energy efficiency opportunities. They have been pro-active implementing modifications that are both energy efficient and provide operational flexibility. They have also developed an energy efficient culture, allowing Burlington to realize a continuous reduction in energy use and costs. Initial modifications targeted their major energy using process; blowers, diffusers and controls. However, having realized the savings from those modifications they continued to assess what other modifications they could do to continue an energy reducing trend. They succeeded in that effort because from 2012-2018 it has further reduced energy costs by $8,000 per month. The presentation will discuss the additional cost-saving measures they implemented to reduce energy use and monthly costs. These additional measures may be implemented at other facilities. Also shared will be how to develop an energy efficient culture within a facility.

Session I: Phosphorus Treatment Moderator: Jeff Mayou Room – Ballroom A3 8:00 AM to 8:45 AM – Newly Developed Cloth Media and Innovative Pilot Testing to Replace Your Tertiary Sand Filter Presenter(s): Matt Castillo, P.E.

Cloth media filtration has been studied and tested throughout the United States. This presentation will provide a performance evaluation of a new cloth media, originally designed for the pretreatment of drinking water. Full-scale testing was conducted at the City of Platteville WRRF. Testing included variable hydraulic and solids loading rates, an attempt to use solids to improve effluent quality, and the monitoring of phosphorus (speciation), TSS, turbidity, and particle size distributions. Bench-scale testing was conducted prior to full-scale testing. This presentation will discuss the new media, testing results, and the importance of a structured protocol.


Session I: Phosphorus Treatment Moderator: Jeff Mayou Room – Ballroom A3 8:50 AM to 9:35 AM –Sand Filter Conversion to Disc Filters for 0.075 mg/L TP Presenter(s): Ben Brooks, Eric Lynne

Medford, Wisconsin selected disc filtration to comply with low level effluent phosphorus limits of 0.075 mg/L. Of the many technologies, the City selected disc filtration, despite limited installs in the Central States region. The system includes coagulant addition in a rapid mix and coagulation zone, followed by polymer addition for flocculation of larger particles prior to filtration. The system was purchased with a performance guarantee, which was substantiated with numerous analyses and split samples providing unbiased verification of results in mid 2019. The results of the guarantee period are to be presented in the paper. Key features include validation of filtered effluent phosphorus levels with speciation for soluble nonreactive phosphorus and chemical doses with respect to other technologies.

Session J: Interceptor Cleaning/Maintenance Moderator: Nate Tillis Room – Ballroom A1 10:55 AM – 11:45 AM – Methods and Techniques for Cleaning and Maintaining Off-Road Sewers Using In-House Crews Presenter(s): Mark Grabowski, Bruce Ward

Every collection system has them - difficult-to-access off-road sewers. And they are usually the bane of the department’s existence. Between access issues and equipment deficiencies, they usually fall to the bottom of the priority list for maintenance. “Out of sight, out of mind” is all too often the approach. However, “deferred maintenance” will eventually catch up, and when it does, it can be expensive and catastrophic. This presentation will discuss some of the more common means and methods which these pipes can be shown maintained, or at the minimum, properly inspected and prioritized. The presentation will explain maintenance and inspection equipment & techniques that may help agencies – including smaller ones – tackle the job using in-house resources, without the major expense.


Session K: Variance/Rates Moderator: Lyle Lutz Room – Ballroom A2 10:00 AM to 10:50 AM – Regulations – Pollutant Variances Presenter(s): Laura Dietrich, Matthew Claucherty

Over 150 facilities throughout the State of Wisconsin have an individual variance for pollutants such as Chloride, Mercury, and Phosphorus. WDNR works closely with EPA and facilities during the permit reissuance process to produce an approvable final variance package. Changes to the Federal Codes that occurred in August 2015 have made requirements and expectations for applications and annual reports seem more difficult and the process lengthier. This presentation will focus on PMP/SRM development, variance justification, and annual reports to help make the process smoother for facilities.


Session K: Variance/Rates Moderator: Lyle Lutz Room – Ballroom A2 10:55 AM to 11:45 AM – The Cost of Clean: 23 Years of Sewer User Charge Trends in Wisconsin Presenter(s): Tom Fitzwilliams

What’s the true cost of safe and reliable wastewater treatment? This presentation will answer that question by providing a historical review of sewer user charges in Wisconsin over the past 23 years. The presentation will reveal results of the ninth survey report, with sewer service data gathered in January 2019. This year’s report will document the cost of sanitary sewer service in Wisconsin and provide communities with the ability to compare their current and proposed sewer rates with the rates of similarly-sized communities. With access to this information, communities are empowered to make the best decisions for a healthy and sustainable future. The new data will be compared to data collected since 1996. The data is used to illustrate the major factors impacting sewer rates, and will help the public understand why sewer rates can be vastly different in two neighboring communities. The research over the past two decades illustrates and provides reasons for the disparity in rates between residents of small communities versus those of large communities.


Session L: Troubleshooting Moderator: Sharon Thieszen Room – Ballroom A3 10:00 AM to 10:50 AM – Inhibition vs. toxicity in Wastewater Presenter(s): Ryan Hennessy

The presentation focuses on wastewater bacteria, known substances that interfere with treatment, inhibition, toxicity, and potential methods to help plants recover from a stressful event.


Session L: Troubleshooting Moderator: Sharon Thieszen Room – Ballroom A3 10:55 AM to 11:45 AM – Tricks of the Trade Presenter(s): Troy Larson, Sharon Thieszen, Tom Steinbach, Randy Oliphant

This will be the fourth submittal of this format for the Tricks of the Trade. This presentation will highlight innovations by many wastewater treatment professionals who have tinkered, invented and improved their workplace through their efforts. Images of their improvements will be displayed, and brief discussions will occur. The topics vary from sampling, maintenance, safety, public relations etc. Discussion from the floor is welcome.


Session M: CollectionSystems Moderator: Randy Langer Room – Ballroom A1 1:30 PM to 2:15 PM – Sewer Lateral Rehab Solves CSO Problems. A Lesson in Public relations and Community Buy-In Presenter(s): Thomas Nagle, P.E.

The Village of Olympia Fields continued to experience sanitary sewer overflows and basement backups despite extensive improvements to publicly owned infrastructure. Sewer system I/I investigations concluded that the remaining high wet weather flows were primarily caused by leaking sewer laterals. The Village elected to improve the laterals by installing CIP liner. Project success hinged on obtaining consent from a vast majority of the 141 residences to have their sewer laterals repaired. The Village was initially met with a strong opposition from many of the homeowners. A comprehensive public information and participation program, creative financing, and a positive team effort from the community, regulatory agencies, state legislators, the contractor and consulting engineers resulted in a 95% participation rate from residents and a true spirit of cooperation during project construction. The success of the project is demonstrated by dramatic reductions in wet weather flows and the elimination of SSO and basement backups.


Session M: Collection Systems Moderator: Randy Langer Room – Ballroom A1 2:20 PM – 3:05 PM – Stop Age Discrimination in Pipe Replacement Strategies Presenter(s): Steve Bruskiewicz

Steven Bruskiewicz serves as a Business Development Manager for Xylem/Pure Technologies US in the Upper Midwest.

Session N: Lagoons Moderator: Jeff Simpson Room: Ballroom A2 1:30 PM to 2:15 PM – Evaluating Lagoon Upgrades for Increasingly Stringent Effluent Limits Presenter(s): Travis Anderson

As municipalities and industries face increasingly stringent discharge permit effluent limits, lagoon facilities that have been used for decades are often no longer able to achieve compliance. In the face of new effluent limits, a decision to either construct a new mechanical wastewater treatment facility, upgrade existing lagoon facilities, or convey wastewater to another treatment facility must be made. Two case studies will be presented that highlight the technologies and alternatives considered for lagoon upgrades with varied project drivers. The first case study includes the design for improvements to a three-cell lagoon system treating effluent from a major dairy industry. The existing lagoons were constructed in the 1970s and include two 7.0 million-gallon aerated cells and one 0.6 million-gallon settling cell. Concerns with meeting effluent limits prompted the need for evaluating a variety of treatment alternatives. This evaluation included alternatives with and without reuse of the existing lagoon system. The alternative with the lowest opinion of total present worth includes a new lagoon aeration system and the construction of an attached growth nitrifying reactor. The second case study consists of a small sewerage district in Iowa whose newly reissued NPDES permit.


Session N: Lagoons Moderator: Jeff Simpson Room: Ballroom A2 2:20 PM to 3:05 PM – Optimizing Lagoon Based Treatment Systems to Meet More Stringent BOD, TSS, and Ammonia Limits Presenter(s): James Martin

“Modeling for Success – Taking Lagoon Process Design to the Next Level” Wastewater treatment process design modeling software, which models biological, chemical, and physical treatment processes, can be used to optimize the design, performance and reliability of lagoon based treatment systems. Lemna Environmental Technologies (LET) employs a dynamic wastewater treatment process simulation model, to analyze performance of existing facilities and the expected performance of proposed facilities. The modelling software is widely used in the wastewater community to investigate the impact of various changes in loadings and temperatures and allows LET to thoroughly verify process design and performance especially with regards to BOD, TSS and ammonia removal. Using historical DMR data from an installation base of over 200 facilities, LET created a unique software model of its LemTec Biological Treatment Process, which utilizes a combination of aerated and settling lagoon cells for biochemical oxygen demand (BOD) and total suspended solids (TSS) removal, and the Lemna Polishing Reactor (LPR) for nitrification. By calibrating the model through the analysis of historical operating data, the model can be used as an accurate predictor of process performance. The model may be manipulated to reflect the size, configuration, loading, aeration and effluent requirements for current or future facilities and is especially useful in predicting and troubleshooting nutrient removal. The model enables LET to consider the effects of non-steady state factors such as peak flows, constituent loading, and ambient air and water temperatures on treatment performance, improving upon traditional steady state wastewater treatment process design methodology. The discussion will provide data and specific case studies demonstrating the predicted performance vs. actual data, using the calibrated model.


Session N: Lagoons Moderator: Jeff Simpson Room: Ballroom A2 3:15 PM to 4:00 PM – Upgrading for Cold-Climate Nutrient Removal Presenter(s): Nick Janous

Lagoons are effective at removing BOD and Total Suspended Solids (TSS), but historically struggle to remove ammonia and nutrients, including nitrogen and phosphorus. As regulators seek to protect wildlife in receiving waterways, lowered nutrient limits are becoming common in lagoon-based wastewater treatment facilities. Using the WWTP upgrade in Sundridge, Ontario, this presentation will discuss the various options available for meeting phosphorus limits. We will then focus on the Sundridge solution, as well as its results - the system routinely reduces peak influent phosphorus as high as 8.3 mg/L down to non-detect levels well below the system’s 0.27 mg/L limit, as well as consistently removing 99% of TSS, 96% of cBOD, and 95% of TAN, all in water that cools to <1°C. We will also discuss Sundridge’s innovative recycle system originally intended to retain alkalinity for nitrification, which helped Sundridge address and solve the issue of decreased pH levels in their system, while also doing impressive work in removing nitrates.


Session O: Technology Moderator: Ryan Hennessy Room: Ballroom A3 1:30 PM to 2:15 PM – SCADA Networks – Mysteries Revealed! Presenter(s): Steven Muther, P.E.

Supervisory Control And Data Acquisition (SCADA) networks seem to have gotten more and more complicated in recent years, and to some degree, more mysterious. That’s mostly because, well, they have. The purpose of this presentation is to provide an overview of the parts and pieces of today’s SCADA networks, make the complex more understandable, thereby revealing the “mysteries.” Emphasis is placed on providing clear understandable descriptions of the various components in a SCADA network. A handout will be made available which can be used as a reference for the terms discussed.


Session O: Technology Moderator: Ryan Hennessy Room: Ballroom A3 2:20 PM to 3:05 PM – Creating Efficiencies Using Mobile GIS and Operational Dashboards for Wastewater Systems Presenter(s): Kyle Engelking

The margin for efficient and precise record keeping is razor thin today, as we can create and obtain data at the tip of our fingers 24/7. This has driven many utility operators to turn to an organizational Geographical Information System (GIS) to help maintain and improve their asset management systems and record keeping. This presentation will focus on how several small to mid-sized wastewater utilities have transformed their GIS into a mobile, real-time data source, to maintain their wastewater infrastructure assets and aid in various reporting activities. The presentation will focus on two different applications of GIS, namely collecting data in the field and viewing data quickly and easily in the GIS. The audience will take away an understanding of how these two GIS applications for wastewater utilities allow for more data driven answers facilitating fast and accurate data collection and decision making. Operators and other community decision makers will be able to incorporate a more diverse and robust data set for their statistics collection, asset maintenance, and reporting workflows.


Session O: Technology Moderator: Ryan Hennessy Room: Ballroom A3 3:15 PM to 4:00 PM – Augmented Reality GIS Systems Applications Presenter(s): Alex Sukupcak

The visualization of features in a spatial context is one of the greatest benefits driving organizations to implement geographic information systems (GIS). The ability to see how features are physically connected and how they interact is essential. Utilizing augmented reality, organizations can greatly enhance a user’s visualization of data. Augmented reality is an enhanced version of reality that superimposes computer-generated images over a user’s view of the real-world. By implementing vGIS, a mobile application that presents an organizations data in augmented reality, Symbiont has given field workers and managers the tools for visualizing their current water and wastewater utility GIS data in the field in 3-D. Utilizing augmented reality, an organization can gain further insight and clarity into tough decisions and be assured that they are making the correct decisions.


Session T: Septage Compliance & Master Operator Training Moderator: Steve Geis Room: Ballroom A4 12:30 PM to 4:30 PM – Septage Compliance & Master Operator Training Presenter: Fred Hegeman
