WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Converters: The Real Heroes Of Flow Measurement

    Durable and reliable flow meters play a vital role in municipal water operations, but having the right converter to capture and transmit the resulting information is critical to maximize their value. Converters are expected to be robust and too often are taken for granted. Selecting the right converter to pair with your flow meters can make the difference in whether your data provides an average return on investment or the maximum benefit.

  • Best Strategies For Monitoring And Control Of Ozone And Biologically Active Filtration Systems

    There are many ways to monitor and control ozonation and biologically active filtration systems and operators need to know which one will work best for the intended application.

  • Easy To Digest: H2S Removal Rids City Of Lift Station Odors

    A constant problem in many wastewater collection systems is the formation of hydrogen sulfide (H2S) in the lift stations as well as from biofilms further downstream in the delivery piping to the wastewater treatment plant. DO2E representatives suggested that the City of Taylorville (IL) use their proprietary digesters equipped with an ozone (O3) capability to remove this problem from our system.

  • The Importance Of pH Levels In Water Treatment

    Recognizing pH's pervasive influence empowers operators to achieve consistent and reliable outcomes in every facet of water and wastewater treatment, underlining its indispensability for clean and safe water systems.

  • Advanced Ozone Disinfection – City Of Fayetteville, Arkansas

    Discover how Fayetteville upgraded wastewater disinfection with advanced ozone technology, improving contaminant removal, reducing energy use, and delivering reliable, sustainable treatment for future regulatory demands.

  • Dual Mixers Overcome Stratification And Prevent Ice Formation In Concrete Tank With Baffles

    The climate in Southgate, Ontario, is considered cold and temperate with significant rainfall throughout the year. Temperatures in winter average around -10°C and can drop as low as -30°C to -40°C for brief periods of time, which can wreak havoc on the local water storage tanks and distribution piping. Read more to learn how the installation of PAX Mixers has kept the tanks free from ice and has shown an improvement in disinfectant residual levels.

  • Accuracy And Reliability With A High Solid Content Slurry

    Burnett Lime Co. Inc., a leader in industrial and municipal water and wastewater treatment pH control, approached Pulsafeeder for a solution to a problem they were encountering in a key point of their process.

  • Sonoma County Improves Sludge Handling With Screw Press Pump Technology

    When California’s Sonoma County Water Agency (SCWA) wanted to improve its sludge solids dewatering as part of a major sludge handling upgrade, they were seeking an alternative to outdated sludge belt press/conveyor technology.

  • Featured Profiles In Brewery Wastewater Success

    Stories of real success with packaged pumping and wastewater treatment systems at breweries are explored, including for regulatory compliance and/or water reuse capabilities. Packaged pumping and treatment systems have helped hundreds of brewers meet their permits for local collection and/or direct surface discharge.

  • Oldest Town In West Virginia Adopts Modern Wastewater Treatment System

    As with many of today’s aging plants reaching 30+ years of service, the outdated technology and in-efficiencies had placed a burden on a West Virginia town and its officials. The system was no longer able to accommodate the community’s growth or meet the effluent requirements on nitrogen and phosphorus.

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

This application note will explore installations of AquaSBR Systems worldwide in a variety of municipal and industrial applications. 

To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past. 

A tube diffuser BIOFLEX® consists of a support tube with an inside thread and slotted sleeve membrane. Two hose clamps fasten the membrane onto the support tube and an O-seal is applied for sealing between the distribution pipe and the diffuser element. To avoid buoyancy the support tube is flooded. Tube diffusers are usually installed in pairs either by a pipe clamp fixed on a round tube serving as a distribution pipe or by a double nipple inserted into a rectangular tube. When air is supplied, it is directed through the head of the support tube under the membrane. Through the slots of the membrane the air is smoothly dispersed into the wastewater.

The Aztec 600 Ammonia Analyzer AW632 offers reliable and accurate on-line analysis of ammonia and ammonium ions up to 3 ppm NH3.

The AQUATek 100 is a purge and trap autosampler that automates the sample preparation steps for the analysis of liquid samples utilizing a fixed volume sample loop filled using a pressurization gas. Two independent volume programmable internal standards are then added to the sample and the entire aliquot is transferred to the Purge and Trap for compound concentration and subsequent separation and detection using a GC/GC-MS quantification system.

Base Mounted Pump Stations are pre-engineered units with an extensive selection of pumps, motors, controls, piping and accessories.

LATEST INSIGHTS ON WASTEWATER

  • Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
  • Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
  • Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.

  • Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
  • Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
  • Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.
