WASTEWATER CASE STUDIES AND WHITEPAPERS

  • The Principles Of Aeration And Mixing Utilizing Process Aerator Technology

    In the design of wastewater treatment plants, aeration typically involves supply of both oxygen and mixing. Aeration is a large consumer of both energy and operational costs. The Aire-O2 Triton aerator/mixer is a process aeration technology that addresses both of these aspects and is environmentally friendly, which is a winning formula to help achieve long term sustainability. By Cheri D. Cohen, Aeration Industries International, Inc.

  • HeadCell Eliminates Chandler, AZ's Punishing Grit Problem

    Rapid population growth created the need for a plant initially designed for 5 MGD to expand four times over two decades to treat 27 MGD today. With no grit removal the plant struggled with grit since start-up, spending hundreds of thousands of dollars on contractors to remove accumulated grit every 2-3 years. The plant wanted to eliminate their grit problems once and for all. Tired of wasting money, time, and effort on this futile but necessary task, the plant hired Wilson Engineers to evaluate various grit removal technologies to determine which type of system would be capable of eliminating their grit problem.

  • Turbo Blowers For Wastewater Treatment: Efficiency, Benefits, And Maintenance Considerations

    Turbo blowers improve wastewater aeration efficiency through high-speed impellers, lower energy use, and minimal maintenance, making them ideal for continuous, high-pressure applications when properly selected and maintained.

  • Vital Fire Suppression Line Remains Live While AVT EZ Valve Is Installed

    A major Texas-based refinery provides significant feedstock flexibility and product diversity to the area’s operations. The plant dates to the early 1900s and following upgrades now produces more than 125,000 barrels per day. A vital element of any refinery is its ability to be constantly ready to respond to a fire, so when the refinery found an inoperable valve on its 12” carbon steel fire suppression line and was in need of a way to add a valve to their system without shutting down the line, their maintenance and repairs contractor, ISS, suggested installing an AVT EZ Valve.

  • Case Study: Warm Springs Replaces RBC System With True Batch AquaSBR® Technology To Meet Effluent Requirements In Limited land Space

    Warm Springs Wastewater Treatment Plant (WWTP) was incorporated in 1950 and utilized a RBC system with secondary clarification and chlorine disinfection to meet BOD and TSS treatment objectives

  • MBRs As A Compliance Safety Net: Keeping BOD/TSS Below Detection Even Under Stress

    Maintain strict permit compliance even when hydraulic shocks or seasonal loads hit your system. Membrane filtration ensures dependable removal of solids and organic load, providing a critical process stability buffer against unexpected compliance risks.

  • An All-New Treatment Facility Is Designed To Meet The Clean Water Needs Of Future Generations

    About an hour south of Atlanta, the city of Barnesville, Georgia is a town of shady, tree-lined streets, a fondness for celebrating its history, and a sharp eye on the future.

  • Mass Flow Meter Best Practices For Water Treatment

    Air/gas mass flow meters find a variety of applications in many of today’s large urban water treatment plants, both clean water and wastewater. From measuring disinfection gases to controlling air or gas flow in digesters and aeration systems, the proper application, installation and operation of mass flow meters improves process efficiency as well as end product quality while at the same time reducing plant operating costs

  • Sturbridge POTW: Greater Capacity For High Flow Events, Enhanced Clarification For New Regulations

    Sturbridge, Massachusetts historically suffered from periodic blooms of filamentous bacteria that caused bulking in the secondary clarifiers of their three activated sludge package plants.

  • Green Stormwater Infrastructure Is Having Its Day

    Not long ago, systems engineered to manage and mitigate stormwater runoff were predominately of the “gray” variety. Today, however, more and more municipalities are embracing green stormwater infrastructure (GSI).  

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

Aquatech has been providing integrated water treatment solutions to the oil and gas industry for more than 30 years, ensuring our customers’ production and refining processes operate in an efficient and safe manner.

Raketec is a multiple-rake bar screen system with no moving parts under grade level. It is a two-chain, free sprocket mechanism guarantying reliability and ease of use. A combination of stainless steel rakes, and durable brushes thoroughly cleans debris from the screen.

Brentwood tube settlers consist of a series of sloped, tubular channels and structural wave sheets that reduce settling distance and combine to form an increased effective settling area. Constructed of robust, yet lightweight PVC, the modules can be supported with minimal structures while maintaining tensile, flexural, and impact strength. Heavy duty sheets are available for high-load applications.

Kruger’s ANITA™ Mox process combines nitritation and anammox reactions in an MBBR biofilm process using a single reactor. The reactions are maintained by control of DO in the reactor.

As the final step before treated wastewater leaves the plant, effective disinfection is extremely important to protect human health, and the maintenance of the environment. This process eliminates pathogenic organisms that cannot be removed by previous treatment steps and reduces the spread of pathogens in the natural ecosystem.

USP’s current offerings include our unrivaled in-house CFD modeling expertise that can be used to optimize the injection, mixing and feed rates of PAA to meet the disinfection requirements of a facility. Also, launching later this year, is our OaSys iCT™ is a novel control approach that optimizes disinfection performance by calculating the optimal chemical dosage that accounts for sources of treatment variability in real time. Available for use with PAA or chlorine.

Veolia’s STREAMLINER™ range of de-oiling hydrocyclones incorporates unique design features to improve reliability, performance and efficiency for produced water treatment processes.

LATEST INSIGHTS ON WASTEWATER

  • People around the globe are trying to figure out how to save, conserve, and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater. But for all the clean water they may produce, those processes leave behind a type of liquid called brine. I’m working on getting the water out of that potential source, too.
  • As water systems become more circular and complex, understanding and managing the subsurface — the hidden half of the water cycle — is becoming a critical enabler of resilience. This article explores the key trends shaping this new reality, from tackling “forever chemicals” to the water strategies redefining heavy industry.
  • The White House has finalized plans to roll back rules under the National Environmental Policy Act (NEPA), narrowing its focus and limiting what the current administration claims are needless delays for federal approval of water, energy, and other infrastructure plans. For water and wastewater utilities, the changes could speed up permitting for critical projects, although experts warn the tradeoffs could do more harm than good.
  • Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.
  • While many scientific and technical reports show that floods are becoming larger and more common, reports underestimate how their frequency is changing. Flood sizes get the spotlight, but governments and experts need to also consider their frequency to address implications overlooked by traditional management methods.
  • In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
