Wastewater Treatment Case Studies and White Papers

  1. Concord, Massachusetts WWTP - A Low-Cost, 20-Year Solution To Ever-Tightening Phosphorus Limits

    Prior to 2007, Concord, Massachusetts wastewater treatment plant operated under a NPDES permit that allowed a seasonal phosphorus limit of 0.7 mg/L. But with the issuance of a new five-year permit with a phosphorus limit of 0.2 mg/L and the probability that future limits could reach as low as 0.05 mg/L, Concord needed a treatment solution that would be reliable and cost-effective today and over the long term.

  2. Ultrasonic Sludge Disintegration: A ‘Bubbly’ Solution For Anaerobic Digestion Or BNR

    ‘Sonicating’ sludge proves to be a sound method for handling biosolids. By Bryen Woo, aerobic digestion product manager and James Goldhardt, anaerobic digestion group manager, Ovivo

  3. Ultrapure Water In Semiconductor Plants

    In the semiconductor industry, ultrapure water usage can be in order of 2 to 4 million gallons a day. The entire ultrapure water treatment process is comprised of two segments: makeup water and a high-purity water loop.

  4. Smart Water: Remote Sensing

    Automated metering systems (AMSs) or “smart meters” can provide valuable data for electric and water utilities. Data analytics can be used to improve customer service, boost conservation, monitor the system, and even forecast demand. An ultimate goal might be to eventually monitor everything from streetlight intensity to fire hydrants.

  5. Verify Fluid Flow To Your Analyzer And Keep Your Plant Running

    No matter how sophisticated a fluid analyzer system may be, it will be ineffective if a sample flow fails to reach the analyzer sensor or if the sample is contaminated or stale. 

  6. Wastewater Treatment Plant Takes A Bite Out Of Tough Solids

    The City of Hammonton’s original steel bar screen rusted while continually allowing debris to pass through to the oxidation ditch and final clarifier. Floatables found their way through the plant to the UV trough, clogging the RAS and internal recycle pumps along the way. Managers of the Hammonton Wastewater Treatment Plant took on the challenge of finding a more efficient screening system. By JWC Environmental

  7. High Efficiency Media Filtration And Ultraviolet (UV) Disinfection Is Becoming A Crucial Component For Today's Cooling Tower Needs

    An increasing number of technology industries are turning to cooling towers to remove excess heat from buildings or processes. Server farms or server clusters are typically located between the system switches and routers, the removal of heat from these facilities is critical to their optimal performance.

  8. Case Study: Advanced Circulation Technology Combined With Solar Power Cuts Expensive Aerator Run-Time And Provides Efficient Mixing In Wastewater Treatment Ponds
    The energy and maintenance costs associated with mechanical aeration are compelling managers of municipal and industrial wastewater treatment plants (WWTP) to find alternate technologies. The goal is to provide more efficient wastewater aeration and mixing by reducing high operation and maintenance costs associated with mechanical aerators. By Joel Bleth, President, SolarBee Inc.
  9. High Recovery Reverse Osmosis Water Treatment For Industrial, Agricultural, And Municipal Applications

    Industry accounts for nearly 60 percent of fresh water withdrawals in the developed world and agriculture consumes 70 percent of fresh water supplies globally, according to UNESCO.

  10. White Paper: Passive Filter - Sustainable BMP For Permanent Stormwater Treatment Of Heavy Metals, Nutrients, Hydrocarbons And Sediment
    Passive filtration provides a sustainable alternative to classical drainage concepts for source control of hydrocarbons, heavy metals, and nutrients that endanger our water bodies. In urban areas with high building density, traditional drainage concepts like wetlands are not available and the concept of decentralized treatment facilities that can be housed in catch basin structures are a viable option for treatment of pollutants.
