Wastewater Contaminant Removal White Papers & Case Studies

  1. Solving Foaming Problems At Your WWTP
    3/1/2015

    This project provides an unusual "before-and-after" comparison of how a high-solids loaded digester system with a Rotamix mixing system performed before and after the Foambuster was installed.

  2. Improving Influent Screen Washing For A Fraction Of The Estimated Cost
    3/1/2015

    The use of Vaughan's self-priming chopper pump and nozzles upstream of the influent screens is increasing the amount of fecal matter passing through the influent screens, which in turn improves plant efficiency and greatly increases the amount of cogenerated electricity from digester gas.

  3. Would You Like Some Free Green Energy With That?
    2/12/2015

    Some of the world’s most environmentally efficient and profitable green energy technologies are being specifically tailored to the needs of the beef, poultry, pork, rendering and stockfeed industries.

  4. Envirex® Energy Efficient Activated Sludge Process Meets Stringent Regulations While Minimizing Costs
    2/4/2015

    The Town of Elkton, Maryland, located in Cecil County near the head of the Chesapeake Bay, has a population of approximately 15,000 and an average elevation of 9.1 m (30 ft). Elkton is an economically strong, stable community that is very conscientious about environmental issues. In an effort to protect the Chesapeake Bay aquatic life, new stringent wastewater effluent regulations were implemented requiring very low nutrient levels in wastewater treatment plant discharge.

  5. Headworks Bio Commissions First IFAS System In Costa Rica
    1/2/2015

    In late 2013, Headworks Bio Inc. was awarded a contract with General Contractor Soluciones Tecnicas Ambientales, S.A. (SOLAMSA) to supply an IFAS system to upgrade the existing Ptar El Roble conventional activated sludge (CAS) treatment facility in Puntarenas, Costa Rica — the first IFAS installation in the country.

  6. Microbial Control In Cheese Making
    12/5/2014

    Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

  7. VLR® System For Biological Treatment Case Study
    10/8/2014

    Economic development has its price and sometimes calls for major upgrades to a community’s wastewater treatment facilities.

  8. Dairy Collective Reaps Green Energy And Environmental Benefits With Anaerobic Wastewater Technology
    9/16/2014

    One of the United States’ newest dairy processing plants features advanced wastewater treatment technology that not only radically improves biomass recovery and effluent quality, but also harnesses green energy from waste streams to drive production processes and reduce its carbon footprint.

  9. Two AquaDisk Cloth Media Filters Replace Six Granular Media Units, Boosting Capacity 540% And Cutting Backwash Volume By 97%
    8/14/2014

    The Portland, Indiana, Wastewater Treatment Plant (WWTP) had been using six granular-media filter units for tertiary treatment since the 1980s. The plant’s treatment protocol includes fine screens for grit removal, followed by primary clarifiers, trickling filters, aeration basins, secondary clarifiers, the tertiary treatment system, and then chlorine disinfection.

  10. Replacement Vacuum Feeders For Hypo Treatment End Heavy Feeder Maintenance Burden At WWTP
    4/30/2014

    The instrumentation supervisor for the City of Baltimore, MD’s 150-MGD Back River wastewater treatment plant (WWTP) reports that replacement of problematic vacuum feeders with more advanced vacuum feed units has ended heavy maintenance burdens associated with sodium hypochlorite (hypo) treatment of plant effluent.
