Wastewater Disinfection WHITE PAPERS

  1. AnoxKaldnes MBBR Proves Effective At Asphalt Refinery

    A refinery needed to upgrade the wastewater treatment system to prepare for expected changes brought about by the use of a new crude feedstock with elevated concentrations of TDS and conductivity. Veolia Water Technologies supplied an AnoxKaldnes Moving Bed Biofilm Reactor (MBBR) treatment system to reduce the BOD and ammonia in the effluent.

  2. Reducing Odor & Corrosion

    Veolia faced the daunting challenge of managing two large WWTP’s as well as finding a better and more cost effective solution for odor and corrosion control.

  3. SCU™ Trace Metals Removal Media Removes Heavy Metals For Battery Manufacturer Discharge Compliance

    In June 2011, Evoqua was contacted by a manufacturer of battery equipment for electric lift trucks. The systems are routinely used at many large food processing facilities in Texas.

  4. IFAS System Doubles Ammonia Removal Capacity

    In August of 2007, the Michigan Department of Environmental Quality issued seasonal ammonia discharge limits for the Coldwater Wastewater Treatment Plant (WWTP), which included a daily maximum ammonia concentration of 2.0 mg/L between the months of May and November.

  5. Installing Hydro-Guard® Automatic Flushing Saves Rural Texas Town $8,000 A Year

    Managed by the private, non-profit South Jasper Water Supply, Buna, Texas’ water system contains 91 miles of un-looped distribution pipe with historical water losses of up to 30%. A small operations team is responsible for monitoring two water plants, reading 700 meters, repairing leaks, and flushing water to control the water quality. In an effort to spend less time manually flushing hydrants and focus more time on repairing leaks to reduce non-revenue water loss, South Jasper Water Supply purchased and installed two (2) Hydro-Guard® HG-1 Basic/S Flushing Systems.

  6. Replacement Vacuum Feeders For Hypo And Bisulfite Boost Disinfection Reliability For WWTP

    The replacement feeders also cut bisulfite consumption by 30 percent and ended the troublesome maintenance burden for instrumentation tech and plant operators.

  7. UV System Provides Safe, Effective Disinfection For Wastewater Treatment Plant On The Hudson River

    The communities serviced by the Rensselaer County Sewer District, collectively known as the Albany Pool, have combined sewer systems (CSS) that bring stormwater, sewage and industrial wastewater directly to the wastewater treatment facility. When a storm or snow melt results in exceeded capacity, local waterways become contaminated, resulting in a significant environmental challenge, especially in a community where recreational swimming, boating and fishing are popular in warmer months.

  8. Safeguarding Public Health with UV Disinfection – Swansea, United Kingdom (Case Study)

    In order to improve the treatment performance (because of the continued cost to maintain compliance), and ensure that it would eventually have the treatment capacity to meet future population growth equivalent of up to 225,000,

  9. Activating The Sludge In Small Municipal Facultative Waste Lagoon Systems

    Wastewater treatment lagoons were originally facultative in design — shallow, single and multi-cell lagoon systems that counted on wind, sunlight, anaerobic bacteria, and time for the digestion of the organic components of the wastewater.

  10. BNR + MBR Equals Success At Water Reclamation Facility

    Biological Nutrient Removal (BNR) is allowing many wastewater treatment plants to achieve extremely high effluent quality. Still, for some applications even the most advanced BNR processes can’t address concerns with trace organics, pharmaceuticals, and other endocrine disrupting compounds (EDCs).
