Odor Control Case Studies and White Papers

  1. Five Years Of Post-Aeration At A Wastewater Treatment Plant
    5/28/2015

    To protect the environment, wastewater treatment facilities across the country are required to deliver dissolved oxygen (DO) into the treated effluent, with most DO permits ranging from 2 to 10 mg/L.

  2. North Carolina Treatment Plant Eliminates Taste And Odor Issues With Ozonation
    3/9/2015

    Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), Cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public.

  3. Wastewater Treatment System Achieves Stringent Water Quality Discharge Limits And Reduces Costs
    3/9/2015

    The Village of Johnson Wastewater Treatment Facility (WWTF) was among the first in the state of Vermont to meet newly enacted secondary treatment requirements when it began operation in 1970.

  4. Mixers Prevent Buildup And Reduce Wetwell Cleaning Charges
    3/9/2015

    The City of Reno, NV, has long battled the buildup of fats, oils, and grease in the wetwells of wastewater lift stations in the valleys within this high desert city. Recently, the city set out to address the problem and reduce the associated costs.

  5. Pilot Studies In North Carolina With Hydrex™ Odor Solutions
    10/17/2014

    Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

  6. WWTP Overcomes Odor Issue
    5/28/2014

    The City of Crystal Lake is located about 45 miles northwest of Chicago with a population of nearly 45,000 people. Like many wastewater treatment plants, urban sprawl and suburban development puts the Crystal Lake Wastewater Treatment Plant near a host of commercial and residential neighbors, including a high school immediately west of the plant. Plant managers were very forward thinking, and wanted to be good neighbors to those occupying the surrounding area. They wanted to take steps to reduce — and hopefully eliminate completely — any odor issues from the plant.

  7. A New Paradigm In Aeration Technology
    5/13/2014

    The DO2E organization sprang from one individual’s attempt to solve an aeration problem in a fish hatchery and realizing that his device to do so had many other applications as well. This device broke up algal blooms as well as aerating, and it was only a short step to modify it into breaking up FOG (fats, oils, and grease) deposits in grease traps and lift stations. This device was patented, thus DO2E was born.

  8. Odor Control For The City Of Houston
    9/16/2013

    A supersaturated side-stream process (SDOX-CS®) was successfully deployed at temporary and permanent locations throughout the City of Houston for the effective control of collection system odors.
