  • Wastewater Facility In Missouri Tackles Foul Wastewater Treatment Odors Safely And Effectively
    Wastewater Facility In Missouri Tackles Foul Wastewater Treatment Odors Safely And Effectively

    Serving nearly 16,000 customers, a large-scale wastewater treatment facility in Missouri manages a complex sewer system, and has to contend with regional growth where more residential houses and commercial facilities have been built close to the facility. As a result, foul odor complaints from neighbors continue to increase, and the local town council found itself in need of fully addressing this issue.

  • Easy To Digest: H<sub>2</sub>S Removal Rids City Of Lift Station Odors
    Easy To Digest: H2S Removal Rids City Of Lift Station Odors

    A constant problem in many wastewater collection systems is the formation of hydrogen sulfide (H2S) in the lift stations as well as from biofilms further downstream in the delivery piping to the wastewater treatment plant. DO2E representatives suggested that the City of Taylorville (IL) use their proprietary digesters equipped with an ozone (O3) capability to remove this problem from our system.

  • Mapping And Identifying The Source Of Water Quality Issues
    Mapping And Identifying The Source Of Water Quality Issues

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  • Solar-Powered Circulators Turn Around WWTP Lagoon’s Issues
    Solar-Powered Circulators Turn Around WWTP Lagoon’s Issues

    For years, the wastewater treatment plant in Villa Mercedes, David City, Panama emitted harsh odors and created a rampant mosquito population, a situation the neighboring residents found impossible to deal with. Treatment at the plant needed improvement to successfully treat up to 4.6 million gallons of wastewater per day, eliminate harsh odors and reduce the mosquito population.

  • WWTP’s Screw Press Reduces Odors, Saves Money, And Takes Up Less Physical Space
    WWTP’s Screw Press Reduces Odors, Saves Money, And Takes Up Less Physical Space

    A WWTP chooses a new screw press that takes up less than half the space that the old belt press had occupied. This was striking for the operations team but not as striking as the fraction of time they needed to spend managing the screw press.

    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.

  • Targeted Algal Management Plan To Address Taste And Odor Problem
    Targeted Algal Management Plan To Address Taste And Odor Problem

    Lake John Hay is located six miles northwest of Salem, Indiana and is used for drinking water and tournament and recreational fishing. With an average depth of 14-15 feet, it is ideal for algae and plant growth. The persistent, recurring algae blooms was causing taste and odor problems, which led to frequent complaints.

    Aeration And Mixing Solutions For Freshwater Remediation

    FluenceTORNADO® Self-aspirating surface Aerators and submerged Diffused Air Systems helped to rejuvenate the Laguna Niguel fresh water reservoir in Southern California. The aerators removed the algae and odor problems naturally, and kept the oxygen content of the water high enough to support a profitable fishing industry.

Five Years Of Post-Aeration At A Wastewater Treatment Plant
Five Years Of Post-Aeration At A Wastewater Treatment Plant

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.
