  • Significant Upgrades Enable City Of Atherton To Meet State’s DNR Discharge Requirements
    Significant Upgrades Enable City Of Atherton To Meet State’s DNR Discharge Requirements

    Built in the 1980s, Little Blue Valley Sewer District operates Atherton, which was designed to reduce the primary process chain to preliminary bar screening and aerated grit removal, while relying solely on secondary treatment performed in four, standalone 42-ft by 400-ft aeration/clarification basins. Read the full case study to learn how upgrading the activated sludge process with a combination of Xylem’s Flygt pumps and mixers created a solution for the city’s sewer district.

  • 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.

  • New Ultrasonic Flow Meters Improve Biogas Measurements

    As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.

  • Tradeshow Technical Session Leads To Significant Reduction In Polymer Use For South Carolina WWTP
    Tradeshow Technical Session Leads To Significant Reduction In Polymer Use For South Carolina WWTP

    Greer Commission of Public Works (CPW) has been providing water, wastewater and electric services to the City since 1914 with natural gas service added in 1957.
