  1. Standardizing On-Site Hypochlorite Generation Disinfection Technology In Water And Wastewater Treatment Plants Increases Safety And Eases Operations
    10/3/2018

    In late 2005, the City of Newberg, Oregon, decided to upgrade their water treatment plant disinfection process from gas chlorine to on-site hypochlorite generation (OSHG) in an effort to simplify operations and increase operator safety. The plant produced an average of 2.5 million gallons per day (MGD), with a peak capacity of 5 MGD.

  2. Polymer Activation Equipment Upgrade Yields Consistent Polymer Savings Of Over 13%
    9/24/2018

    In an effort to lower operational costs and extend the life of the dewatering centrifuge, operators in Springboro, OH, began to look at the polymer activation equipment in use at the plant. The Polyblend® M-Series emulsion polymer activation systems had been in steady operation for over 10 years. The equipment still performed reliably, but operators were interested in ways to achieve greater efficiency. They were aware of the new Polyblend® Magnum mix chamber, with its enhanced two-zone mixing energy.

  3. Upgrading From Gas Chlorine To On-Site Hypochlorite Generation To Improve Safety And System Resilience
    9/20/2018

    By replacing gas chlorine with on-site hypochlorite generation, Nashville was able to improve the safety and longevity of its water plants to accommodate the growth of the “Heart of Country Music” far into the future. At a recent water conference, Glen Doss, Treatment Plant Manager stated, “In 2016, the last gas chlorine railcar left to large applause.” 

  4. Robust Encore® Pumps Replace Peristaltic Hose Pumps To Maintain Consistent pH For Finished Drinking Water
    8/22/2018

    Upper Deerfield Township, NJ relies on groundwater from four wells measuring 120 to 160 feet deep. The water is treated at two treatment plants with a capacity of 2.2 MGD and then pumped out to the distribution system with approximately 750,000 gallons of storage. Since the deep groundwater is hard, operators add lime to the finished water to raise the pH to reduce hardness.

  5. City Solves Wastewater Plant Dilemma With Dynablend™ Liquid-Polymer Technology
    8/6/2018

    The City of Marengo, Illinois operates an activated sludge wastewater treatment plant that processes an average volume of 1.8MGD with a maximum capacity of 5.94MGD. In the fall of 2007, the operators of the plant began to observe reduced performance of their liquid-polymer feed system that was in place at the city’s facility. The Dynablend™ liquid-polymer unit was a good fit for the Marengo plant because of its reliability and performance over a wide range of polymers commonly used for sludge processing.

  6. Australian City Installs Microclor On‐Site Sodium Hypochlorite Generation System
    7/24/2018

    Bathurst is the home of the Bathurst 1000 Race, the largest NASCAR-style “touring car” race in Australia. On race day, tens of thousands of additional visitors tax the capacity of the Bathurst 5 million-gallon-per- day wastewater treatment plant. The diligence and capability of the treatment staff allows the plant to meet the challenge every year. 

  7. The City Of Baxter Minnesota Installs And Starts‐Up An 800 Pound‐Per‐Day Microclor® On‐Site Hypochlorite System In Three Days
    7/24/2018

    The City of Baxter, located in central Minnesota, has always endeavored to deliver superior and reliable service to their customer base with a strong dose of selfreliance.

  8. Water Works Commission Lowers Risk Profile By Converting To A Safer Disinfectant
    7/24/2018

    Chatsworth Water Works Commission provides both water and wastewater services to the 5,000 residents of the cities of Chatsworth and Eton, GA.

  9. Hendersonville Water Treatment Plant Features Innovative Disinfection System
    7/24/2018

    Hendersonville Utility District (HUD) serves one of the most populous suburbs of Nashville, Tennessee.

  10. Utility Removes Burdensome Bulk Sodium Hypochlorite From Operations
    7/24/2018

    Historically, Lyon County Utilities, Nevada, applied 12.5% bulk sodium hypochlorite for disinfection at each of their well sites. Always looking to improve system efficiency, Lyon County staff reexamined on‐site hypochlorite generation to determine if the use of the 0.8% sodium hypochlorite solution could mitigate the challenges associated with dosing high strength sodium hypochlorite.
