Drinking Water Disinfection [Case Studies White Paper]

  1. Product Recovery Through Ozone Oxidation Of Waste Liquor
    9/15/2018

    The manufacturing of soda ash from Trona is a multi-step process that results in the production of a waste liquor that contains significant levels of organic contamination.

  2. Removal Of Disinfection By-Product With Chlorine Dioxide
    8/9/2016

    This municipality disinfects 1-1.5 million gallons per day of drinking water, and is currently transitioning from a small system serving <10,000 people to a large system serving >10,000 people. Chlorine gas was used as the primary disinfectant for the raw water entering the plant.

  3. Dissolved Air Flotation System Reduces Costs, Improves Process
    3/1/2015

    With the town of Johnstown, CO's, water treatment plant began operating its circular clarifier systems at maximum capacity to meet summer peak demand rates, consultants recommeded increasing plant capacity and using dissolved air flotation technology for their clarification process.

  4. Monitoring Water Quality With UVC LEDs
    11/2/2015

    Rapid detection of changes in water quality is critical in water delivery systems, wastewater treatment, and industrial plants for process optimization, environmental regulatory requirements, and consumer health.

  5. Ozone Resolves Hydrogen Sulfide And Color Issues In Well Water
    9/1/2018

    A potable water plant in Eastern Angelina County, Texas,  serves over 2,000 rural customers.

  6. Direct Filtration Of Spring Water
    10/23/2012

    The Franklin Water Treatment Plant, near the Utah/Idaho state border, serves approximately 600 residents. Traditionally, water was drawn from springs and chlorinated.

  8. California Mountain Town Cuts Salt Use, Doubles Disinfection
    1/24/2011

    The wastewater treatment facility of the remote mountain resort community of Pinecrest Lake bears the brunt of spring runoff and increased summer demands in the area's beautiful surroundings.

  9. Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69%
    9/10/2018

    The financial cost to maintain their ozone equipment, and increasing scarcity of replacement parts for their ozone generator, motivated a utility in Springfield, MO, to upgrade their ozone system. Read the full case study to learn how the plant assessed the energy cost of a sidestream ozone injection system compared to that of a turbine mixing design and showed that the Mazzei retrofit design reduced the energy cost of ozone contacting by an average of 69.2% under all plant flow conditions.
