Drinking Water Disinfection [Case Studies White Paper]

  1. Encore® 700 Chemical Metering Pumps Provide SNWA With A Decade Of Flawless Service At River Mountains
    8/15/2016

    Built in 2002, Southern Nevada Water Authority’s (SNWA) River Mountains Water Treatment Facility is a state-of-the art  water treatment facility that delivers 300 million gallons per day and was designed to be expanded to deliver up to 600 million gallons per day of treated water in the future.

  2. Benefits And Disadvantages Of The Advanced Oxidation Process
    6/27/2019

    In many water and wastewater treatment applications, there are a number of pollutants that are difficult to reduce by physical, chemical, or biological means alone. In more recent years, there has been a growing concern regarding pharmaceutical drugs in drinking water and aquatic environments. Pesticides get caught in runoff from farms into freshwater supplies. 

  3. General Electrochemistry
    7/28/2010

    All chemical processes involve the loss, gain, or redistribution of electrons on an atom or group of atoms. Electricity is the movement of electrons along a conductor. It is no wonder then that chemical changes can be made to occur by passing an electric current through a solution containing atoms or groups of atoms which will accept or give up electrons. Processes which pass an electrical current through a solution to effect chemical changes are called electrochemical processes. By PEPCON Systems

  4. City Solves Reliability And Maintenance Problems For WTP Hypo Feeds
    8/13/2014

    A municipal water quality manager reports replacement of sodium hypochlorite (hypo) vacuum feeder units with a more advanced type at one water treatment plant (WTP) has helped allow for continued reliability for chlorination.

  5. Midlothian, TX, Expands Water Treatment Plant With A Safe, Reliable Disinfection System
    7/24/2018

    When the City of Midlothian, Texas, was ready to expand their water treatment plant to accommodate a growing population, they carefully considered and investigated their water disinfection options.

  6. Removing Iron, Arsenic and Manganese To Meet California Regulations
    10/9/2018

    Water from Well 19 and 20 in Sacramento, California area was high in manganese and arsenic. Due to the high levels, the wells were not being used to supply municipal water to the District. Each facility is planned to initially produce and treat approximately 600 gpm with a future expansion capacity to 1200 gpm.

  7. 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.

  8. Color Reduction From RO Concentrate
    3/3/2015

    The City of Palm Coast, FL was experiencing elevated color in the concentrate stream being directed to the lime softening facility to recover as drinking water. In an effort to meet secondary color standards at the lime plant, this water quality issue limited the volume of the concentrate able to be recovered.

  9. Filtration Avoidance in Surface Water - North Tahoe, California (Case Study)
    11/30/2011

    With its mountain beauty and deep, clear waters, Lake Tahoe is one of the most popular vacation spots in the California/Nevada area.

  10. 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.
