Drinking Water Filtration Case Studies and White Papers

  1. Ozone System Delivers For Miramar Water Treatment Plant Upgrade And Expansion Project
    8/15/2015

    A combination of growing demand, aging infrastructure and regulatory requirements acted as drivers for a new ozone system at the Miramar Water Treatment Plant in San Diego, CA.

  2. Turbiwell Comparision Report Before And After Upgrade
    7/29/2015

    Russellville water treatment plant is a surface water plant using traditional clarification, filtration, and treatment. The plant historically has used traditional contact turbidimeters that employ tungsten lamps that required quarterly maintenance, but replaced their turbidimeters with Swan Turbiwell turbidimeters in 2012. Read the full report for a comparison of the performance of the Swan Turbiwell to the previously installed turbidimeters. 

  3. A New Way Of Designing With Reverse Osmosis Membranes
    7/23/2015

    Process design in water treatment is historically confined to proprietary or user-defined spreadsheets on a unit operation basis, with users manually adding results from each unit process upstream into the next operation.

  4. Ozone Disinfection System Provides Treatment In Arizona
    6/19/2015

    Water is disinfected before it enters the distribution system to ensure that dangerous microbial contaminants are killed.

  5. Ozone Disinfection System Provides Second Stage Treatment For Water Treatment Plant
    6/19/2015

    Tampa Bay Water’s state-of-the-art surface water treatment plant has provided high-quality drinking water to the Tampa Bay region.

  6. UV Disinfection And Ozone Oxidation In Tandem
    6/5/2015

    Located 30 minutes North-East of Montreal, Canada, the City of Terrebonne has the last drinking water intake of the many cities along the Rivière des Milles-Iles.

  7. Generating Station Maximizes Efficiency By Choosing A Membrane Decarbonation System
    6/1/2015

    When dissolved carbon dioxide in the water began overloading the anion resin and decreasing capacity at its Rokeby Generating Station, Lincoln Electric Systems had to act quickly to update its winter contingency plans and meet increasing demand. In this case study, learn why the municipality chose a membrane degasifying system over chemical treatment options or a forced draft aerator, thus reducing costs and improving overall efficiency by minimizing downtime.

  8. Membrane Treatment Of Groundwater
    4/2/2015

    The groundwater that a southern Louisiana water utility supplies to local residents has traditionally carried a high amount of organic material and color. In the past, the organics were oxidized and broken down by chlorination, but this practice had gone out of favor due to production of disinfection by-products (DBPs) such as Trihalomethanes (THMs) and Haloacidic Acids (HAAs).

  9. New Membrane Technology Handles High Solids, Aids Water Reuse
    2/18/2015

    As global conditions place more stress on water resources, a great deal of attention is being paid to water reuse technologies, particularly those that facilitate the reuse of the next level of difficult-to-treat or highly variable raw water sources.

  10. Integration Of Membrana Ultrafiltration And Gas Transfer Membrane Technologies Produces High Quality Water And Controls Corrosion In Cooling Water System
    2/11/2015

    By incorporating Membrana UF and Gas Transfer Membrane (GTM) a resort customer was able to reduce the risk of contaminating its cooling water and protect other system components from corrosion. The compact systems exceeded performance expectations and reduced maintenance and operating costs while maximizing the available space.
