Contaminant Removal Case Studies and White Papers

  1. Basin Nozzle Manifold Contacting System Installation Remediates Taste And Odor Compounds, Meets Disinfection Goals
    9/1/2018

    A water quality audit revealed that two of the largest drinking water plants in the City of Montreal were out of compliance with Quebec’s latest water quality rules. Both drinking water facilities were located in heavily populated areas; consequently, plant modifications had to be accomplished within their existing infrastructure footprints.

  2. Bulk Hypochlorite Disinfection System Replaced With On-Site Hypochlorite Generation System Saving About $160,000 Per Year In Materials
    7/18/2018

    Originally built to treat 10 million gallons per day (MGD), the Quail Creek Water Treatment Plant in Washington County, Utah, now has an operational capacity of 60 MGD and a design capacity of 80 MGD.

  3. Evaluation Of Ceralite-A As An Alternative To Anthracite Filter Media
    5/25/2018

    The Golden Heart WTP located in Fairbanks Alaska is a lime softened, ground water treatment plant with five filter basins, with a combined surface area of 1495 ft2 . Typical filter loading rates are in the 2.3 –to 3.1 gpm/ft2

  4. Cheyenne Board Of Public Utilities In Cheyenne, Wyoming Successfully Moves From Calcium Hypochlorite Tablets To Microclor® On-Site Hypochlorite Generation
    7/24/2018

    The Cheyenne Board of Public Utilities (BOPU) operates the water and wastewater systems for the capital of Wyoming which has a population of more than 63,000. Located in the fast growing Front Range Urban Corridor, BOPU is challenged by growth, periodic water scarcity and aging infrastructure.

  5. 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.

  6. Full-Scale Installation Report For Z-88® Radium Removal – City of Bridgeton, NJ
    8/14/2018

    WRT’s Z-88® Radium Removal treatment system was selected to remove high concentrations of radium in two treatment facilities for the City of Bridgeton, NJ.  Both treatment facilities are now producing safer drinking water since the installation of the Z-88® Radium Removal treatment systems in 2009 and 2010.

  7. Pilot Test For Manganese Removal Using Manganese Greensand
    10/11/2018

    Loprest has been designing and fabricating manganese removal systems using manganese greensand for over forty years. Drawing on that experience; filtration rates, run times, backwash procedures, chemical dosage rates, etc. are all established by theoretical calculations and history. Therefore, Loprest’s goal in this pilot study was to conduct uninterrupted operation per bid testing procedures and document the results.

  8. Top Research Institute Turns To On-Site Generation For Drinking Water System
    9/18/2018

    As one of the top 20 American research institutes in the United States, Texas A&M has hundreds of laboratory facilities on its campus where a variety of proven water treatment technologies are used to control the quality of the water used in research.

  9. Removing Hexavalent Chromium From Groundwater Supplies
    8/14/2018

    The chromium removal pilot study was conducted for the County of San Bernardino, CA at their CSA 70 Zone J - Well 5 treatment facility. Chromium in the CSA 70 Zone J – Well 5 raw water source exceeds the current Maximum Contaminant Levels (MCL).

  10. Iron, and Manganese Arsenic Pilot Study In The Golden State
    10/1/2018

    This report summarizes results and conclusions of a groundwater treatment pilot test program. This pilot test program was undertaken to demonstrate the effectiveness of water treatment products that employ oxidation and filtration to remove iron, manganese and arsenic to levels well below MCL’s. Operating data collected during the study will be used to confirm the design of fullscale facilities.
