Drinking Water Disinfection Resources

  1. Treatment of Groundwater Contaminated With 1,4-Dioxane - Tucson, Arizona 5/1/2019

    The TrojanUVPhox installation at Tucson's Advanced Oxidation Process Water Treatment Facility treats 1,4-dioxane and produces water that is blended and then treated at the neighboring Tucson Airport Remediation Project facility. 

  2. Automated Disinfectant Generation And Control Systems Produce Consistent Residual Levels In Aqua Pennsylvania's Distribution System 4/16/2019

    Aqua Pennsylvania (Aqua PA), an Aqua America subsidiary, serves more than 1.4 million people in 32 counties across Pennsylvania. Aqua PA has significant experience using chloramine chemistry to mitigate trihalomethane (THM) disinfection byproduct formation in its many distribution systems.

  3. City Of San Diego Water Plant Switches From Chlorine Gas To On-Site Hypochlorite Generation To Reduce Risks, Improve Safety And Decrease Costs 4/16/2019

    With virtually no local water sources available for use, the City of San Diego relies on water from the Metropolitan Water District, which imports its water from the Colorado River and the California State Water Project. The two massive water projects bring water from other watersheds and regions hundreds of miles to the north and east.

  4. A New Way To Kill Legionella 1/10/2019

    Advanced oxidation provides an all-in-one solution that supports the complete eradication of Legionella in a water system, while also preventing its regrowth.

  5. Akron's Path Toward An Intelligent Water Network Reduces Chemical Dosing While Improving Water Quality 11/8/2018

    When water demand declines, water quality and utility budgets can suffer. When the situation arose in Akron, OH, a smart solution emerged.

  6. A Multi Process Approach With One Single Solution 10/22/2018

    A joint effort between the city of Hollister, the San Benito County Water District and the Sunny slope County Water District, the group proposed the West Hills Water Treatment Plant (WHWTP) project to improve drinking water quality, water supply reliability, and to balance regional water resources in the Hollister Urban Area (HUA). Historically, HUA relied primarily on local groundwater basins for meeting their drinking water demands. While groundwater met all drinking water regulations, it is high in minerals and hardness that often resulted in scaling and the need for further conditioning.

  7. California Dreamin'? Pilot Study Makes Treating Arsenic, Manganese And Iron A Reality (Loprest) 10/12/2018

    A pilot study was conducted for arsenic, manganese, and iron treatment system at a well site. The onsite pilot test demonstrated the performance of the Loprest Water Treatment Company treatment process.

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

    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.

  9. Is Coagulation Followed By Filtration Viable To Remove Arsenic When Raw Water Arsenic Levels Are High? (Loprest) 10/9/2018

    A pilot study hoped to demonstrate "proof of concept" if coagulation followed by filtration was a viable technology to remove arsenic when raw water arsenic levels are high.

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

    A pilot study was conducted in Sacramento to provide manufacturers an opportunity to demonstrate the effectiveness of water treatment products that employ oxidation and filtration to remove iron, manganese, and arsenic to levels.
