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. Reservoir Overcomes Toxic Algae Issue
    6/16/2015

    A Nebraska reservoir was experiencing toxic algae in its water. Constructed by the U.S. Army Corps of Engineers (COE) primarily as a flood control reservoir with recreation and irrigation as secondary uses, the reservoir has a surface area of 700+ acres with an average depth of almost 12 feet.

  3. Microcystin Concentrations Following Treatments Of Harmful Algal Blooms
    6/16/2015
    Microcystin producing cyanobacteria blooms were sampled and tested from an Illinois reservoir, an Ohio reservoir and a Michigan lake.
    The Question: Should the fear of "releasing" microcystin deter an algaecide application?
  4. 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.

  5. Mountain Regional Water District Deploys Next Generation On-Site Hypochlorite And Tank Mixing Technology To Meet Expanding Water Management Needs
    7/16/2018

    The Mountain Regional Water District is a Special Service District of the county that was established by the Summit County Commission in 2000 to regionalize water service by consolidating several public and private water companies.

  6. On-Site Chlorine Generation Replaces Conventional Chlorine Gas Feed System In Scottsdale AZ
    12/25/2013

    The city of Scottsdale, Arizona, a community of more than 200,000 residents was historically totally dependent on groundwater resources.  By the mid 1980’s, the city began putting together a multi-faceted water resource program to provide the community with a long-term sustainable water supply.

  7. Coastside County Water District, California Drives System Reliability And Sustainability With Microclor® On‐Site Hypochlorite Generation, Encore® Metering Pumps And PolyBlend® Polymer Activation
    7/18/2018

    Located in northern California, the Coastside County Water District (CCWD) provides treated water to the scenic town of Half Moon Bay and several unincorporated communities in the area. The system is served by two treatment plants, the Nunes Water Treatment Plant (4.5 MGD) and Denniston Creek Water Treatment Plant (1.0 MGD) and water is distributed through about 100 miles of transmission and distribution pipe.

  8. 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.

  9. Safe Drinking Water With UV Disinfection (Case Study)
    11/13/2011

    The source water in Cudahy, a city just south of Milwaukee, is susceptible to contamination and significantly impacted by agricultural and urban runoff. After a Cryptosporidium outbreak in the early 1990s, improved water quality was vital. A UV solution proved to be the best fit for protection against the contaminant within a restrictive space.

  10. Largest Ozone Facility In North America Meets Regulatory Requirements And Remediates Taste & Odor Problems
    9/5/2018

    The North Texas Metropolitan Water District began working to add ozone to its four interconnected water treatment facilities which operate as the Wylie Water Treatment Plant (WTP).
