Drinking Water Disinfection [Case Studies White Paper]

  1. Technical Support And Service Are Key In A Place “Way Outside Of Ordinary”
    3/20/2018

    Rangely is a remote town with a population of just over 2,200 people located in the upper northwest area of Colorado, thirteen miles from the Utah border. During the course of their routine maintenance, operators noticed problems with a distribution pump. Read the full project profile to learn how Process Solutions’ trained service technicians were able to walk them through a series of diagnostics to further isolate the problem and get the system was back up and running in a short period of time.

  2. Treatment Of Cyanotoxins In Drinking Water With Activated Carbon
    9/24/2014

    Recently, cyanobacteria and cyanotoxins have become a high profile drinking water quality concern in both the United States and abroad. The combination of weather conditions, agricultural phosphate runoff, and other factors has produced water conditions that have favored the formation of cyanobacteria in surface water supplies.

  3. Dissolved Air Flotation System Reduces Costs, Improves Process
    3/1/2015

    With the town of Johnstown, CO's, water treatment plant began operating its circular clarifier systems at maximum capacity to meet summer peak demand rates, consultants recommeded increasing plant capacity and using dissolved air flotation technology for their clarification process.

  4. Direct Filtration Of Spring Water
    10/23/2012

    The Franklin Water Treatment Plant, near the Utah/Idaho state border, serves approximately 600 residents. Traditionally, water was drawn from springs and chlorinated.

  5. Taste and Odor Treatment with UV-Oxidation - Mississauga, Ontario (Case Study)
    7/7/2010

    The Region of Peel is the second-largest Canadian municipality after the city of Toronto, and draws its drinking water from Lake Ontario — the smallest of the five Great Lakes. To meet the projected population increase from 1,160,000 people currently to an estimated 1,571,000 people in 2031, the Region decided to upgrade and expand its water treatment plant. To deal with seasonal taste and odor compounds produced by algae blooms in Lake Ontario, the membrane plant will be equipped with a Trojan UV-Oxidation system.

  6. UV Disinfection Eliminates Groundwater-Borne Pathogens At Water Utility
    3/13/2015

    A study led by the Marshfield Clinic Research Foundation set out to prove the growing evidence 'that our groundwater is fairly heavily contaminated with human pathogenic viruses.'

  7. City Of Springfield, MO, Upgrades Disinfection System From Gas Chlorine To On‐Site Sodium Hypochlorite Generation
    8/15/2016

    In April 2013, City Utilities started up three Microclor Model MC‐1500 skid systems, each rated at 1,500 pounds per day of free available chlorine.

  8. Generating Disinfectants From Water: Could In Situ Electrolytic Production Be The Future?
    3/31/2014

    Chemical disinfection using strong oxidants involves the transportation, storage, and handling of unstable and/or aggressive and hazardous chemicals. The production of oxidants at the location where they are to be used has therefore been a preferred option, especially in small-scale or remote installations. On-site electrolysis of NaCl for the local production of chlorine or hypochlorite, or the production of ozone-enriched oxygen by silent discharge has been standard for years.  However, it is possible to take the idea of producing chemical disinfectants locally a step further and look at in situ techniques, i.e. at devices, which produce oxidants in and from the water to be treated.

  9. Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility
    5/1/2017

    The North Columbus Resource Facility recently completed a $12-million replacement of its settled water filtration, removing the existing Wheeler filters, their three-part media and 10-inch poured concrete underdrains, which were no longer efficient.

  10. Municipality Removes Biofilm, Improves Water Quality, Lowers Dosage With MIOX
    3/27/2014

    Looking to reduce potential disinfection byproducts issues that new and difficult regulations were requiring, a Tennessee municipality began investigating alternative water treatment disinfection methods in an effort to reduce the potential liability (RMP) involved with using and storing gas chlorine. Within months of switching to a mix of oxidants (MOS), a difference was noted in the systems residual, residual was no longer dead spotting in low flow areas, and much higher residual was noted in areas that had been difficult to maintain At the end of the first year of operation the municipality had also documented a reduction in their disinfection byproducts formations, specifically both TTHMs and HAAs, which were both reduced by 50% in direct comparison with the quarterly results from the previous year.
