    Municipality Removes Biofilm, Improves Water Quality, Lowers Dosage With MIOX

    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.

  • General Electrochemistry
    General Electrochemistry

    All chemical processes involve the loss, gain, or redistribution of electrons on an atom or group of atoms. Electricity is the movement of electrons along a conductor. It is no wonder then that chemical changes can be made to occur by passing an electric current through a solution containing atoms or groups of atoms which will accept or give up electrons. Processes which pass an electrical current through a solution to effect chemical changes are called electrochemical processes. By PEPCON Systems

  • Taste and Odor Treatment with UV-Oxidation - Mississauga, Ontario (Case Study)
    Taste and Odor Treatment with UV-Oxidation - Mississauga, Ontario (Case Study)

    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.

  • Performance Of A Conventional Surface Water Plant Using Mixed-Oxidants For Microflocculation And Final Disinfection
    Performance Of A Conventional Surface Water Plant Using Mixed-Oxidants For Microflocculation And Final Disinfection

    The surface water source is from snow-melt and summer thunderstorm run-off from the mountains. This water is detained in McClure Reservoir (7876 ft elevation) and Nichols Reservoir (7483 ft elevation) upstream from the CRWTP, a conventional plant built in 1974 with a design capacity of 8 MGD. Because the City has limited surface water rights, and due to decreased demand, the treatment plant usually shuts down for 60 to 90 days during winter. The reservoirs thaw in spring and turn over in autumn, and during the summer rainy season, raw water turbidities may exceed 5 NTU. By MIOX Corporation

ABOUT DRINKING WATER DISINFECTION

WATER DISINFECTION

Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.

Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
