  5. Full-Scale Installation Report For Z-92® Uranium Removal – City Of Grand Island, NE
    8/7/2018

    A single WRT Z-92® Uranium Removal treatment system was selected by the City of Grand Island, NE to remove high concentrations of uranium in three city wells.  When the Z-92® Uranium Removal treatment system was installed in 2012, it was the largest uranium treatment facility in the nation. The high uranium in the raw water source is consistently being reduced to levels below the Maximum Contaminant Level (MCL). 

  6. General Electrochemistry
    7/28/2010

    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

  7. 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.
