  • Case study - CAIROX Potassium Permanganate

    BACKGROUND The Carbondale Water Treatment Plant (Carbondale, Illinois) with a design capacity of 8 MGD and an average flow of 4.6 MGD draws its water from Cedar Creek Lake. Because of moderately high raw water TOC levels (4.3 - 6.5 mg/L) and low alkalinity (36 - 40 mg/L as CaCO3), Carbondale is required to attain 45 percent TOC removal under the Disinfection/Disinfection By-Product ...
