  • Case study - Floating covers reduce TSS, improve chlorine disinfection

    Problem: Algae and ultraviolet (UV) rays were adversely affecting chlorination in an upstate New York reservoir and Southern Florida WWTF. Algae was shielding embedded bacteria from chlorine, making the bacteriacide ineffective, thus requiring the chlorine dosage to be increased. Algae increased the chlorine demand along with exposure to UV which dissipates un-stabilized chlorine. Both ...
