Bio-sanitizer disinfecting tablets are specially formulated to provide safe, efficient and reliable disinfection of water or wastewater flows. Bio-sanitizer tablets provide treatment plant operators a consistent way to meet disinfection standards without exceeding stringent limits for total residual chlorine. Registered by the US environmental protection agency and the Canadian ministry of the environment, bio-sanitizer tablets are a preferred, safe alternative to dangerous liquid and gas disinfection systems. Bio-sanitizer tablets insure reliable disinfection rates up to intermittent peak flow factors of four and maintain a uniform chlorination rate even when the significant runoff period is 6 hrs. When used as directed in any approved, gravity flow chlorinator, bio-sanitizer tablets provide positive disinfection and inhibit bacteria regrowth.
