Disinfecting Tablets 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 U.S. 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 six hours. When used as directed in any approved, gravity flow chlorinator, Bio-Sanitizer tablets provide positive disinfection and inhibit bacteria regrowth. Important: Septic chlorine tablets are NOT the same as swimming pool chlorine tablets. It is illegal to use swimming pool chlorine tablets because they are not approved by EPA or NSF for wastewater treatment. Acid based products, such as common swimming pool tablets, disinfect slowly and produce a non-degradable chlorine residual while lowering effluent pH. Even occasional use of these acid based products in wastewater treatment can result in the discharge of inadequately treated wastewater and create potentially harmful or hazardous gases. Pool tablets are designed to soak in water rather than just having water pass by them as in wastewater treatment. If improperly used in a wastewater treatment system, the pool tablets can emit hazardous gasses. This item is shipped UPS and is fully tracked and insured!
