Non-Oxidative Chlorine 200 times more effective at removing the environment for coliform bacteria in wells and pipelines. STERILENE is a sodium based, granular chlorine that does not require a control of pH using vinegar or acid to make it effective. It is far more effective than any other standard chlorine (liquid sodium hypochlorite or calcium hypochlorite) at a competitive price. This means a lower cost, no premixing, and far less failures. Benefits of using Sterilene 55% available chlorine Granular but easy to mix, even in cold water No premixing to control pH No corrosive fumes No shelf life limitations Easy to use Long-lasting Specifications: Base Materials: Sodium based / Granular Chlorine Certifications: NSF 60 Certified TDS SDS PDS
