ABSTRACT:
The invention discloses a composition and method for the enhancement of polyguanide based water sanitizing systems and for conversion of such systems to alternative water sanitizing systems if desired. The method includes the addition of an enhancing or conversion agent selected from the group consisting of a halogen salt, a Bromohydantoin and a chlorobromohydantoin in an amount to provide a concentration of approximately from 1 to 50 parts per million. Sodium borate and/or polyphosphate may also be added to the system to improve the effectiveness of the enhancing agent. The system may be converted to an alternative water sanitizing system by the addition of a sanitizing agent selected from the group consisting of chlorine, copper, silver, quaternary ammonium compounds, and polyquaternary ammonium compounds, which may be released into the water at a rate of 0.01 to 1 ounces per hour per 10,000 gallons of water for a period until conversion is complete.
