A disinfection composition comprising an oxidising biocide and a delayed release biocide quencher

Abstract

The invention relates to a composition and a process for disinfection, and particularly for purification of contaminated water. The invention is especially useful for removal of suspended impurities and harmful microbial contaminants like bacteria, viruses and cysts from water to make it healthy and palatable for human consumption. The invention provides a disinfection process and composition, the composition comprising an oxidising biocide and a delayed release biocide quencher, comprising an anion which is a reducing agent.
