Multi-functional oxidizing composition

Abstract

A composition comprising a stable anhydrous mixture of an oxidizing agent and an active halogen agent wherein the oxidizing agent is potassium hydrogen peroxymonosulfate and the active halogen agent is an alkali metal salt of dichloro-s-triazinetrione, halogenated dimethylhydantoin, or mixtures thereof, and a method of treating water with such compositions are disclosed.
