Uses of ozone in drinking water treatment

Abstract

Ozone has been used continuously for the treatment of drinking water since 1906, when it was first installed in the city of Nice, France, for disinfection purposes. Although many water treatment plants throughout the world still utilize ozone primarily for disinfection, most modern plants rely on ozone to perform one or more oxidation functions. Applications for ozonation now include oxidation of inorganic and organic materials, flocculation and microflocculation for removal of turbidity or suspended solids, and, recently, promotion of aerobic biological processes conducted in filter and adsorption media.
