ABSTRACT
Ozonization of drinking water is a process commonly used in France and Europe. Ozone is an excellent agent for the disinfection, oxidation of metals and organics, removal of taste and odors, removal of trihalomethane (THM) precursors to increase the biodegradability of organics prior to granulated activated carbon (GAC) filtration, etc. Though ozonization does not directly produce toxic organic by-products, some traces of bromide in water can lead to the formation of both hypobromous acid and hypobromide ion (bromine). These brominated entities can react subsequently either with organic substances or with ozone to form organobrominated compounds and bromate respectively.
