Identification of Ozonation Products of Aromatic Hydrocarbon Micropollutants: Effect on Chlorination and Biological Filtration

Abstract

A study was made of the identification of substances produced by the ozonation of some aromatic compounds in a dilute aqueous medium: the aim was to determine the influence of ozonation on post–chlorination as well as on the mechanism of elimination of organic matter in secondary filtration on activated carbon. The nature of ozonation products such as aldehyde ketone and acid accounts for the following results –a change in chlorine demand and trihalomethane production –a loss in physical adsorption on activated carbon

–the significance of biodegradation in secondary filtration on activated carbon
