Modelling of Micropollutant Removal by Ozonation and Chlorination in Potable Water Treatment

In regards of increasingly stringent rules on toxicity, prediction engines for potable water treatment have become a necessity. This particularly applies to oxidation steps, where micropollutants should be removed and where potentially harmful by-products may be formed, and has therefore lead to the building up of a new simulator for both chlorination and ozonation. This first report aims at giving a clear overview on the investigation fields related to modelling of oxidation for water purification. Different aspects are thus developed in the following pages. Besides kinetics and hydraulics, special topics on informatics and applied mathematics are discussed as well, presenting simulators that exist and specific calculation procedures. The originality of the modelling lies namely in its adaptability to on site conditions, which implies specific numerical methods to be implemented. Basing on the bibliographic review (illustrated by first numerical examples), the present work finally will exhibit the challenges to be faced during development.
