Abstract
Procédé de traitement d'eaux par addition d'un oxydant formé d'ozone. Le traitement à l'ozone s'effectue à un pH d'au moins 8,5, le pH étant réglé par exemple par addition de produits chimiques ou par passage sur une matière granulaire dont la surface est de nature à élever la basicité ou à l'aide de catalyseurs d'oxydation de nature à élever la basicité ou encore à l'aide d'échangeurs d'anions qui créent une basicité. Application au traitement des eaux de surface ou des eaux souterraines dans la production d'eau potable.Process for treating water by adding an oxidant formed from ozone. The ozone treatment is carried out at a pH of at least 8.5, the pH being adjusted for example by adding chemicals or by passing over a granular material the surface of which is such as to increase the basicity or using oxidation catalysts such as to increase basicity or even using anion exchangers which create basicity. Application to the treatment of surface water or groundwater in the production of drinking water.
