THE USE OF RADIATION-INDUCED ADVANCED OXIDATION FOR WATER RECLAMATION

An advanced oxidation process (AOP) for water reclamation, particularl y groundwater remediation is described. It is based on a combination o f ozone and electron beam irradiation. Main pathways of the hydroxy fr ee radical generation in such a combination are reviewed and compared with those of other AOPs. New data is presented regarding the effect o f the direct introduction of gaseous ozone into the irradiation chambe r on pollutant decomposition, and the impact of the pH value on OH fre e radical production. Special attention is paid to an assessment of th e combined ozone/electron beam process in comparison to other AOPs. Co pyright (C) 1996 IAWQ.
