PERSPECTIVES OF ELECTROCOAGULATION IN WATER DISINFECTION

Abstract

Today effective electrochemical disinfection system seems to be an alternative to conventional chlorination, ozone or UV processes. This paper reports on a series of experiments evaluating the disinfection efficiency of electrocoagulation cell using Al electrodes. Solutions contaminated by E. coli and surface waters were used as test media. The process significantly outperformed chemical coagulation reducing the amount of aluminum used. In all cases, the treated solutions were effectively disinfected and almost total removal of coliforms and algae were rapidly performed. A relationship for the disinfection rate of E. coli cells has been proposed. This equation takes into account the electrophoretic migration of the cells and the subsequent release of discharged cells into the bulk.
