Abstract

A process and a device for the treatment of water, especially for removing therefrom a large variety of pollutants, especially organic, inorganic and biological pollutants through in situ generation of ozone. Ozone is economically produced in situ at a high concentration through the interaction of electrolytically produced oxygen and UV light having a wavelength of 189 nm. The device has a set of anode and cathode for electrolytically producing nascent oxygen which reacts with UV light at a wavelength of 189 nm to produce ozone "in situ " within a vessel where the polluted water is submitted to the combinative action of ozone and other oxidation reactions. The device also has a hydrocyclone or retention tank of removing cationic pollutants such as heavy metals, free radicals as well as undesirable electrolysis by-products such as nascent hydrogen through a secondary outlet. Oxidation by-products are subsequently removed from the exiting water stream by means of decantation, flocculation, coagulation or filtration.
