Abstract
A process for breaking down organic substances and/or microbes in pretreated feed water for high-purity recirculation systems using ozone which is generated in the anode space (5) of an electrochemical cell (3) and treated with ultraviolet rays and/or with H.sub.2 (8) generated in the cathode space (6) of the same cell (3) or H.sub.2 (20) supplied from outside. The latter is used to reduce elementary oxygen in any form to harmless water. Post treatment via mixed bed (14) and filter (15). Possibility of feeding back water (19) downstream of the receiver (17). No harmful reaction products.
