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 H2 (8) generated in the cathode space (6) o

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 H2 (8) generated in the cathode space (6) of the same cell (3) or H2 (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.

A process for purifying water, comprising the steps of: (i) electrolizing water in an electrochemical cell provided with a solid elecrolyte, an anode space and a cathode space, to form ozone in said anode space and hydrogen in said cathode space; (ii) contacting said water with said ozone for suffic

A process for purifying water, comprising the steps of: (i) electrolizing water in an electrochemical cell provided with a solid elecrolyte, an anode space and a cathode space, to form ozone in said anode space and hydrogen in said cathode space; (ii) contacting said water with said ozone for sufficient time to break down any organic substances and microbes in said water to obtain an ozone treated water; and (iii) contacting said ozone treated water with a portion of said hydrogen generated in said cathode space.
