ABSTRACT:
The invention concerns a process and apparatus for the preparation of a disinfectant for water, such as drinking- or swimming-water by electrolysis of an aqueous NaCl-containing solution.
In order to improve these, the process of the invention is characterized in that an NaOCl-containing solution obtained by electrolysis is enriched with electrolytically obtained Cl.sub.2 by either electrolytically preparing an aqueous NaCl and NaOCl-containing solution and further electrolyzing said solution to partially convert the Nacl still present therein into Cl.sub.2, or electrolytically preparing a mixture of an aqueous NaCl solution and Cl.sub.2, and further electrolyzing said mixture to partially convert the NaCl still present therein into NaOCl.
The apparatus of the invention is characterized by a combination of a first electrolytic cell (1) and a second electrolytic cell (2), which are electrically series-connected, said first electrolytic cell (1) being provided with a brine supply line (8) and a discharge line (10,11) and comprising a plurality of pairs of electrodes (A1, K1. . . A5, K5), no separation being present between the anode and the cathode of each pair of electrodes, and said second electrolytic cell (2) comprising one or more pairs of electrodes (A6, K6), a diaphragm or ion-selective membrane (5) being positioned between the anode (A6) and the cathode (K6) of the or each pair of electrodes, in which second electrolytic cell (2) the anode space(s) (6) is (are) connected to the discharge line (11) of the first electrolytic cell and to a product discharge line (15) , and the cathode space(s) (7) is (are) provided with a supply line (12) and a discharge line (13,14).
