Abstract

Water is purified by submitting it to on electro-oxidation, which produces purifying products, then to an electro-reduction of these products, followed by filtration. A rest phase is pref. introduced between the electro-oxidation and the electro-reduction to allow the purifying products to take effect. The electro-oxidn. cell is fitted with insol. and unoxidisable electrodes, partic. of Pt or graphite, the water being fed in a continuous process. The electro-reduction cell contains soluble electrodes, partic. of Fe or Al. Used partic. for the treatment of sea water contaminated with pathogenic germs from faeces, and also be used to decontaminate shellfish without adversely effecting them biologically or affecting their taste, the germ-destroying products produced during electro-oxidation being removed during electro-reduction before the water is passed back to the shellfish.
