ABSTRACT:
A process for purifying tap water which comprises filtering water containing impurities flocculated by a metal hydroxide produced electrolytically, through a layer of a solid water-insoluble granular material. On said layer, in the direction of water flow, a layer of a metal hydroxide is deposited through which the water to be purified is passed. The water thus purified is substantially free from impurities and may be useful in the electronics, medical, food and other industries.
