Purification of highly concentrated industrial sewage from the porcelain and faience industry by the electric flotation method

The mechanical methods of purification of industrial sewage generated in the porcelain and faience industry are considered. The expedience of using the electric flotation method with insoluble electrodes at the stage of separation of the solid and liquid phases using more effective flotation reactants is demonstrated. This makes it possible to shorten by several times the sewage treatment duration and to raise the degree of purification to 95 - 99%.[PUBLICATION ABSTRACT]
