APPARATUS FOR ELECTROCHEMICAL PURIFICATION OF SEWAGE Russian patent published in 2002 - IPC

FIELD: purification of sewage, electrodeposition, mechanical engineering, chemical, metallurgical industry. SUBSTANCE: apparatus for electrochemical purification of sewage has housing divided by partitions into electrode chamber, settling chamber and outlet chamber, union to supply starting and to discharge purified water and branch pipe for release of sediment. Electrodes of positive sign if soluble anodes are used and of negative sign if insoluble anodes are used are composite made of trapezoidal sectors put on horizontal rotary shaft. Immobile electrodes of opposite sign are placed between them. Immobile electrodes can be positioned in diaphragm chambers and settling chamber is equipped with belt conveyer. EFFECT: reduced overall dimensions, increased degree of purification of sewage, decreased usage of materials for manufacture of apparatus. 2 cl, 4 dwg
