DEVICE FOR GALVANO-CHEMICAL PURIFICATION OF WASTE WATER Russian patent published in 2007 - IPC C02F1/463 

FIELD: purification of waste water.

SUBSTANCE: proposed device has vertical chamber with galvanic pair arranged in it and branch pipes for inlet of waste water and outlet of purified water. Chamber consists of two parts: upper part is provided with baffle made in form of truncated cone whose lower base is secured on upper rim of lower part of chamber. Guide side of taper baffle are made at angle of 55 to 65° relative to its base. Secured above baffle is casing made in form of truncated cone which forms together with baffle hydraulic seal system. Lower part of chamber is provided with ring-shaped disperser filled with particles of quartz and provided with branch pipe for pulsating of compressed air; inner diameter of disperser is equal to inlet hole of lower part of chamber. Device is also provided with intake unit for removal of floatation products and discharge of purified runoff.

EFFECT: low cost of process; enhanced efficiency of purification of waste water cations of heavy metals, anions of toxic metals and organic admixtures.
