We have studied treatment of chromium - containing wastewater. The purity of the chromium- containing wastewater by liquid Memhrare (L. M) technique can come up to the drainage standards. The solusion of concentrate of chromium can be recovered. The solusion of concentrate have been used into Zine passivating and chromium-plating. Thus, CrO3 in the wastewater can be retrieved. It solve a probem of pollution and save rawmaterials and funds.
