Abstract RU 2088537 C1

FIELD: waste water treatment. SUBSTANCE: method consists in that waste water from galvanic production washing is submitted to mechanical filtration and then to reverse-osmosis separation to yield filtrate and concentrate. Filtrate is returned into washing stage and concentrate into electrochemical metal isolation stage. According to invention, 99% of filtrate based on waste water volume is returned into washing stage, and 1% of concentrate based on waste water volume is directed into electrochemical metal isolation stage.
