Abstract

PURPOSE: To save washing water and prevent discharging of water contg. high- concn. boric acid by subjecting the waste water produced in electrolytic coloring process of aluminum or the like to reverse osmosis membrane treatment then performing boric acid removing treatment of the permeated water thereof.
CONSTITUTION: An aluminum material 1 to be treated having been colored in an electrolytic coloring bath tank 2 is washed in washing tanks 3, 4, the waste water whereof is controlled of pH in a pH control tank 6 through piping 5, after which it is pressurized by a high-pressure pump 10 via a filter 9 and is supplied to a reverse osmosis device 11. The permeated water from the membrane of the device 11 is lowered of its boric acid concn. by way of the boric acid removing devices 18, 18' after which it is reused as the washing water for the tank 4. On the other hand, the concd. water of reverse osmosis is released of pressure in a pressure holding valve 12, after which it is passed through colored harmful component removing columns 16, 17, and is returned into the tank 2. It is equally well to recover nickel in the electrolytic treatment process without returning the concd. water of reverse osmosis.
