  • Process for treatment of waste water exhausted from water-wash spray booth using water-soluble paint
    Patent number: 4071449
    Abstract: A process for treatment of waste water exhausted from a water-wash spray booth using a water-soluble paint which comprises adding an acidic agent and an alkaline agent, which can form a salt insoluble or hardly soluble in water as the result of the interaction between them, to the waste water while keeping its pH value in the range of about 6 to 9 so as to cause the water-soluble paint to be deposited as a non-adhesive coagulation product and eliminating the non-adhesive coagulation product from the resultant waste water by a conventional procedure for separation of solid and liquid.
