Abstract

PURPOSE: To obtain treated water of a low dissolved salt concentration and of reuseability as washing water for the coating booth by coagulating water-soluble resin for removal by the addition of calcium sulfate to coating waste water.
CONSTITUTION: A coating waste water from the coating booth, polluted with water paint containing as vehicle components acid resins such as acrylic resins, alkyd resins, polyurethane resins, polyester resins, etc., is mixed with calcium sulfate of an amount more than one equivalent of the carboxyl group of the resin present in the waste water, preferably in a greater amount, in order to precipitate the resin content by coagulation. Then the resin is removed and the treated water so obtained is reused.
