Abstract
To efficiently perform an adhesion reduction treatment of water that circulates through a wet paint booth which contains a solvent-based paint by adding a relatively small amount of chemical to the water without the need for another chemical except that the alkaline chemical is used for pH adjustment, that is, with only one chemical. An aluminum salt having a basicity of 60% or more and an alkaline chemical are added to water that circulates through a wet paint booth which contains a solvent-based paint. An adhesion reduction treatment of the solvent-based paint is performed at a pH of 7 or more and is preferably performed at a pH of 7.5 or more. Using a powder mixture produced by mixing a powder of the aluminum salt with a powder of the alkaline chemical facilitates the treatment.
