Abstract
PURPOSE: To remove contaminants adhered to a permeable membrane by bringing the permeable membrane used in the treatment of a liquid containing anionic electrodeposition paint into contact with a mixture of water, a water-compatible solvent and an amine in specific proportions.
CONSTITUTION: A permeable membrane, such as noncellulosic membrane, e.g. of synthetic resin (e.g., hydrophilic polyolefin), etc., is treated for removing contaminants adhered by using a mixture composed of 100pts.wt. water, at least 1.0pt.wt. an organic solvent compatible with water, and 3.0W50pts.wt. an amine of a molecular weight of 157 or less. In this case, the use of the amine of a molecular weight of 157 or less is important by the reason that amines of 157 or more molecular weights are hardly soluble in water and thus deteriorate the removing effect of contaminants on the membrane.
