Abstract

PURPOSE: To recover highly the performance of membrane by washing with an ether a permeable membrane to which contaminants adhere in order to remove the contaminants, said contaminants being formed by the treatment of liquid containing electrodepositing paints with the membrane.
CONSTITUTION: Contaminants which adhere to membrane are removed with an ether, after liquid containing electrodepositing paints is treated by using various membrane modules for a period. The membrane may be washed with an alcohol or with an alcohol and an ether. Examples of ethers include methyl cellosolve, ethyl cellosolve, etc. Examples of alcohols include methanol ethanol, etc. An ethr solution having a concentration of above 10% and an alcohol solution having a concentration of above 30% are articularly effective. The performance of the membrane can highly be recovered by this washing without producing a bad effect on the membrane material or an effect on the electrodepositing paints and painting stage.
