Abstract
PURPOSE: To adsorb and remove the impurities such as inorganic ion in the liquid and to stably perform the electrodeposition painting operation by separating the electrodeposition painting bath liquid or its concentrated liquid into concentrated liquid and membrane permeated liquid by the filter membrane, and contacting said permeated liquid with the adsorption medium.
CONSTITUTION: A part of a paint for electrodeposition painting 1 in a subtank A is sent to a reverse osmotic membrane apparatus D under pressure and is separated into concentrated liquid of membrane side 3 and membrane permeated liquid 2. Said liquid 2 is sent to the second flushing vessel C-2 and painted article from the first flushing vessel C-1 in front is washed by the liquid 2. That is, the article to be painted is washed in the vessels C-1, C-2 after sending to an electrodeposition painting bath B and finishing the electrodeposition painting. A part of said liquid 3 is sent to a membrane apparatus E provided with the microporous membrane or ultrafiltration membrane and a membrane permeated liquid 4 is sent to an adsorption tower E packed the adsorption medium such as ionexchange resin or active carbon. Then, said liquid 4 is purified by adsorbing and removing the impurities such as heavy metal ion, polyvalent metal ion, polyvalent anion or organic compound in the liquid 4.
