ABSTRACT:
A pretreatment apparatus for performing pretreatment before a painting process includes a treatment tank to be filled with a treatment liquid for degreasing and chemical conversion. A circuit section forms a circulation path for circulating the treatment liquid from the treatment tank to the treatment tank. A purifying section removes dust, chemical sludge and oil from the treatment liquid circulated to the treatment tank through the circulation path.
