Abstract: This invention relates to a micro-effluent process for rinsing water and equipment for the same in industrial processing, especially in electroplating processing. The process of the present invention is characterized in that periodically tank-turning over, that is, at definite time intervals, the rinsing solution is transferred from the first rinse tank to a high level storage tank or to a working-tank (plating-tank), from the second rinse tank to the first rinse tank, and so on and so forth, at last from the last rinse tank to its preceding tank, and the empty last rinse tank is filled up by clean water with a flow rate of less than 400 l/h, or filled up with clean water periodically at a definite time interval same as that for tank-turning over.
