A continuous plating bath treatment system directs contaminated plating solution through a specially prepared filter medium and returns the filtered solution to service. The filter medium is a calendered polyester material provided in continuous roll form and is automatically replaced at regular intervals. As a new filter medium segment is drawn into position, a layer of carbon is deposited thereon to provide a chemical filtering element, thus providing chemical and mechanical filtration. Carbon is supplied from a supply hopper by vibrators; adjusting the rate at which vibration occurs conveniently allows adjustment of the volumetric flow of carbon.
