ABSTRACT:
An apparatus for effecting a counterflow liquid treatment of workpieces and particularly an aqueous rinsing of workpieces during an electrochemical treating sequence, such as, for example, an electroplating cycle or the like. The workpieces are subjected to a sequentially-phased treatment with a plurality of solutions while disposed at a treating station, and the individual treating liquids are collected and returned to their respective reservoirs, and the individual reservoirs are counterflowed in a direction opposite to the order of application of liquids to the workpieces.
