Rotation of drum removes process solution.
Drain boards provide areas to capture drag-out without
interfering with the plating tank.

j) Static tanks - use more than one rinse tank, making
the first one a "static" tank. That is, do not use a continuous
overflow tank that is continuously diluted with fresh incoming
water. Most of the drag-out from the plated piece can be rinsed
into the static tank, leaving the next rinse tanks cleaner
longer. The static tank can be refilled as needed, and when
concentrated may be recycled or disposed of as waste.
k) Multiple countercurrent rinse systems - employ
several tanks that all use the same freshwater feed. The plated
parts are successively rinsed in tanks with increasingly clean
