ABSTRACT:
A system and method are provided for the on-line filtration of potassium permanganate desmearing solution. The solution, with manganese dioxide precipitate, is continuously pumped from a desmearing tank so the precipitate can be removed. The system has piping resistant to any chemical corrosion that either the solution or the precipitate may cause. An air-driven diaphragm pump is used to pump the solution-precipitate mixture through the system. A multi-tube filter unit removes the precipitate from the mixture. The filtered, precipitate-free, solution is then returned to the desmearing tank.
