Abstract
An apparatus for removing contaminates from caustic washing solution used in jet washers and the like such that the washing solution can be used for extended periods without replacement or disposal. The apparatus includes a filtration tank adapted to be connected to a tank of a jet washer for receiving caustic washing solution. The filteration tank houses a filter bag, and a pump is disposed in the filtration tank. The pump forces caustic washing solution through the filtration bag, to provide for removal of oil and grease from the washing solution, and also pumps washing solution into the tank of the jet washer to thereby cause flow of washing solution between the tank of the jet washer and the filtration tank.
