ABSTRACT:
A cross filter device which includes a tube of helically wound wedge wire. Contaminated influent enters at one end. As it flows through the tube, it becomes more concentrated with contaminants, while clarified liquid permeates through the tube wall. Parallel or series combinations of two or more elements enhances their capacity. The device is particularly suited for handling large volumes of grossly contaminated liquids, such as machining and grinding coolants.
