Abstract

A filtration system for cleaning the fluid in a wash tank. The filtration system includes a process tank from which fluid is pumped to a filter element located in the wash tank. The filter element is formed of hollow porous tubes. The fluid is pumped from the process tank through the hollow porous tubes and back to the process tank. The fluid in the hollow porous tubes is at a greater pressure than that of the fluid in the wash tank in which it is submerged, such that fluid, but not particulate matter, with flow through the pores in the tubes to the wash tank. Cleaned fluid is thereby provided to the wash tank and fluid with a higher concentration of contaminants is returned to the process tank.
