ABSTRACT:
A method for filtering contaminants from a mixture containing an oil-based fluid and a non-oil based fluid is provided. The method includes the steps of providing an oil-based fluid absorbent cloth of man-made fibers, the absorbent cloth having at least a portion thereof that is napped so as to define voids therein; forcing the mixture to flow through the absorbent cloth; trapping, in the absorbent cloth, contaminants from the mixture as the mixture is forced through the absorbent cloth; and absorbing, with the absorbent cloth, the oil-based fluid from the mixture while allowing the non-oil based fluid to flow through the absorbent cloth.
