ABSTRACT:
Disclosed is a filtration process for the removal of undesired substances from dry cleaning fluids. Illustratively, a cylindrically-shaped batt of a long-fiber synthetic washable fabric filter is attached to a spoke-like rigid frame and the fabric-frame assembly is placed into a filter housing having a fluid collecting center rod. Contaminated dry cleaning fluid is introduced to the housing, passed inwardly through the fabric, and a contaminant free permeate is collected by the fluid collecting center rod.
