<p>A back-flushable filtration device is provided. The device includes a monolith (10) of porous material (14) having an inlet end (16) and an outlet end (18). The passageways (22, 26) of the monolith are plugged at the inlet and outlet ends of the monolith, thereby preventing direct passage of feed stock through the passageways from the inlet end to the outlet end. A microporous membrane (28) of mean pore size smaller than the mean pore size of the monolith material covers the surface of the passageways. Methods for making the back-flushable filter as well as methods for using the back-flushable filter also are provided.</p> |
