[ I claim:] [1.] A waste water filter system for removing solid organic particulate matter and grease from waste water comprising:(a) a collector body (14) having an inflow aperture (10) for receiving the waste water, an outflow aperture (12) and an inner surface (16), said collector body defining a flow path for the waste water extending in a forward flow direction from said inflow aperture, through said collector body, and out said outflow aperture;(b) a removable filter (20);(c) a retainer (54) for releasably securing said removable filter in said collector body;characterized in that said removable filter is expandable as it fills, said removable filter is suitable for removing a portion of the solid organic particulate matter and grease from the waste water, said removable filter positioned in said collector body between said inflow aperture and said outflow aperture, said removable filter having an outer surface (24) and a reservoir (22) for storing the solid organic particulate matter and grease removed from the waste water, said removable filter sized so that, when said reservoir is full, at least a portion of said outer surface of said removable filter is spaced from said inner surface of said collector body and defines a passageway (26) in flow communication with said outflow aperture. [14.] A waste water filter system suitable for removing particulate matter from waste water, said waste water filter system including a waste water supply line (59) in flow communication with a source of waste water containing particulate matter and characterized in that the waste water supply line is in flow communication with:(a) a filtration unit comprising:(i) a collector body (14) having an inflow aperture (10) for receiving the waste water, an outflow aperture (12) and an inner surface (16), said collector body defining a flow path for the waste water extending in a forward flow direction from said inflow aperture, through said collector body, and out said outflow aperture; and(ii) an expandable removable filter (20) suitable for removing particulate matter from the waste water, said removable filter positioned in said collector body between said inflow aperture and said outflow aperture, said removable filter having an outer surface (24) and a reservoir (22) for storing the particulate matter and grease removed from the waste water; and,(b) a grease trap positioned downstream from said filtration unit;whereby the waste water exiting said filtration unit contains a reduced amount of particulate matter and a reduced amount of particulate matter lodges in the grease trap.
