Abstract: A removable drain filter apparatus (20) with an housing (22) connectable with upstream and downstream drain pipes (40, 46) has a filtering chamber wider than the drain pipes and divided into an upstream portion (78) and a downstream portion (82) by a generally planer filter element (50). A hatch cover (32) carries a downwardly extending central core (76) with an O-ring seal (84), a filter securement member (86) for pressing the filter element (50) against an underlying support ledge (29) and a drain hole plug (88). The location of the O-ring (84) relative to the filter element (50) and the plug (88) being tapered enables the filter housing (22) to be drained of any water during removal of the hatch cover and before the watertight seal is broken to eliminate leakage of drain water out of the housing (22) when the hatch (31) is completely opened. The filter (50) bends out of the way of a plumber's auger (96).

The flow is primarily returned thereto by means of a contraction in the feed channel at the mouth of the return channel. Preferably, a solid separator is disposed in the return channel. At least one baffle element is arranged in the feed channel in order to create a turbulent flow. The tangential flow along the filter membrane is used to clean said membrane.

Abstract: A fluid filter is provided with a case body defining therein a holder and having pressing portions formed on the internal wall surface of the case body. The pressing portions can compress a filter medium housed in the holder. The pressing portions are pressed against the filter medium housed in the holder to compress it and form a compressed region at a desired position of the filter medium, where the rate of capturing extraneous substances is increased. Thus, even if various sizes of the extraneous substances are contained in a fluid introduced through the inlet into the holder, the filter medium can capture the extraneous substances in its entirety. The degree of compression of the compressed region in the filter medium changes depending on the height of each pressing portion.

Abstract: A plurality of elongated hollow, circular, foraminous substantially vertical tubes contiguously stacked transversely to the direction flowing liquid such as waste water containing foreign matter, i.e., settable solids and free oil, in a coalescer-separator apparatus provide a filter body providing for significant surface area contact by the liquid on both inside and outside surfaces of the tubes to entrap the foreign matter but defining substantially vertical passages permitting the entrapped foreign matter to be gravity separated with the lighter matter coalescing and floating upwardly and the heavier matter settling downwardly so that substantially clarified effluent flows from the apparatus. The stacked tube filter body is contained within an insulated closed container of a sufficient capacity, and the arrays of holes in the tube walls are coordinated with respect to the intended volumetric capacity of the apparatus, so that turbulence in the liquid flowing through the filter body is minimized.
