    Abstract: A filter assembly (110) includes a filter vessel (112) having an inlet (114), an outlet (116), and defining a filter chamber (118) therebetween. A basket assembly (124) is removably supported within said filter chamber (118) and has a diameter less than the diameter of the filter chamber (118) so as to define an annular flow path (128) about the basket assembly (124). The basket assembly (124) includes an outer, permeable member (130) and an inner, permeable member (132) having a diameter which is less than the diameter of the outer, permeable member (130) so as to define an annular space (136) therebetween and an inner flow path (C). The basket assembly (124) supports a bag-type filter (142) over both the inner and outer permeable members (130, 132) bounding the annular space (136) therebetween. The bag-type filter (142) includes a first portion (144) having a first, larger diameter and a second portion (146) having a second, reduced diameter. A transition portion (148) is disposed between the first and second portions (144, 146) of the bag-type filter (142).

    Abstract: A sealing ring (140) adapted for use in connection with a filter bag assembly (138) of filtering apparatus (110) is disclosed. More particularly, the sealing ring (140) has an annular body having an annular support wall (164) which is sized and shaped so as to be supported on a supporting structure (130) of the filtering apparatus (110). An outer annular wall (162) projects substantially upwardly from the support wall (164), while an inner annular wall (160) projects substantially upwardly from the support wall (164) and is located radially inwardly from the outer wall (162). An annular groove (158) is formed between the inner and outer walls (160, 162) and is delimited by the support wall (164). The outer wall (162) is sized and shaped so as to engage an adjacent sealing surface (132) of the filtering apparatus (110) in a substantially fluid-tight manner, while the support wall (164) is sized and shaped so as to engage the supporting structure (130) in a substantially fluid-tight manner.

    Abstract: A method of wet-grinding a surface, particularly a floor comprised of stone or stone-like material, wherein liquid is delivered to the area of contact between a grinding tool and the grinding surface, wherein liquid-bound particulate solids are withdrawn from the grinding area by suction and filtered to extract the particulate solids from the liquid, and wherein the liquid filtrate is returned to the tool grinding area. The grinding tool (2) is encircled by a skirt (3) whose rim seals against the surface (30). The flow of liquid and solids is led to one or to a few of a plurality of filter bags (11) and the liquid/solids flow is switched to a fresh bag (11) or to a fresh group of bags (11) when a previous bag or previous group of bags has been filled, wherein the previous bag or group of bags is isolated from the flow (5) and left for the liquid to drain gravitationally therefrom as the fresh bags are being filled. The bags are removed and sealed when liquid no longer runs from the bags.

    Abstract: The invention relates to the treatment of liquid waste such as sewage. The invention provides a method of screening of liquid waste to remove solid material therefrom, comprising passing the liquid waste in a downward stream through a suspended sack filter, and agitating the sack filter and the liquid stream by discharging a stream of bubbles upwardly through the liquid from below the sack filter. The invention also provides an inlet screen, comprising an upright hollow column (1), having an opening at the top across which a sack filter (6) is positioned, the sack filter extending downwardly into the column, and an air diffuser (8) at the lower end of the column, and an outlet (5, 23, 34) from the column, whereby in use liquid waste flows into the top of the column, through the sack filter to the outlet, the sack filter and liquid waste being agitated by discharge of air from the air diffuser.

    Abstract: A press assembly (10) for squeezing liquid from layers of liquid containing materials. The press assembly utilizes a plurality of open top filter bag assemblies (102), each filter bag assembly being disposed between adjacent press racks (86), the press racks being mounted on parallel horizontally extending rods (52) for sliding movement thereon, the rods in turn being supported between spaced apart platens (42, 54). When the press racks are moved towards one another to squeeze juice from the liquid containing material which is disposed within the filter bag assemblies, the juice will flow into a collector (176) mounted below the press racks. The press assembly is capable of inverting the press racks and filter bag assemblies after the press racks have been moved away from each other, the residue from within the filter bags being discharged onto a conveyer (220) mounted below the collector which has been moved from its operative position below the press racks to an inoperative position to the sides of the press racks.

    Abstract: Industrial filtration apparatus for the separation of solids entrained in a fluid stream comprises: a flexible perforate filtering sleeve closed at one end such that fluid can pass through perforations in the sleeve but entrained solids of a predetermined size are retained within the closed end of the sleeve. The apparatus has a structure for holding the sleeve about a discharge pipe for the fluid at a point between the closed and open ends of the sleeve, and for restraining movement of the sleeve away from the pipe; the apparatus is adapted such that in response to a predetermined fluid (e.g. hydraulic) pressure within the sleeve between its closed end and the discharge pipe, the closed end is allowed to be displaced away from the discharge pipe, thereby drawing a portion of the sleeve nearer its open end into a position forward of the pipe to expose said portion to the fluid stream.
