    Abstract: A method and apparatus for filtering suspended solids from a liquid suspension such as sewage, wherein the liquid to be filtered is forced upwardly through a filter media. Upon leaving the filter media, the filtered liquid flows over a weir and into an effluent trough, from where it is directed to an outlet conduit for suitable disposition. The solids entrapped in the filter media during the filtering process are removed therefrom by a cleaning or washing process, which simply involves increasing the rate at which the liquid is passed through the filter media. During washing, the liquid, such as water, is forced through the filter at a rate of flow equal to several times the rate of flow the water moves during filtering, which acts to fluidize the entrapped solids removed from the filter media, enters the effluent trough located above the filter media and because the rate of flow is higher than that during the filtering process, is directed into a compartment spaced away from where the filtered water has been directed. The washwater may then be re-directed through the treatment plant, or to other suitable disposal. The washing operation of the filter can either be pre-set to take place at specified time intervals, or can be initiated upon the establishment of a predetermined back pressure in the filter inlet resulting from clogging of the filter by the solids removed from the water being filtered.

    Abstract: A pipeline filter assembly comprising a base assembly, an outer wall, and a lid assembly. The base plate has a pocket to hold a tool for opening and closing a drain plug. The outer wall has a lower end portion and an upper end portion, wherein the upper end portion comprises a lower collar, and the lower collar comprises threading around an exterior surface thereof. The lid assembly is configured to couple to the lower collar of the outer wall. The lid assembly has an upper collar configured to mate with the lower collar. The upper collar has at least one housing that is coupled to the upper collar, and at least one biasing clip pivotally mounted within the housing for releasable engagement with the lower collar.

    Abstract: A filtering device for removing dirt particles and contaminants from a plastic melt is disclosed. The filtering device includes a housing having a filter chamber, an inlet for feeding plastic melt, an outlet for channeling plastic melt out, and a dirt outlet for discharging dirt particles from the housing. The filtering device also includes a filter element arranged in the filter chamber to retain any dirt particles contained in the stream of melt, and a cleaning unit for cleaning the filter element of dirt particles retained by means of the filter element. The cleaning unit having a cleaning head with a scraper member for detaching dirt particles from the filter element. The scraper member is coupled to a servomechanism to press the scraper member onto the surface of the filter element. The servomechanism has at least one bellows cylinder including a foot section, a head section, a deformable bellows element, and a pressure chamber of variable volume.

    Abstract: A filter assembly for filtering pond or aquarium water includes a container (1,2) with an inlet chamber (15) having an upstream region (36) and a downstream outlet (13) leading to an outlet chamber (22). A filter (16) is positioned in the inlet chamber (15) between the upstream region (36) and the outlet (13). In use, progressive clogging of the filter causes the water pressure in the upstream region (36) to rise until it reaches a predetermined threshold when a normally-closed relief valve (28,29) opens to allow water to pass from the upstream region (36) to the outlet chamber (22) without passing through the filter (16). The valve has a coloured valve stem (28) providing a visual indication that the valve is open and that the filter is blocked and requires cleaning. In one embodiment, the outlet chamber (22) contains a source (19) of ultra-violet radiation to which the flow of water is exposed, regardless of whether the valve (28,29) is in the open or closed condition.
