Abstract: A regenerative filter that includes a filter housing having inlet and outlet zones; a fluid path provided between the inlet and outlet zones; a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path. The filter elements are disposed in an monolithic array. An inlet port arrangement is disposed at the filter housing leading to the inlet zone and is constructed and arranged to direct the fluid path into the filter housing in a manner so as to maintain a controlled turbulence at the inlet zone. The inlet port arrangement comprises a pair of inlet ports that are arranged in juxtaposition at the inlet zone and each having one end where the fluid flow enters. Embodiments that are considered as falling under the scope of the present invention include 1. Single inlet/two or more outlets; 2. Two or more inlets/single outlet, or 3. Two or more inlets and two or more outlets.

Abstract: A nozzle for a filter cleaning system has a stub portion having an inlet opening and an outlet opening, and a splitter portion positioned downstream of the stub portion. The splitter portion has deflector surfaces arranged to direct the airflow exiting the stub portion outlet in 3 or more different/separate airstreams each of which airstreams are directed inclined axially outwardly from the axial direction of the airflow exiting the stub portion outlet opening. The various parameters of the splitter nozzle portion can be tailored to provide required jet shape and entrainment characteristics. A beneficial feature of the nozzle designs is that jet entrainment and recombination of flows can be specified for different shaped filters.

Abstract: A normal flow filtration system having a housing with one or more filters contained within a bowl and attached to the outlet of the system. Liquid enters the bowl, contacts the surfaces of the one or more filters. Impurities are trapped in the filter and the filtered liquid flows through to the outlet. Parameter(s) such as flow rate, transmembrane pressure drop and/or time are measured and when met, filtration ceases. A backflushing occurs through the filter(s) so as to remove the impurities from the filter. This backwashed material is directed to an outlet of the bowl that is connected to a drain. Additionally a port formed in the side of the housing adjacent an outer surface of the filter(s) can be used to provide a lateral washing of the filter(s). The system is then recirculated in a downstream manner to reestablish equilibrium and filtration is then restarted.

Abstract: A method and apparatus for filtering a slurry utilizing a displacement filtering principle. The filter apparatus desirably includes an inner filter and an outer filter. Both the inner and outer filters are preferably substantially annular in shape and positioned concentrically with respect to each other. A particulate collection volume is at least partially defined between the inner and outer filter. The method includes directing a flow of slurry into the particulate collection volume under sufficient pressure to force fluid within the particulate collection volume through one of the inner and outer filters and any particulate matter blocking a filtering surface of the inner and outer filters.
