A filter device has a filter housing (1) having a fluid inlet (11) for unfiltered matter, a fluid outlet (19) for filtered matter and at least one filter element (7, 9) of one or more parts accommodated in the filter housing (1). The filter element can be cleaned using at least one backwash element (21) in counter current to the direction of filtration. The backwash element can be moved by a fluid-conveying drive shaft (20) of a rotary drive at the inside (17) of the relevant filter element (7, 9). At the end adjacent to this inside (17), a gap-shaped passage opening is parallel to the axis of rotation (16) of the drive shaft (20) and opens into a flow chamber connected to the drive shaft (20) in a fluid-conveying manner. The distance between the backwash element (21) and the adjacent assignable filter element (7, 9) can be predetermined by an adjustment device (27; 47).

A filter for use in filtering a fluid slurry that includes particles of varying size, such as pool water including debris, is provided. The filter is in electrical communication with a sensor and includes a housing having an inlet to receive the fluid slurry, an outlet, and an internal chamber. An actuator can be coupled to the filter media to move at least a portion of the filter media to vary a dimension of the pores. The filter also includes a controller connected to the actuator that is capable of receiving a signal from the sensor and controls the actuator to change the dimension of the pores based on the signal.

A filter device, in particular for lubricating oil filtration, includes at least two filter inserts (27), in each of which a filter material (43) is accommodated. The filter inserts are provided with fluid passage points (37, 39) and can be stacked on top of one another with the formation of a stack. A back-flushing device (55,57) is movably arranged along the inner side of the filter inserts (27). The individual filter inserts (27) are designed as identical parts at least with respect to their housings.

A filter having a hollow body extending longitudinally between a first end and a second end and comprising a plurality of holes formed through said body, and a first compliant section formed in said body, said compliant section comprising a plurality of slits which extend through said body and in a circumferential direction around said filter. A nozzle/filter assembly is also described as well as a method for making the same.

A filtering apparatus (100) having a filtering mode and a self-cleaning mode, the apparatus provided for filtering an upstream flowing fluid with filtering elements (20) in the form of a plurality of stackable discs during filtering mode utilizing a first flow direction, apparatus (100) also configured to self-clean the filtering elements (20) the apparatus (100) including an internal fluid diverter (110,210, 310) that is internal to the filter housing. The position of the internal fluid diverter determines the direction of fluid flow through the filter housing and the filter phase. The position of the internal fluid diverter is controlled with a controller disposed external to the filter housing that may be manipulated either manually or by automated means.

A filter device, comprising a filter housing (1) having a fluid inlet (8) for unfiltered matter and having a fluid outlet (9) for filtrate and having at least one one-piece or multi-part filter insert (05, 17) held in the filter housing (1), which filter insert (15, 17) can be cleaned using a backwash device (25) having at least one backwash element (31) in counter flow to the direction of filtration, which backwash element can be moved along the inside of the relevant filter insert (15, 17) by means of a fluid-conveying drive shaft (29) of a rotary drive (69, 71), wherein the individual backwash element (31) has, at the end adjacent to this inside, at least one gap-shaped passage opening, which extends in parallel to the axis of rotation of the drive shaft (29) and which opens into a flow chamber connected to the drive shaft (29) in a fluid-conveying manner, is characterized in that at least one further backwash device (27) having at least one further backwash element (31) is present, in that the fluid-conveying drive shaft (29) is divided into chambers (73, 75) separated from each other, and in that in each case one backwash element (31) of one backwash device (25) is connected to one of the chambers (73, 75) and the other backwash element (31) of the other backwash device (27) is connected to another chamber (73, 75).

An active strainer contains a housing with a cover, a base and side surfaces made in the form of filtering elements, pipes with channels fixed at one end at the central vertical axis of the strainer and configured to supply purified fluid from the central part of the strainer to the filtering elements from the other end of the pipe through channels, wherein the strainer housing is made of two parts, an upper and a lower one, each part is equipped with at least one filtering element, the turbine is installed between the upper and lower part and configured to rotate during the fluid flow passage through it, the turbine shaft is connected with the pipes, which are capable of sampling the purified fluid from the strainer housing during rotation of the turbine.

A flue gas cleaning solution purification system includes: a scrubber for removing contaminants from flue gas by using a cleaning solution; a cleaning solution purification unit for purifying the contaminated cleaning solution discharged from the scrubber; a cleaning solution resupply unit for resupplying the cleaning solution having been purified by the cleaning solution purification unit to the scrubber; and a sludge treatment unit for treating and storing sludge discharged from the cleaning solution purification unit, wherein the cleaning solution purification unit includes: a circulation buffer tank for temporarily storing the discharged contaminated cleaning solution; a coagulant supply apparatus for supplying a coagulant which coagulates contaminants of the contaminated cleaning solution discharged from the scrubber; a settling apparatus for primarily purifying the contaminated cleaning solution discharged from the scrubber by enabling settling of the contaminants; and a filtering apparatus for secondarily purifying the cleaning solution by filtering the contaminated cleaning solution to remove the contaminants.
