Abstract: A cleaning system for cleaning a lamella plate settler includes at least one mechanical cleaning device; a suspension device adapted to suspend the mechanical cleaning device; wherein the suspension device includes a displacement device for lowering and raising the at least one mechanical cleaning device for mechanical cleaning of a lamella plate positioned below the cleaning system. By providing a frame supporting the at least one cleaning device; wheels attached to the frame and adapted to move on rails, the wheels including driving wheels and non-driving wheel, and a sensor, preferably an inductive sensor, adapted to sense the rotational position of the driving wheels, the lamella plate settler can be automatically be cleaned without emptying the basin of water, thus allowing cleaning during operation. A lamella plate settler and a method of cleaning a lamella plate are also provided.

Abstract: A method and a plant for the treatment of water or wastewater having impurities by filtration of the water through two granular media filter stages of the moving bed type operated in series. The method includes the steps of feeding the water/wastewater as a first influent to first stage granular media filters; filtration of the first influent in the first stage granular media filters to produce a first effluent; feeding the first effluent as a second influent to second stage granular media filters; and filtration of the second influent in the second stage granular media filters to produce a second effluent. The second stage granular media filters are operated with intermittent washing of the granular filter media.

Abstract: A filter element for use in a filter disc, wherein a plurality of filter elements are arranged on a rotor shaft in a manner allowing liquid communication between the inside of the filter elements and the inside of the rotor shaft. The filter element has at least one passage in an edge structure for liquid communication between the inside of adjacent filter elements when the filter elements are assembled forming a filter disc. The passage has different passage area along the edge structure.

Abstract: The present invention relates to a fabric disc filter having a structure for preventing damage to a filter panel. In this regard, an object of the present invention is to provide a fabric disc filter having a structure for preventing damage to filter panel, being capable of preventing the filter panel attached to the filter panel from being torn or being disconnected from the filter frame in the washing process of suctioning and removing foreign matter. To accomplish this object, the present invention provides a fabric disc filter having a structure for preventing damage to filter panel, the fabric disc filter including: a rotary drum; and a plurality of filter segments arranged on an outer circumferential surface of the rotary drum, wherein each of the filter segments includes: a segment frame that is partially open so as to enable inlet of a fluid therethrough, and being configured to discharge the inlet fluid to the rotary drum; a filter frame assembled to the segment frame so as to be positioned on the fluid inlet side of the segment frame; a filter panel provided in the filter frame so as to filter foreign matter in the fluid flowing therethrough; and a rod-shaped stopper provided in the filter panel so as to distribute a load applied to the filter panel in a washing process of the filter panel and couple the filter panel to the filter frame or the segment frame.

Abstract: A lamella settler (1) comprises a basin (10) with an inlet for liquid to be cleaned and a sludge outlet and with a plurality of outlet openings (12) for cleaned liquid. Each of a plurality of outlet flumes (16)connects to one of the plurality of outlet openings (12). A plurality of lamella plates are (18) attached to adjacent flumes (16). By providing a plurality of transverse beams (14) above the basin (10), wherein the outlet flumes (16) are supported by the beams (14), an improved lamella settler is achieved which is easier to manufacture and assemble and which has improved characteristics.

Abstract: In a filter element for use in a filter disc, a plurality of filter elements are arranged on a rotor shaft in a manner allowing liquid communication between the inside of the filter elements and the inside of the rotor shaft. The filter element has at least one passage in an edge structure for liquid communication between the inside of adjacent filter elements when the filter elements are assembled forming a filter disc. The passage has an elevated retention edge extending along at least one edge of the passage. Transportation of particles between filter elements in a disc filter is thereby minimized.
