Abstract: A filter cloth of long pile fiber bundles is used as a tertiary filter in a wastewater processing method. The filter may be backwashed by a rotating suction head which does not touch the filter cloth. A combination of countercurrent and horizontal flow dislodges entrained solids from the filter cloth. Mounting of the filter media as modular components permits increased capacity within a single tank while avoiding down time in changeover of filter media.

Abstract: The present invention is a screening/washing/dewatering system which utilizes a solids handling pump to vacuum solids captured from a contaminated fluid stream from the system's screening mechanism and to convey them, in a concentrated form and through a closed conduit, to the washing/dewatering mechanism. The use of a solids handling pump enables a screening, washing and dewatering system to contain the captured solids in a completely closed system from their point of capture, through a conveyance system of unlimited length and configuration, to the point that the washed, dewatered screenings are finally discharged. Secondarily, the present invention offers the advantages of being able to capture as small of a solids particle size as is desirable and of providing effective washing and dewatering of the captured particles while minimizing the number of moving parts and maximizing the overall system reliability.

Abstract: The aim of the invention is to improve the backwashing action of a backwashable filter for liquids comprising the following: a filter body which is located in a housing and which separates an incoming flow chamber from an outgoing flow chamber and a backwashing channel which lies adjacent to the filter body, is situated in the outgoing flow chamber and has a backwashing opening that faces towards the filter body, said backwashing channel also communicating with a source of a cleaning medium and said cleaning medium being subjected to pressure in the backwashing channel, and the filter body and the backwashing channel being moveable in relation to each other. To this end, the filter body has links on a side facing towards the backwashing channel which are set apart from each other in the direction of motion. Adjacent links form a separately backwashable segment respectively and when a segment is backwashed, the corresponding links lie sealingly against the backwashing channel with sealing surfaces and expose the backwashing opening. Each sealing surface extends further than the backwashing opening in the direction of motion, so that each link can tightly seal the backwashing opening with its sealing surface.

Abstract translation: 本发明的目的是改进用于液体的反冲洗过滤器的反冲洗动作，其包括以下内容：过滤器本体，其位于壳体中并且将进入的流动室与来自流出室和反冲洗通道相隔离 过滤器主体位于流出的流动室中并具有朝向过滤器本体的反冲洗开口，所述回洗通道还与清洁介质的源连通，并且所述清洁介质在反冲洗通道中受到压力，并且 过滤器主体和反冲洗通道可相对于彼此移动。 为此，过滤器主体在朝向反冲洗通道的一侧上具有在运动方向上彼此分离的连接。 相邻的链节分别形成分开的反冲洗段，当段被反冲洗时，相应的链节密封地抵靠具有密封表面的反冲洗通道，并暴露回洗开口。 每个密封表面在反冲洗开口的运动方向上延伸得更远，使得每个连接件可以将反冲洗开口与其密封表面紧密地密封。

Abstract: A filter cleaning apparatus includes a suction generating assembly having a suction generating nozzle, such as an eductor nozzle. The suction generating nozzle has a nozzle inlet, a nozzle outlet, and a suction port in fluid communication with the filter material. The suction generating assembly also includes a suction member positioned in fluid communication with the suction port and positioned adjacent the influent surface of the filter material. A pump is positioned upstream of the nozzle inlet and in fluid communication, on a suction side, with the filter tank or other liquid source. The pump may be operated to deliver operating fluid from the filter tank so as to pass the operating fluid through the suction generating nozzle in a direction from the nozzle inlet to the nozzle outlet. As a result, liquid in the filter tank is drawn through the filter material in a reverse direction and into the suction member. The liquid stream that results acts to remove filtered solids and biogrowth from the filter material. The liquid stream, filtered solids and biogrowth, are discharged along with the operating fluid through the nozzle outlet.
