    Abstract: A static screen has a plurality of screening bodies and a plurality of aeration devices downstream of the screening bodies. Each aeration device is associated with a set of one or more of the screening bodies. Each aeration device may be a pulsing aerator. The pulsing aerators do not all release air at the same time. Each screening body works through periods of dead end filtration separated by backwashing events. The backwashing events comprise introducing a slug or pulse of air into the bottom of the screening body. Flow through the static screen continues at all times because the screening bodies are not all backwashed at the same time. The static screen may be used to remove trash from water flowing to an immersed membrane unit. Alternatively, the static screen may be used to provide primary wastewater treatment.

    Abstract: Methods and systems for filtration are disclosed. A feed mixture including at least one liquid component and at least one solid component and a flow of gas may be directed to a filter element and filtrate and gas may be passed through a filter medium from a feed fluid side to a filtrate side. The gas loosens and removes foulants accumulating within and on the upstream surface of the filter medium. The gas and filtrate may be separated from one another after passing through the filter medium.

    Abstract: The disclosure relates to a filter apparatus together with a method for the filtration of liquids, such as, in particular, water, with a housing with an inlet and a filtrate outlet for filtered liquid, with a filter means which is arranged in the flow path of the liquid between the inlet and the filtrate outlet for filtering out particles from the liquid, and with a dirt discharge via which filtered-out particles can be discharged from the housing, the filtrate outlet being assigned an outlet valve and the dirt discharge being assigned a discharge valve. According to the disclosure, the outlet valve and the discharge valve are coupled in such a way that the discharge valve opens the dirt discharge only when the outlet valve has at least partially shut off the filtrate outlet, in order thereby to generate a cleaning pulse.

    Abstract: An apparatus for the separation of a solid/liquid suspension by filtration includes a tank filled with a suspension to be treated. At least one cavitied plate is located in the tank and has at least one internal cavity. The plate is immersed in the suspension to be treated. The plate is inclined with respect to the vertical and only a lower inclined face of the plate is covered with a filter medium, the upper face being solid. The compartment of the cavitied plate communicates with a conduit which collects filtered suspension. Gas flushing pipes are positioned below the plate for emitting gas bubbles that pass across the filter medium and remove material clinging thereto.

    Abstract: A filter (102) for filtering fluid from a machine (104) includes a filter housing (106, 250) having a first inlet (114) receiving a first fluid from the machine, a first outlet (116) returning the first fluid to the machine, a second inlet (118) selectively receiving a second fluid from a source (120) of cleaning fluid, and a second outlet (122) for exhausting the second fluid and for exhausting the first fluid from the dirty side of the main filter element (124) in the housing backwashed by the second fluid. The filter housing has a first flow path (126) therethrough from the first inlet then through the filter element in one direction then to the first outlet, and has a second flow path from the second inlet then through the filter element in the opposite direction then to the second outlet, the first and second flow paths having common but opposite direction portions through the filter element. A second filter element (156) is provided in the second flow path.

    Abstract: An air/water distributor underdrain assembly for providing a uniform distribution and metering of backwash air and/or water through a filter bed. The distributor assembly includes a distributor member which defines a distributor chamber for receipt of backwash air and/or water thereinto. A plurality of first and second spaced apart openings extend through the distributor member. A shroud extends downwardly into the distributor chamber from each of the first openings in fluid communication with an intermediate portion of the distributor chamber for directing backwash water therethrough. Backwash air collected in a gas compartment formed in an upper portion of the distributor chamber is directed through the second openings.
