摘要： Water or wastewater filtration systems and processes have a filter tank having a floor and sidewall defining a filtration zone, an influent conduit, and an effluent conduit. One or more filtration members in the tank having filter media, and one or more cleaning members adjacent at least some portions of the filter media. Generating an effluent stream by generating a pressure differential across submerged portions of the filtration media, causing water in the influent to flow from outside to inside the submerged portions of the filter media. A prime mover rotates the filtration members. A blower and chamber for creating a reduced pressure condition in each of the cleaning members when they are non-submerged, the chamber receiving wet solids removed from non-submerged, wet solids-laden portions of the filter media by the non-submerged cleaning members subsequent to submerged, fouled portions of the filter media being rotated out of the filtration zone.
