摘要： An improved vertical filtration unit which includes an airlift and a washbox designed for more efficient washing of dirt particles from the filtration material. The washbox consists of a filter media shield, and a washbox skirt for washing of the filtration material. A throttling valve on the wash water discharge line regulates the overall cleaning rate of the unit. The filtered liquid is discharged via a riser pipe which feeds into a filtered liquid box before exiting the filtration unit.

摘要： Method of filtering liquid using a vertical filter, which includes media, an airlift, a washbox, a reject box, a filtrate chamber, and an effluent box. The method of filtration and media cleaning is automatic. The filtered liquid is collected by multi-cartridge screens before entering a filtrate chamber. The filtrate flows from the filtrate chamber into an effluent weir box. The liquid level in the filter is controlled by an effluent weir in the effluent weir box. The reject line is below the water level in the filter, which provides the driving force for the reject flow. The reject rate is controlled by liquid level in the filter tank and a throttling valve on the reject discharge line. The washbox includes a filtration material shield, a filtration material/dirtied liquid separation zone, and a washbox skirt with a washbox isolator, which prevents the dirt in the washbox form entering the influent zone.

摘要： Methods and apparatus for treating water and wastewater include the step of flowing a suspended solids stream generally upward through a sludge blanket region of a cloth disk filter vessel, thus forming a partially treated effluent composition and a solids-enriched sludge blanket. The partially treated effluent composition is allowed to flow generally upward to a cloth filter zone in the vessel after contacting the sludge blanket. The methods include flowing the suspended solids stream through one or more distribution headers positioned in the sludge blanket. An option is to provide a sludge concentration zone in the sludge blanket region, allowing sludge to flow into the sludge concentration zone to form concentrated sludge. Other methods and apparatus include backwash assemblies that backwash substantially the entire filter cassette surfaces, with or without use of a sludge blanket zone. Either the backwash assemblies or filter cassettes move in the latter methods and apparatus.
