Document Type and Number:
WIPO Patent Application WO2007024304
Kind Code:
B1
Abstract:
[0040] A wastewater filter assembly comprising a cloth media filter (e.g., a cloth membrane supported by a support cage) having an influent side and an effluent side, an influent valve for controlling flow of influent to the influent side of the filter, a main reservoir (e.g., a tank) in fluid communication with the effluent side of the filter and adapted to hold effluent exiting the filter, and a backwash valve for controlling flow of backwash fluid from the filter. The main reservoir is positioned to hold effluent at a level that is above at least a portion of the filter so that backwashing of the filter can be accomplished using differential head pressure. The assembly can be made of a series of filter cells coupled to each other to form at least part of the filter assembly. Each filter cell is modular and comprises a filter, an influent valve for controlling flow of influent to the influent side of the filter, and a portion of a main reservoir in fluid communication with the effluent side of the filter and adapted to hold effluent exiting the filter. This modular design facilitates expansion of the capacity of the system. Preferably, each filter cell further includes a backwash valve for controlling flow of backwash fluid from the filter.
