Abrégé

A high velocity cross flow dynamic membrane filtration system includes a disc membrane assembly having a frame and at least three support shafts in an orthogonally positioned relationship, each support shaft defining a longitudinal axis about which is positioned a plurality of axially spaced membrane discs, each shaft further coupled to the frame. A permeate tube is coupled to each support shaft and is in fluid communication with the membrane discs associated with that support shaft. A vessel defines a treatment chamber and is configured to removably support the disc membrane assembly within the treatment chamber. The vessel further includes a wall. The permeate tubes are configured to extend through a portion of the vessel wall when the disc membrane assembly is positioned within the treatment chamber. The permeate tubes are further configured for rotation by a drive system.

A high velocity cross flow dynamic membrane filtration system disc membrane assembly includes a frame having first and second end members and a plurality of rails extending between the first and second end members. At least two parallel support shafts are coupled to the frame, each support shaft defining a longitudinal axis about which is positioned a plurality of axially spaced membrane discs. The plurality of membrane discs associated with one of the at least two parallel support shafts is interspersed between the plurality of membrane discs associated with another of the at least two parallel support shafts. Each rail of the plurality of rails is configured to be received by a mounting rail within a vessel defining a treatment chamber. A permeate tube is coupled to each support shaft and in fluid communication with the membrane discs associated with that support shaft.

Abrégé

A method of operating a high velocity cross flow dynamic membrane filtration includes feeding a fluid stream into a pressure vessel, in which the vessel defines a treatment chamber containing a disc membrane assembly having a first support shaft and a second support shaft, each support shaft defining a longitudinal axis about which is positioned a plurality of axially spaced membrane discs. The method further includes distributing the fluid stream over at least a portion of the disc membrane assembly. The method also includes discharging a first portion of the fluid stream from the vessel and discharging a second portion of the fluid stream from the vessel. The method additionally includes rotating the first support shaft and the second support shaft in a first direction. The rotating includes modulating a rotation rate in response to the flow rate of the second portion of the fluid stream.
