Dynamic filter system

A dynamic filter assembly comprising:

• a housing having a base, a process fluid inlet, and a permeate outlet;
• a stationary filter unit disposed within the housing and including a plurality of stacked filter elements, each filter element including a pair of opposed major surfaces, a peripheral edge bounding the major surfaces, a permeate passage, and a filter medium disposed on at least one of the major surfaces, each filter medium having an upstream side fluidly coupled to the process fluid inlet and a downstream side fluidly coupled to the permeate passage, wherein one of the major surfaces of one of the filter elements is generally parallel to one of the major surfaces of another of the filter elements, the filter unit further including a plurality of posts coupled to the housing and the filter elements to secure the filter elements to the base of the housing, wherein at least a first post includes a plurality of spacers respectively disposed between the major surfaces of the filter elements to space the filter elements apart from one another, the spacers supporting the filter elements at a location radially inwardly of the peripheral edges of the filter elements, and a bore extending transversely through the major surfaces of the plurality of filter elements and the plurality of spacers, the bore fluidly communicating between the permeate passage of each filter element and the permeate outlet;
• a connector extending transversely of the base and the first post to secure the filter unit against the base;
• and
• a member disposed within the housing facing the filter medium of at least one of the filter elements, the member being arranged to rotate relative to the filter medium to prevent fouling of the filter medium.
