Distribution plate for crossflow cassette-type filtration devices

摘要

A cross-flow cassette filter has rectangular distributor plates holding a filter module. The filter comprises essentially of three parts consisting of upper, center and lower plates which when combined present front, rear, side outer surfaces and edges. The center plate has an inlet and run-off tubes parallel to the edges and corner walls, running to the front and rear faces via the side faces. Preferred Features: The filter is a mono- or bi-directional unit for a cross-flow ultra-filter or micro-filter. The unit facilitates the link-up of a number of filter cassettes. The three-piece structure sustains uniform pressure at all apertures, maintaining uniform fluid flow over the entire membrane surface.
