A cross-flow filtration membrane test unit having a bottom cell body, a top cell body and a pair of laterally spaced O-rings forming a seal therebetween. The bottom cell body is provided with a feed spacer cavity and the top cell body is provided with a permeate carrier cavity. A mechanism for receiving a test sample of membrane enables the membrane performance and characteristics to be tested in a manner which closely simulates actual full-scale operation.

A cross-flow filtration membrane test unit for testing membrane and feed spacer materials usable in a cross-flow filtration device and for simulating the fluid dynamics of such a device comprising: a bottom cell body having a feed inlet to receive fluid to be filtered, a concentrate outlet and a feed spacer cavity having first and second ends, said feed inlet, concentrate outlet and feed spaver cavity formed within said bottom cell body; feed manifold means connecting said feed inlet to said first end of said feed spacer cavity and comprising an elongated opening formed in a portion of said bottom cell body and in communication with said first end of said feed spacer cavity; concentrate manifold means connecting said concentrate outlet to said second end of said feed spacer cavity and comprising an elongated opening formed in a portion of said bottom cell body and in communication with said second end of said feed spacer cavity; a top cell body having a permeate outlet formed therein; means for receiving a test sample of test membrane between said top cell body and said bottom cell body; said feed spacer cavity being shaped to facilitate generally straight line flow of the fluid to be filtered from said first end to said second end of said feed spacer cavity and said feed spacer cavity further being adapted to receive a test sample of test feed spacer; alignment means for aligning said bottom cell body and top cell body relative to one another; seal means comprising a test membrane seal member disposed adjacent one of said bottom and top cell bodies and for engagement with said test membrane to form a seal between said feed spacer cavity and said permeate outlet and further comprising a cell body seal member disposed in sealing emgagement between said top and bottom cell bodies around the entire periphery of said feed spacer cavity, said cell body seal member being spaced outwardly from said membrane seal member about the entire periphery thereof, said alignment means including a plurality of alignment posts connected with one of said top and bottom cell bodies and adapted for insertion into corresponding alignment openings formed in the other of said top and bottom cell bodies, said alignment posts and openings positioned between said membrane seal member and said cell body seal member.
