A separation membrane module may decrease a bending load applied to a support member supporting ends of tubular separation membranes and omission of a seal member between the outer circumferential surface of the support member and the inner circumferential surface of a housing. The separation membrane module may include a tubular housing, tubular separation membranes arranged in a longitudinal direction of the housing, end tubes connected to lower ends of the tubular separation membranes, a support box supporting the end tubes, and a backpressure chamber below the support box. The tubular separation membranes may be in communication with a support box collection chamber. A nozzle disposed on the support box may extract permeated fluid. A chamber and the backpressure chamber are in communication via a gap between the support box outer circumferential surface and the inner circumferential surface. The chamber and backpressure chamber have substantially the same pressure.

A crossflow filter includes a rigid cylindrical inner wall and a rigid cylindrical outer wall with an inelastic filter membrane positioned therebetween defining a retentate channel inside the filter membrane and a permeate channel outside the filter membrane. Further, the filter includes transition channels shaped and connected to the inner and outer walls to deliver a flow of fluid from an inlet port to the retentate channel and to capture flow flowing longitudinally along the cylindrical inner and outer walls from both the retentate and permeate channels to respective outlet ports.
