PLATE DIALYZER WITH ASYMMETRICALLY TENSIONED MEMBRANE

摘要

A diffusion device has a plurality of stacked plates and overlying membranes with the plates defining a plurality of rows of spaced projections of uniform height to form flow channels. The membranes overlying the plates are selectively tensioned in one direction with respect to other directions over the projections. The center-to-center spacing of the projections in the one direction is greater than in a direction transverse thereto.
