ABSTRACT:
A stacked permeable membrane envelope assembly comprises two clamping plates with spaced, permeable membrane envelope assemblies clamped between them on frames. Each membrane envelope comprises two membrane covered, perforated plates clamped together to provide inner permeate chambers and outer feed fluid passages. Fluid distributing and permeable membrane sealing collars are provided comprising two annular plates with a radially scalloped, stiff-spring-like, channel separator ring located between them. The annular plates seal the membranes against the dished plates around feed fluid passages through the envelope assemblies while the radial scallops form passages for fluid to flow between adjacent membrane envelopes.
