文摘

The difference between the permeance of membranes and that of modules is explained. The effect of membrane permeance on achieved module permeance is investigated. The effects of spacers and retentate flowrates on module permeance are investigated. Ultra-high permeance membranes may not lead to ultra-efficient membrane processes. Fresh research into module and process design is recommended.
