Abstract
A membrane module in which non-porous membranes are bonded to spacer elements, which elements are in turn bonded to each other to create a membrane support zone as a result of contact with the surface of the membrane opposite the surface to which the membrane is bonded. The membrane is restrained from peeling from the membrane bond by the support zone under opposing pressure as may be caused by fluid flowing past the membrane. The preferred use of such a membrane module is for continuous electrodeionization processes.
