Apparatus for mass transfer having a package of membranes

摘要

An apparatus for mass transfer, in particular a plate dialyser, has a multiplicity of membrane layers, each of which are provided with a spacer layer which is formed by an embossed and cured polymer mass. The membranes are preferably brought into contact with each other before the mass has cured, so that a completely sealed membrane package results. The membranes themselves have, in addition to a surrounding spacer edge and individual sealing arrangements in the region of the through-holes, a multiplicity of spacer points which are distributed about the remaining membrane surface. <IMAGE>
