ABSTRACT:
Apparatus for mass transfer between fluids, comprises two permeable membranes with a porous membrane support sandwiched therebetween, all pleated together with an accordian pleat to form a pleat package, and sealed in a casing to define three flow channels from one end of the casing to the other, to form a filter having a large filter area in a minimum amount of space for use as a dialyzer or as an ultrafilter in the treatment of blood. By selection of different membrane materials, the apparatus may also be used for oxygenation of blood, and three different fluids, including both gases and liquids, may be treated.
