Abstract

Device comprises a stack of membranes permeable to the elements, with frames, impermeable to the fluids, interposed between the membranes. An exchange device for two fluids A and B, consists of a first interposed piece, a first exchange membrane, a second interposed piece, a second membrane and a third interposed piece; two of the membranes and an interposed piece constitute an exchange chamber. The interposed piece consists of a perforated structure of the grid type supported by a frame, which is thicker than the grid. The frames are made by the hot-pressing of a plastic material on the periphery of the grid structure. The stack of very thin exchange chambers is readily made up by means of the monoblock structure of the interposed pieces. The device can be used for ultrafiltration, reverse osmosis, dialysis and electro-dialysis; in the latter case the membranes are alternately anionic and cationic.
