摘要： The present invention relates to a diffusion dialysis apparatus (15) comprising a plurality of anion exchange membranes (1,2) arranged so as to form a stack of successive cell units (16), each cell unit comprising a dialysate compartment (4) for passing a dialysate solution (7) and for collecting acid compounds recovered from a feed, a feed compartment (5) for passing a stream of the feed (6) comprising acid waste with a concentration gradient of the acid between the feed and dialysate solution, and two anion exchange membranes stacked so as to be interleaved with the dialysate compartment and the feed compartment; characterised in that the apparatus comprises an anode (12) and a cathode (13), wherein the cell units are placed between the anode and the cathode,and in that successive anion exchange membranes in the stack of successive cell units are alternately a higher proton transport anion exchange membrane (1) and a lower proton transport anion exchange membrane (2), wherein the higher proton transport AEM (1) has a first H + transport number and the lower proton transport AEM (2) has a second H + transport number, the second H + transport number being smaller than the first H + transport number, such that, in use, acid compounds from the stream of feed (6) are recovered in the dialysate compartment (4) by diffusion dialysis and electrical energy is generated from the directional migration by diffusion dialysis of protons and anions. Use of a diffusion dialysis apparatus according to the invention and a method for recovering acid (or base) compounds from a feed and generating electrical energy is provided as well.
