A disposable, crossflow membrane stack suitable for use in an ion exchange unit, the stack comprising alternate dilution compartments and concentration compartments, each compartment being defined by a flat cation-permeable membrane (2) and a flat anion-permeable membrane (1) and at least two edges along which the cation-permeable and an anion-permeable membranes are permanently secured together wherein the cation-permeable membranes and/or the anion-permeable membranes have a textured surface profile which keep said membranes apart and/or from touching each other and wherein the edges secured together define the direction in which liquid may flow through the compartments. Also claimed are ion exchange units comprising the stack, optionally comprising a quick-release securement means to allow facile attachment and release of modular units comprising the stacks.
