ABSTRACT:
According to the present invention there is provided a novel type of membrane unit for use in electrodialysis comprising a heat-sealable frame framing and forming an integral entity with an electrodialysis membrane. The frame may be a regular frame, or a two-frame structure framing a single membrane. The invention further relates to electrodialysis devices such as stacks, bags, cells, spiral units and the like based on such membrane units, which are hermetically bonded by heat-sealing to similar units or to polymeric or other members.
