    • A membrane stack unit for performing a multichamber treatment of plural component fluids, composed of a plurality of sealing frames, membranes interposed between the frames, and two end plates with milegrated electrodes disposed at respective opposite ends of the unit with the frames and membranes interposed therebetween. Each frame has four side edges enclosing a region constituting a treatment chamber, with one pair of opposed side edges being provided with a set of through bores for conducting fluid, a set of second bores, and inlet and discharge channels each communicating with a respective second bore and with the chamber, and the second pair of opposed side edges being provided with through bores for conducting fluid. Each membrane is provided with openings aligned with all of the bores. The sealing frames are oriented relative to one another such that at least some of the through bores in one frame are aligned with respective ones of the second bores of another frame. Each end plate is provided with a plurality of bores forming flow paths with selected ones of the bores in the sealing frames, and a plurality of fluid flow channels communicating with the bores in that end plate, and a plurality of bores and two collecting channels for the entrance and discharge of the electrode rinse solution.

    • A sealing frame for alternately arranged anion and cation exchanger membranes of a membrane stack for electrodialysis. The frame edges surround a chamber provided with a net-like spacer placed or inserted therein, and have oppositely located continuous supply and connection bores passing therethrough for the solution to be treated and for the solution enriched with or depleted of separated dissolved electrolyte or electrically non-charged dissolved materials. These bores alternately communicate by means of supply or discharge troughs or channels with the interior of the chamber. The supply and discharge troughs or channels diverge to such an extent in a direction toward the chamber interior that the flow media are distributed in essence over the complete width of the flow path between the cooperating supply and discharge troughs or channels. Furthermore, the net-like spacers extend as far as into the diverging regions of the supply and discharge troughs or channels.
    • 用于电渗析的膜堆叠的交替排列的阴离子和阳离子交换膜的密封框架。 框架边缘围绕设置有放置或插入其中的网状间隔件的室,并且具有相对定位的连续供应和连接孔穿过其中以进行待处理的溶液,并且对于富含或耗尽分离的溶解电解质或电非空气的溶液 - 溶解的材料。 这些孔通过供应或排放槽或通道与室的内部交替地连通。 供应和排放槽或通道在朝向室内部的方向上发散到这样的程度,流动介质本质上分布在配合的供应和排出槽或通道之间的流动路径的整个宽度上。 此外,网状间隔物延伸到供应和排出槽或通道的发散区域。
