The first and second diluting compartments are bounded by an anion exchange membrane on the side closest to the anode and by a cation exchange membrane on the side closest to the cathode. The first and second concentrating compartments are bounded by a cation exchange membrane on the side closest to the anode and by an anion exchange membrane on the side closest to the cathode.

摘要： A spiral electrodeionization device comprising flow paths within helical cells, which form a path-lengthening maze. Impermeable barriers between membranes prevent the feed and concentrate flows from mixing. Seals along or between portions of the flow path may define a multi-stage device, a separate feed device and /or concentrate flows for different stages, and/or direct the feed and concentrate flows along preferred directions which may be co-current, counter-current or cross-current with respect to each other. Bands (BB) in the concentrate compartments may channel scale-forming species along separate paths in different regions so that scaling does not occur, and the separation of species may be enhanced by arranging the feed flows along an axial direction through layers of different monotype resins that enhance species transport into one region of the concentrates and/or inhibit transport of the complementary sealant species in that region.

摘要： An electrodeionization, (EDI) apparatus has flow cells with a sparse distribution of ion exchange (IX) material or beads. The beads extend between membranes defining opposed walls of the cell to separate and support the membranes, and form a layer substantially free of bead-to-bead dead-end reverse junctions. The beads enhance capture of ions from surrounding fluid in dilute cells, and do not throw salt when operating current is increased. In concentrating cells, the sparse bead filling provides a stable low impedance bridge to enhanced power utilization in the stack. A monotype sparse filling may be used in concentrate cells, while mixed, layered, striped, graded or other beads may be employed in dilute cells. Ion conduction paths are no more than a few grains long and the lower packing density permits effective fluid flow. A flow cell thickness may be below one millimeter, and the beads may be discretely spaced, form a mixed or patterned monolayer, or form an ordered bilayer, and a mesh having a lattice spacing comparable to or of the same order of magnitude as resin grain size, may provide a distributed open support that assures a stable distribution of the sparse filling, and over time maintains the initial balance of uniform conductivity and good through-flow. The cells or low thickness and this resin layers relax stack size and power supply constraints, while providing treatment efficiencies and process stability. Reduced ion migration distances enhance the ion removal rate without reducing the product flow rate. The sparse resin bed may be layered, graded along the length of the path, striped or otherwise patterned. Inter-grain ion hopping is reduced or eliminated, thus avoiding the occurrence of salt-throwing which occurs at reverse bead junctions of prior art constructions. Conductivity of concentrate cells is increased, permitting more compact device construction, allowing increases in stack cell number, and providing more efficient electrical operation without ion additions. Finally, ion storage within beads is greatly reduces, eliminating the potential for contamination during reversal operation. Various methods of forming sparse beds and assembling the stacks are disclosed.
摘要翻译：电去离子（EDI）装置具有离子交换（IX）材料或珠的稀疏分布的流动池。珠粒在限定细胞的相对壁的膜之间延伸以分离和支撑膜，并且形成基本上没有珠粒到珠粒死端反向连接的层。珠增强了稀释细胞中周围液体的离子捕获，并且在工作电流增加时不会引起盐。在浓缩电池中，稀疏珠填充提供了稳定的低阻抗桥，以增强堆叠中的功率利用率。可以在浓缩细胞中使用单倍稀释填充物，而稀释细胞中可以使用混合，分层，条纹，分级或其它珠粒。离子传导路径不超过几个颗粒长度，较低的填充密度允许有效的流体流动。流动池厚度可以低于1毫米，并且珠可以离散地间隔开，形成混合或图案化的单层，或形成有序的双层，以及具有与树脂颗粒相当或相同数量级的晶格间距的网尺寸可以提供分布式开放支撑，其确保稀疏填充物的稳定分布，并且随着时间的推移维持均匀导电性和良好通流性的初始平衡。细胞或低厚度以及这种树脂层可以缓解堆叠尺寸和电源限制，同时提供处理效率和工艺稳定性。降低离子迁移距离可以提高离子去除率，而不会降低产品流速。稀疏的树脂床可以层叠，沿着路径的长度分级，条纹化或以其他方式图案化。颗粒间离子跳跃被减少或消除，从而避免了在现有技术结构的反向珠缘接合处发生的盐滴的发生。增加浓缩池的电导率，允许更紧凑的器件结构，允许增加堆叠电池数量，并且提供更有效的电气操作而不需要离子添加。最后，珠子内的离子存储大大减少，消除了反转操作期间的污染潜力。公开了形成稀疏床和组装叠层的各种方法。
