Abstract: An aqueous solution of a metal salt solution is converted to the corresponding acid by hydrogen ion substitution in a four compartment electrolytic cell containing three cation permselective membranes or barriers for defining the cell compartments. In one specific embodiment the salt solution initially treated in the intermediate compartment located adjacent to the cathode compartment is further treated by passing into the intermediate compartment located adjacent the anode compartment and thereafter removing the same as the final acid product. Such a flow arrangement prevents or reduces loss of hydrogen or citrate ions into the cathode compartment resulting in an increased acid yield with increased current efficiency.
Abstract translation: 金属盐溶液的水溶液通过氢离子取代在含有三个阳离子选择性选择性膜的四室电解池或用于限定电池室的阻挡层中转化为相应的酸。 在一个具体实施方案中，最初在位于阴极室附近的中间室中处理的盐溶液通过进入位于阳极室附近的中间隔室进一步处理，然后除去与最终酸产物相同的盐溶液。 这种流动装置防止或减少氢或柠檬酸根离子进入阴极室的损失，导致提高的电流效率提高了酸产率。

Abstract: An electrodeionization apparatus is provided for removing ions from liquids. Liquid to be purified is passed through at least two ion depletion compartments containing mixed anion and cation exchange resin beads in a given separation stage. A second liquid is passed through concentration compartments free of ion exchange resin beads. Ions under the influence of D.C. potential pass from the depletion compartments into the concentration compartments through ion permeable membranes. The beads in the depletion compartments are housed within subcompartments of controlled width and thickness and are retained therein by the ion permeable membranes which are secured to the walls of the subcompartments.
Abstract translation: 提供了用于从液体中去除离子的电去离子装置。 在给定的分离阶段，待纯化的液体通过含有混合阴离子和阳离子交换树脂珠粒的至少两个离子消耗室。 第二液体通过没有离子交换树脂珠的浓缩室。 在D.C.潜力的影响下，离子通过离子渗透膜从耗尽室进入浓缩室。 消耗隔间中的珠粒容纳在受控宽度和厚度的子隔室内，并通过固定到子隔室的壁的离子渗透膜保持在其中。

Abstract: A pretreatment step for the defouling of the compartments used in electrodeionization apparatus in which a solution of sodium percarbonate is contacted with the compartments to break up agglomerations of organic contaminants and colloidal films as well as to kill bacteria resident within the system. After this pretreatment step any conventional cleaning may be performed to complete the cleaning cycle.
