    摘要： A method and apparatus is provided for inhibiting scaling in an electrodeionization system and, more particularly, for increasing tolerance to hardness in the feed water to an electrodeionization unit by inhibiting precipitation of scale-forming metallic cations contained in the feed water and thereby increasing efficiencies of the electrodeionization system. Water to be purified is passed through an electrodeionization unit in which the flow in the diluting compartment is countercurrent to the flow in the concentrating compartment. This is to impede the migration of scale-forming metallic cations from the diluting compartment, through the cation exchange membrane, into the concentrating compartment and towards the concentrating compartment side of the anion exchange membrane, thereby preventing scale formation on the anion exchange membrane. The electrodeionization unit may be further modified by dividing the concentrating compartments into first and second compartments by a porous diaphragm or ion-conducting membrane. The porous diaphragm or ion-conducting membrane effectively eliminates convective transport of scale-forming metallic cations from the cation exchange membrane side of the concentrating compartment to the anion exchange membrane side of the concentrating compartment, thereby inhibiting scale formation on the anion exchange membrane.

    摘要翻译： 提供了一种用于抑制电去离子系统中的结垢的方法和装置，更具体地，通过抑制进料水中包含的形成规模的金属阳离子的沉淀，增加对去电单元的给水中的硬度的耐受性，从而提高 电去离子系统。 待净化的水通过电去离子单元，其中稀释室中的流动与浓缩室中的流动逆流。 这是为了阻止鳞片形成金属阳离子从稀释室通过阳离子交换膜迁移到浓缩室中并朝向阴离子交换膜的浓缩室侧迁移，从而防止阴离子交换膜上的结垢形成。 可以通过多孔隔膜或离子传导膜将浓缩室分成第一和第二隔室来进一步修改电去离子单元。 多孔隔膜或离子导电膜有效地消除了形成规模的金属阳离子从浓缩室的阳离子交换膜侧到浓缩室的阴离子交换膜侧的对流传输，从而抑制阴离子交换膜上的结垢。

In the case where the one of the anion permeable membrane and the cation permeable membrane, having the at least a portion of an ion-concentrating compartment side surface with which the first ion exchange material domain is contiguous, is an anion permeable membrane, the first ion exchange material domain is an anion exchange material predominant domain. In the case where the one of the anion permeable membrane and the cation permeable membrane, having the at least a portion of an ion-concentrating compartment side surface with which the first ion exchange material domain is contiguous, is a cation permeable membrane, the first ion exchange material domain is a cation exchange material predominant domain.
