简介:

      EDI是一种将离子交换技术、离子交换膜技术和离子电迁移技术相结合的纯水制造技术。它巧妙的将电渗析和离子交换技术相结合,利用两端电极高压使水中带电离子移动,并配合离子交换树脂及选择性树脂膜以加速离子移动去除,从而达到水纯化的目的。

Brief introduction:

      EDI is a kind of pure water manufacturing technology which combines ion exchange technology, ion exchange membrane technology and ion exchange technology. It cleverly the electrodialysis and ion exchange technology combination, using electrodes at both ends of the high pressure of the movement of charged ions in water, and with the ion exchange resin and the selectivity of the resin film to accelerate the mobile ions removal, so as to achieve the purpose of purified water。

工作原理

      (1)水进入 EDI 系统,主要部分流入树脂 / 膜内部,而另一部分沿模板外侧流动,以洗去透出膜外的离子。

      (2)树脂截留水中的溶存离子。

      (3)浓缩了的离子从废水流路中排出。

      (4)无离子水从树脂 / 膜内流出。

      (5)无离子水从树脂 / 膜内流出。

 

working principle:

      (1)Water into the EDI system, the main part of the flow into the resin / film inside, while the other part of the flow along the outside of the template, to wash away from the outside of the membrane。

      (2)The soluble ions in the water。

      (3)The cation is through a cation membrane, which is discharged from the resin / film。

      (4)he concentration of ions is discharged from the waste stream。

      (5)No ion water flows out of the resin / film。

设备优点

      (1)水质稳定

      (2)容易实现全自动控制。

      (3)不会因再生而停机。

      (4)不需化学再生。

      (5)运行费用低。

Equipment advantages

      (1)Stability of water quality

      (2)Easy to implement automatic control。

      (3)Will not be shut down due to regeneration。

      (4)Chemical regeneration is not required。

      (5)Low operating cost。
