Electrodeionization Stacks

The EDS-Series elements are known as "stacks". These stacks are designed to remove cations and anions (minerals) from pretreated water with less than 40 microS/cm, 1ppm silica, .01 ppm iron, .02 ppm total chlorine/chloramine, 1.0 ppm of hardness and .05 ppm of dissolved oxygen. The EDS-Series modules are designed to remove ions, and reduce TOC.
