Electro Deionizer System

Electrodeionization is the chemical-free process in which ions are removed from water via electric potential. Ions are forced from the dilute compartments into adjacent reject compartments resulting in high purity water. This electric potential also constantly regenerates the resin in the module rather than conventional ion exchange units which use acid and caustic to regenerate.
EDI is currently designed to polish RO permeate (product).

EDI has significantly lower operating costs than conventional ion exchange processes. Only a relatively small amount of electric power is needed to provide high purity water. The lack of acid and caustic regeneration means less operator attention and lower labor costs. Capital costs can also expected to be lower, especially because no chemical storage, pumping and neutralization equipment is required.

EDI has a significantly smaller footprint than conventional ion exchange processes. This means less plant space will be required to provide the same quantity of water.
