Electrodeionization (EDI) GENERAL EDI, Electrodeionization is a membrane process that removes ions from the water to produce ultra pure water. EDI is comprised of ion exchange resin and membranes. The module gets a DC voltage applied across it to help drive the ions into the reject stream. Electrically-driven separation technology, such as electrodeionization (EDI), electrodialysis (ED), and electrodialysis reversal (EDR) use applied electrical potential to separate soluble ions and salts from a water or process stream. The separation occurs through a semi-permeable material, called an ion exchange membrane. Electrodialysis (ED) is used to transport salt ions from one solution through ion-exchange membranes to another solution under the influence of an applied electric potential difference. This is done in a configuration called an electrodialysis cell. The cell consists of a feed (dilute) compartment and a concentrate compartment formed by an anion exchange membrane and a cation exchange membrane ... Process water is water that is used for a variety of manufacturing processes, including: boiler make-up water; cooling tower make-up water; coating and plating; rinsing and spraying; washing and many others. Municipal or ground water supplies often contain dissolved minerals which can cause a multitude of problems than can affect product quality and manufacturing costs.

This combination along with EDI technology is designed to allow product water of less than 0.1 μS/cm to be obtained from 600 μS/cm raw water. In addition, the continual self-regeneration of the high purity EDI mixed bed resins affects a high microbiological purity of the product water at low operating costs.
