Water Treatment Plant Filter China Electrodeionization EDI System
1.Brief Introduction
EDI is a kind of pure water manufacturing apparatus that applies to ion exchange/ ion exchange membrane technology and ion electric migration technology. It is wisely combined electro dialysis with ion exchange technology, by using of high-voltage electrodes at both ends to drive charged ion in the water to move, and with the ion exchange resin and selective resin membrane to accelerate ions moving, so as to achieve the purpose of water purification. EDI has the features of easy operation and excellent environmental protection. It is a green revolution in high pure water producing.
