Ultrapure water equipment consists of what systems?

The EDI module of the ultrapure water equipment consists of alternately placed cation and anion membranes, these alternately placed anion and cation exchange membranes are fixed between two devices with inlet and outlet ports, and water flows through the membrane gap therein. The anion membrane facing the positive pole and the cation membrane facing the negative pole form a concentrated water chamber, the anion membrane facing the negative pole and the cation membrane facing the positive pole form a fresh water chamber, and the anion/cation electrodes are provided at both ends of the unit group.

Ultra-pure water equipment

Two, ultra-pure water equipment working principle

Ultra-pure water equipment system work, in the DC drive, through the fresh water chamber water flow of anions and cations through the anion and cation exchange membrane into the concentrated water chamber and in the freshwater chamber to remove the water chamber, and through the concentrated chamber of the water will be the ions out of the system to become concentrated water. Ultrapure water equipment generally reverse osmosis water as the feed water for ultrapure water equipment, RO water conductivity is generally 2 ~ 4O bcS/cm (25 ℃).

Ultra-pure water resistivity can be as high as 18MΩ-cm, but according to the use of deionized water and system configuration settings, the conductivity of purified water according to the different uses of purified water should be controlled in the 1 ~ 2 ~ S/cm. ultrapure water equipment is suitable for the preparation of resistivity requirements of the purified water in the range of 1 ~ 18MΩ-cm
