Twin-Stage Industrial RO EDI Water Treatment Plant System For Drinking

EDI system brief introduction

EDI ultra-pure water treatment equipment has the advantages of continuous effluent, no acid-base regeneration and no one on duty. It has been gradually replaced by mixing bed in the system of preparing pure water as the finishing equipment.

EDI ultra-pure water treatment equipment has good environmental protection characteristics, easy operation and use, and is more and more recognized by people. It is also more and more widely promoted in medicine, electronics, power, chemical industry and other industries.

EDI system Working principles editor

Electric deion (EDI) system is a kind of scientific water treatment technology which purifies the water quality through the selection and action of ion by exchange membrane.Electrodialysis device between a pair of electrodes, usually by Yin film, Yang film and the partition (a, b) multiple groups of alternating arrangement, constitute a concentrated chamber and a light chamber (that is, cations can pass through the Yang film, anions can pass through the Yin film).

Cationic ions migrate to the negative electrode in the fresh chamber and are trapped by the negative membrane in the concentrated chamber.Anionic migration towards the positive direction of Yin membrane in water, be strong chamber of Yang membrane intercept, such by light chamber on the number of ions in water gradually reduce, become fresh water, and thick the water chamber, due to the ion of Yin and Yang were strong chamber, dielectric ion concentration rising, become thick water, thus achieve the purpose of desalination, purification, concentration and refining.
