The detailed working principle of water production equipment EDI and what should be noted when running

edi is the mixed bed and electrodialysis into one ultrapure water equipment. By direct current electrolysis of water molecules, hydrogen ions and hydroxide ions, and then regenerate the failed anion and cation resin. In this way, the resin in edi can be used for a long time without the need for acid and alkali regeneration like mixed bed. Operation should pay attention to the first, oxygen ions in the feed water, chloride ions can not be detected. I have repaired most of the edi because the resin oxidation pressure difference, flow rate is small. Second, produced water, concentrated water, water in the absence of flow or flow rate is very small in the case of strictly prohibited power. It will burn the resin inside, the diaphragm, and even the outer frame, and there is no value of repair again.
