Description
EDI (electrodeionization)
super pure water equipments is a deep desalination device, with
treating the supply water of power plant according to the EDI
technology. The EDI is core technology of preparation pure water
and super pure water. It mix together the technology of
electrodialysis and ion exchange. The function combine selective
permeability which realized by exchange membrane of cation and
anion and exchange interaction which realized by ion exchange resin
make the ion directional migration under DC field. Though this
process the supply water can be deep desalted and the yield water
can amount to *5M&branded;.cm. Accompanying the
desalination, the hydrion (H+) and hydroxyl (OH-) produced by water
ionized can make the ion exchange resin regenerate. So the yield
water can produced continuously with no acid-alkali chemical
regeneration.
Characteristic:
1. High quality and stability of the yield
water.
2.High rate of desalination
3.Utilization rate reach up over
*5%
4.Resin doesn't need to
regenerate
Advantage：
A) The system can produce the
pure water continuously and not for regenerate to
stop.
B) No chemical agent
regenerate.
C) Considerate stackable
design, Small floor area.
D) Easy operate, Perfect
security.
E) Operation costs and
maintenance cost low.
F) No reserve of acid and
alkali and transport cost.
G)The whole desalination
system is automatic operation and need no special person. It has
unmatchable advantage over the other system. The system is widely
used in preparation of pure water and super pure
water.
