Introduction
The water after preceding treatment can not meet the requirements for purity of craft water, thus adding the EDI system to desalinate in further.
EDI system is made up of middle pump and EDI plant:
EDI is one kind of new desalination technology integrates electrodialysis and ion exchange, its English name is ectrodeionization, and initials is EDI, the craft integrates the advantages of electrodialysis and ion exchange, and makes up for the disadvantages of them above, namely use ion exchange deep desalination to overcome the inexhaustive desalination of electrodialysis, and use electrodialysis polarization to produce H+ and OH-to achieve resin rebirth, thus overcoming the defects of rebirth via Chemical reagent. so EDI is one perfect treatment technology. With advantages below:
1) high producing water(output water) purity.
2) stable output water quality.
3) exchange end is obvious.
4) discontinuous operation has little effect on output water quality.
Advantages and Characteristics
1.Higher producing water quality.
2.High rate of desalination.
3.Utilization rate reach up over 95%.
4.Resin doesn’t need to regenerate.
5.Convenient :running\operation\maintenance.
6.It has standard design, Module can be piled according to requirements of proudcing water,to adapt requirements of more water production.
7.It has Low operating cost,low consumption,when produce 3.8m3,it costs 1KW.
