500L/H EDI Water Treatment System

EDI system introduction

After frontal treatment, the water can not meet the purity requirements of craft water, thus to add the EDI to desalinate salt 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 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.

Technical Parameters

1, Inlet water parameters:
1) Inlet water: RO water
2) Inlet water quality: 20uS/cm
3) Working (water) Temperature: 5-35隆茫C

2, Design Technical Parameters
According to User隆炉s requirements and conditions of inlet water, we have designed water treatment parameters as follow:
1)   Water production: 500 liters per hour
2)   Water pressure: 0.25-0.5Mpa
3)   Recovery rate: 隆脻90%
4)   Design process (making water process):

The producing water fits for the standards of National 1st Type laboratory water (GB/T6682-200) and National electronic ultrapure water standards (GB/T11446.1-1997).
