Electrodialysis Electrodialysis Reversal EDI Pure Water Making

The benefits and advantages of using EDI compared to the traditional ion exchange process are:

Operates continuously, no downtime for regenerations

Eliminates regeneration chemicals

Reduces energy, operating and maintenance expenses

Minimizes space requirement

Enables a simpler system (no concentrate recirculation) and fully shop assembled on skids to minimize site work

They are ideally used in power generation for boiler feed water and NOx control, semiconductors, microelectronics, laboratory and pharmaceutical application

Feed water requirement

Resource: RO water, conductivity < 20 u s/cm, better < 10u s/am;
PH:6.5-9.0
