Electrodeionization (EDI) Water Treatment

Focus on your core business while GE runs your water plant

Remove residual salts and other aqueous species from your water with up to 18 MOhm-cm resistivity

GE’s E-Cell* electrodeionization (EDI) technology removes residual salts and ionizable aqueous species - such as carbon dioxide, silica, ammonia and boron - from your water sources. The EDI systems operate chemical-free, achieve 97% water recovery, and consume only electricity. They are ideal for multiple applications including: power generation for boiler feed and NOx control, semiconductors, microelectronics, food and beverage, and pharmaceuticals.

E-Cell EDI Features

GE’s EDI systems provide key advantages compared to traditional ion-exchange processes:

  • Eliminates expensive and hazardous chemicals used in ion-exchange resin regeneration
  • Reduces energy and operating expenses
  • Reduces the facility size requirement
  • Helps plants meet ISO14000 requirements
