Electrodialysis Reversal (EDR)

Electrodialysis Reversal (EDR)

GE electrodialysis reversal systems, pioneered by Ionics, suit multiple applications, including:

	Reducing radium, arsenic, perchlorate, fluoride, nitrate, hardness, uranium and selenium in drinking water
	Recycling municipal and industrial wastewater
	Recovering reverse osmosis reject
	Desalting well and surface waters
	Desalting water for boiler makeup and other industrial uses

GE systems achieve up to 94 percent water recovery while removing 40 to 90 percent of total dissolved solids. Our stacks have a long operational life and can be manually separated, cleaned and reused. Systems can handle high silica feeds – up to 140 ppm – reducing chemical usage and lowering costs. Our disinfectiontolerant membranes can operate with chlorine up to 0.5 ppm continuously and from 25 to 50 ppm during spikes.

Benefits To You

	High water recovery design efficiently processes a source water and generates low concentrate volume for disposal.
	Rugged systems are less sensitive than reverse osmosis (RO) to particulates and metal oxides.
	Long membrane life (typically 10 years) lowers the cost of ownership.
	Chlorine-resistant membranes are tolerant to disinfection, allowing use on challenging waters.
	Reclaim waste waters to reduced waste discharges and reduce water use charges.
	Easily control salt removal and product quality by adjusting amount of electricity applied to membrane stack.
