Introducing C-EDR

A Breakthrough Desalination Technology

C-EDR is a proprietary, breakthrough desalination technology that requires significantly less energy compared to the most efficient desalination systems on the market.

C-EDR or Capacitive Electrodialysis Reversal was developed by Ionic Solutions and is an exciting new technology for desalinating water. This process reduces the cost of water by 30%*, a major improvement over reverse osmosis (RO) and other systems. C-EDR offers:

    • 50% lower energy*
    • 55% higher recovery*
    • 80% lower chemical and maintenance costs*

Th C-EDR solution is ideal for many applications including brackish, seawater, ultrapure and water softening. This technology can be added to existing facilities requiring additional water treatment capacity or brine reduction.

*Compared to conventional seawater reverse osmosis desalination.

Improved Performance

Innovative Ion Separation Process

C-EDR’s improved performance is based on our innovative ion separation process. Highly charged capacitive electrodes efficiently remove ions from the water. The system self-cleans as the charge continuously reverses directions. Novel features in the membrane system results in high separation efficiency. As a result, C-EDR outperforms RO technologies, and overcomes the limitations of both conventional ED and EDR technologies.

Cities, towns, and villages

Ionic Solutions C-EDR technology is ideally suited for the desalination of water for any size of residential community. Our base unit of 100 m3/day can provide potable water for 300 to 600 residents depending on location and consumption needs. Larger communities of towns or cities can be serviced by stacking base units to get the flow rate that is required.


Our C-EDR technology is capable of desalinating oilfield produced water with very high salinities. Such high salinity waters could not be treated with RO. This is an opportunity to desalinate water for use in the hydraulic fracturing industry, steam generation industry or secondary recovery waterflood projects.

Ultrapure Residential or Home Use

The amount of ion removal from water can be customized using the Ionic Solutions C-EDR technology. Generally, some ions are left in the water as a health benefit for human consumers. This solution will apply to the bottle water industry or beer brewing industry. However, some industries, such as Pharmaceuticals or chemical manufacturing may require water with very few ions remaining in solution. This ultra-pure water can be provided using our C-EDR technology.



of the earth’s water can be used for human consumption and agriculture without further processing. This leaves many parts of the world reliant upon desalination of seawater for domestic purposes.
