Achieve Up To 95% Water Recovery!
What is Electrodeionization?
Electrodeionization also knowing is EDI or CEDI is a water treatment technology that utilizes DC electricity, ion exchange membranes and ion exchange resin to deionize water.
How Does Electrodeionization Work?
Water enters the Electrodeionization (CEDI/EDI) module, where electrical current is applied as a result it forces ions to move through the ion exchange resins and across the ion charged membranes… The ion exchange beds in the electrodeionized systems are regenerated continuously, also known as continuous Electrodeionization.

Complete Water Solutions Electrodeionization (EDI) water treatment technology removes not only residual salts but ionizable aqueous contaminants, like carbon dioxide, silica, ammonia, and boron. The systems operate chemical-free, achieve 95% water recovery, and consume only electricity. Our EDI systems provide key advantages over traditional ion exchange resin processes by using less energy consumption while yielding more ultrapure water.
Traditionally with ion filtration units, the pollutants and particles which get sorted out are trapped in the resin pores, leading to chronic buildup, and reducing filtration force. With an Electrodeionization system from Complete Water Solutions, the particles that are filtered through the membrane get entirely removed from the device by a consistent waste stream. By altering the filtration set-up, our systems allow the resins and water purification system to work at maximum capacity continuously. Keeping high purity water flowing and operating costs down.

EDI is used to polish off filtration and is used after a Reverse Osmosis System. The cleaner the water is when it reaches the EDI system, the longer the life span to expect.
