Green technology solutions have become a necessary part of our everyday lives.  The power of green represents Siemens’ emphasis on unmatched, innovative water and wastewater solutions that allow you to make environmental sustainability a common business practice.

Under the Ionpure® brand, Siemens Continuous Electrodeionization (CEDI) modules are the most advanced generation of Ion Exchange technology.  Our products are environmentally friendly, operate with continuous production, and have extremely low operating costs when compared to chemically regenerated ion exchange technology.

Currently, there are three lines of electrodeionization modules available: the VNX, the LX and the MX series. We also offer supplementary equipment ranging from DC Power Controllers to Piping Adapters to fit your system requirements.


What is Continuous Electrodeionization (CEDI)?

Continuous Electrodeionization (CEDI) is a chemical-free process that uses ion exchange resins and electricity to produce ultra-pure deionized water.  CEDI utilizes no chemical regenerants and creates no hazardous wastes.  The ion exchange resins are used primarily as a bridge to allow electric current to pass through the electrodeionization cell - this allows the modules to operate without any brine injection or concentrate recycle.

Also, the ion exchange resins are used to "polish" the purified water stream by removing minute quantities of silica, carbon dioxide and other contaminants.  Additionally, the resins are continually regenerated by the dissociated hydrogen and hydroxyl ions that have been created by the electric current.
