Portable Exchange Deionization

The two basic configurations of Deionization Systems are separate-bed and mixed-bed.

Separate-bed deionization systems have separate tanks of cation and anion resins. In Mixed-Bed deionization systems, the anion and cation resins are blended at a 60/40 percentage split into a single vessel. Generally, mixed-bed systems will produce higher quality water with a lower total capacity than two-bed systems.

Deionization can produce ultra high-purity water in terms of dissolved ions or minerals, up to the maximum resistance of 18.2 MΩs/cm. However, they do not generally remove organics and can become a breeding ground for bacteria, actually diminishing water quality where organic and microbial contaminations are critical.

Failure to regenerate the deionization resins at the proper time may result in harmful salts remaining in the water or even worse, being increased in concentration. Partially exhausted deionization resin beds can increase levels of contaminants due to the resin’s selectivity for specific ions, and may add particulates and resin fines to the deionized water.

We can help with your Deionization projects. When you call for assistance with your Deionization project, a State of Texas Certified Water Treatment Specialist will make a site visit we will ask what are the Dissolved minerals in your incoming water. If you do not know we have a simple form you can submit to your local test laboratory to get you the right information to begin work on your Deionization system.
