Continuous Deionization (CDI)

Deionization is the process of removing ions from water, most commonly through an ion exchange process.

CDI Technologies
We offer electrodeionization, mixed and packed bed systems. Our CDI® (Continuous De-Ionization) system is a chemical-free process for producing high-purity water using ion exchange membranes, resins and electricity. The absence of chemicals makes this a popular process for general industry, pharmaceutical and microelectronics use.

Continuous Deionization Case Study

Biopharm Company Upgrades 2-pass Reverse Osmosis System to Improve Quality of USP Purified Water

A veterinary pharmaceutical firm in the Midwest upgraded a USP Purified Water system that was not consistently producing water of adequate quality – both conductivity and microbial.  The customer did not want to use chemicals to regenerate ion exchange beds and is located far from any service deionization facilities.
