Continuous Deionization (CDI) Technologies

Deionization is the process of removing ions from water. Our CDI® (Continuous De-Ionization) system is a chemical-free process for producing high-purity water using ion exchange membranes, resins and electricity.

Continuous Electrodeionization (CEDI/EDI)

Continuous Electrodeionization (CEDI) is your safe, chemical-free way to take RO (Reverse Osmosis) water to a higher level of purity. Under the Ionpure® brand, Evoqua's CEDI modules are the most advanced generation of Ion Exchange technology.


We offer complete Ion Exchange Deionization systems to produce pure water for rinsing, boiler feed or any other application. These systems are quality engineered and manufactured to produce the quantity and quality of water needed for your application.

Ion Exchange Resins - Cation, Anion & Specialty

Our USF™ ion exchange resins are produced by the leading manufacturers to meet our stringent, performance based specifications. Our high standards assure that USF™ resins are the highest quality product and also, most competitively priced.


Ion exchange water softening removes calcium and magnesium to produce softened water. Unlike hard water, softened water will not leave any residue or scale on things it comes in contact with.
