Electropure™: Electrodeionization

“Electropure EDI is Simple EDI.”

SnowPure's Electropure™ EDI products

SnowPure’s Electropure electrodeionization products are used worldwide in ultrapure water systems in a diverse range of applications, including pharmaceutical, semiconductor, power generation and laboratory pure water systems.

Electrodeionization (EDI) is a process by which an electric field is used to remove ions and polar species from an aqueous stream. EDI is used with reverse osmosis (RO) to replace ion exchange resin-mixed beds (MBDI), which require onsite or offsite chemical regeneration.

By eliminating the batch process resin regenerating chemicals, EDI delivers significant economic and environmental benefits. Electrodeionization, a continuous process, improves water consistency by reducing water quality spikes and upsets.

SnowPure sells EDI modules to qualified OEMs and pure water system integrators. Because SnowPure only sells the components for ultrapure water systems, and not the systems themselves, we do not compete with the OEMs we serve.

Request a QuoteSnowPure also offers a free EDI training course for customers, which covers all aspects of Electrodeionization, ranging from fundamental principles and system design considerations to hands-on operation and maintenance. Completing this training is the first requirement to become a Qualified SnowPure OEM customer.
