Ionics Incorporated now offers the DeltaFlow® 2.0 system for producing ultrapure water without the use of hazardous ion exchange regeneration chemicals. This unique system combines three membrane separation technologies, RO, GTM® membrane degasification and electrodeionization in a space-efficient design for continuous production of ultrapure water. Originally produced in 1997, the DeltaFlow 2.0 system utilizes a host of improvements over its predecessor and is offered under build-own-operate contracts with Ionics.
