Cyclic Ion Exchange (CIX-RO)

Cost-effectively soften your process water by regenerating your resin for free with RO reject stream

The CIX-RO design combines two key technologies: cyclic ion exchange (CIX) and reverse osmosis (RO). Designed and patented by one of our suppliers, Purolite, the CIX system consistently removes up to 95% of water hardness while using 90% less salt than typical softening systems. 

The softened water is then fed into a Kontek RoKon reverse osmosis system for recovery. The RO’s reject brine water is then fed back into the CIX resin chambers. Instead of purchasing, storing and hauling mountains of regenerant salt, the streamlined CIX-RO design lets you cost-effectively reuse your RO’s salty brine water for resin regeneration.
