External UPW resin regeneration is key to good quality water production, ensuring chemicals do not enter the process stream during mixed bed resin regeneration. Ovivo by Ecolab SepIX is a simple and cost-effective mixed bed external single regeneration column technology that provides flexible and efficient UPW resin regeneration.

Ovivo by Ecolab SepIX is typically used where the mixed bed ion exchange resins regeneration are of fixed ratio and volume and where high-quality water is required. The SepIX system also removes suspended solids that have been trapped in the resin during service.

External regeneration of resins has the advantage of very low cross-contamination of the ion exchange resins. By regenerating the resin externally, the physical separation of the operating and chemical handling systems eliminates the risk of chemicals entering the UPW circuit. One central mixed bed external single regeneration unit can serve several mixed bed vessels.

Ovivo by Ecolab SepIX offers a range of benefits, such as:

• Consistently high purity water.
• Reduced risk of chemicals contaminating product water.
• Robust proven design.
• Fully automated operation.
• Single vessel regeneration system that reduces costs.
• Isolation of the intermediate cross-contaminated resin layer.
• Reduced rinsing time due to high regeneration level.
• Effective resin cleaning to remove solids trapped in the resin bed.
• Flexible skidded designs.
• Compact footprint.
• Retrofitting option for existing plants.
