Flysheet: Regeneration as a Service

For municipal and private water systems, single-use media can make emerging contaminant treatment costly and waste-intensive. SORBIX™ RePURE, an Onterris proprietary regenerable ion exchange (IX) resin process, supports lower PFAS lifecycle costs better than alternative options, without adding infrastructure or operational complexity.

Flysheet: FOAM-X

Landfills face increasing complexity from PFAS contamination in leachate. Onterris offers FOAM-X, our foam fractionation technology, to remove and concentrate PFAS and support proactive leachate management that reduces risk and supports meeting compliance requirements.

Flysheet: SORBIX REPURE

Per- and polyfluoroalkyl substances (PFAS) are extremely resistant to breakdown and are difficult to capture using traditional treatment methods. SORBIX™ RePURE offers an advanced ion exchange resin solution which is adaptable to diverse water matrices, providing effective treatment for industrial wastewater, municipal water supplies, and environmental remediation projects.
