PFAS Treatment Solutions and Removal

DEXSORB® is a selective, regenerable adsorption media that removes both short- and long-chain PFAS from water. Available through Kurita's partnership with Cyclopure, Kurita delivers advanced PFAS treatment and PFAS removal solutions with a sustainability profile conventional media can't match.

• Broad-spectrum removal, including short-chain compounds and replacement compounds like GenX
• High capacity versus granular activated carbon
• Regenerable & reusable to reduce waste and lifecycle cost
• Certified destruction pathway

Granular activated carbon is a proven, widely accepted adsorption technology for PFAS removal, well-suited to certain long-chain PFAS applications. As part of Kurita's full portfolio, we deploy GAC where it's the best-fit or complementary solution within a PFAS water treatment system.

• Established, regulator-familiar technology for long-chain PFAS
• Coincidental removal of other contaminants of concern

Ion exchange resins and novel media adsorbents remove PFAS through selective molecular attraction and are effective for targeted compounds. Kurita applies the appropriate adsorption technology based on selectivity and available configurations to deliver the best value for a given water chemistry.

• Strong selectivity for certain PFAS compounds
• Compact footprint and flexible deployment

Reverse osmosis physically separates PFAS from water and is highly effective for concentration and reuse applications. Because reverse osmosis PFAS systems deliver high removal, it protects the finished water and allows for management of the PFAS-concentrated reject stream with downstream PFAS treatment technologies. Reverse osmosis PFAS solutions are often integrated with other PFAS removal technologies to remove PFAS from water reliably and manage treatment residuals.

Kurita provides complete, verified destruction of captured PFAS residuals using PFAS destruction technologies following off-site regeneration of DEXSORB. This eliminates recontamination risk and long-term liability, supporting comprehensive water treatment for PFAS. The captured PFAS is destroyed off-site and a certificate of destruction is provided, so utilities and facilities aren't left managing long-term residual liability.

Kurita engineers and delivers complete PFAS water treatment system solutions and supports them for the life of the asset. Our team designs new systems or retrofits existing ones, integrating PFAS removal solutions with broader water treatment programs.

Kurita helps municipalities and water utilities meet tightening PFAS drinking water regulations with proven, compliance-ready treatment. The regulatory landscape for PFAS in drinking water is moving quickly, and Kurita translates evolving requirements into a clear, defensible compliance path, performing system audits and feasibility assessments to recommend the most effective, lowest-lifecycle-cost solution for each utility's source water and treatment targets.

PFAS removal is the process of capturing per- and polyfluoroalkyl substances (sometimes called "forever chemicals") from drinking water, process water, or wastewater and then destroying the captured residuals so they don't re-enter the environment.

The main effective options include regenerable DEXSORB adsorption, GAC, IX, and reverse osmosis PFAS systems. The best PFAS removal solution depends on the types of PFAS present, water chemistry, flow rate, and available footprint. Kurita selects from these PFAS removal technology options to integrate a cohesive PFAS water treatment system to remove PFAS from water and meet regulatory targets.

Activated carbon effectively removes PFAS through adsorption: PFAS molecules adhere to the carbon’s porous surface. GAC excels with many long-chain PFAS but can be less effective on short-chain compounds and may require more frequent change-out. In some cases, GAC may be paired with other PFAS treatment technologies for comprehensive water treatment for PFAS.

While rejection may vary among species, RO provides broad physical separation and can significantly reduce both long-chain and short-chain PFAS. However, RO creates a PFAS-concentrated reject that may require downstream PFAS treatment and residuals handling. Combining reverse osmosis PFAS systems with adsorption or other treatment solutions ensures comprehensive control of residuals.

DEXSORB is a selective, regenerable adsorbent made from renewable corn-based chemicals. It acts as a molecular sieve that removes both short- and long-chain PFAS while rejecting co-contaminants through molecular size exclusion. DEXSORB offers 4 to 10x the capacity of GAC at a fraction of the contact time, requiring a smaller footprint. The media is fully regenerable, producing a concentrated liquid waste ready for destruction through accepted methods. This reduces lifecycle cost and waste compared to conventional solutions.

PFAS captured by the DEXSORB media is concentrated during the off-site regeneration process. The liquid waste is destroyed using a certified method, and Kurita provides a unique certificate of destruction. This cradle-to-grave approach ensures contaminants are permanently eliminated rather than stored or landfilled.

Yes. Kurita serves municipal drinking water and industrial potable and wastewater needs – including semiconductor, food & beverage, and solid waste – with solutions engineered to each customer's regulatory targets and operations.

Yes. DEXSORB is NSF-approved for use in drinking water applications.

Utilities can meet the NPDWR limits for PFAS by installing proven adsorption or separation treatment – such as DEXSORB regenerable media, surface modified clay, granular activated carbon, ion exchange, or reverse osmosis – matched appropriately to their specific source water, flow, and treatment goals. Kurita helps utilities select and engineer the right solution, treat to the required maximum contaminant levels, and destroy captured PFAS with a certificate of destruction for full cradle-to-grave compliance.
