ABOUT CYCLOPURE
Cyclopure is a leading PFAS treatment company built around one breakthrough: DEXSORB®, the first-ever fully regenerable, PFAS-selective adsorbent engineered specifically for engineered water systems.
Unlike conventional technologies that rely on non-selective adsorption, DEXSORB is designed at the molecular level to target PFAS directly. Its uniform cyclodextrin cavities selectively bind PFAS, enabling removal to non-detect levels with higher capacity, faster kinetics, and greater resistance to interference from organic matter and dissolved ions. The result is longer run times, fewer changeouts, and more reliable performance across drinking water, groundwater, wastewater, and industrial applications.
DEXSORB consistently outperforms legacy media such as granular activated carbon and ion exchange, delivering 3–4x higher capacity, significantly shorter empty bed contact times, and reduced system footprint. For utilities and engineers, this translates into lower capital requirements, reduced operational burden, and lower cost per gallon treated.
Cyclopure is also among the only companies offering regenerable PFAS-selective media that restores performance while concentrating PFAS into a manageable waste stream. This capability reduces disposal volume, extends media life, and supports a more cost-effective and responsible treatment approach.
With deployments across municipal, industrial, and remediation sites worldwide, DEXSORB is proven in real-world conditions, not just controlled environments.
Built for PFAS. Proven to non-detect.
Cyclopure enables engineered systems to achieve higher performance, longer life, and greater certainty in PFAS treatment.
SCIENTIFIC EXPERTISE
Modern water treatment demands highly selective adsorbents to combat complex PFAS contamination. By leveraging dual-action molecular cavities, these stable polymers provide rapid kinetics, resist organic fouling, and support sustainable regeneration for superior environmental remediation.
DEXSORB is a regenerable adsorbent media offering a cradle-to-grave solution in per- and polyfl uoroalkyl substances (PFAS) treatment. Effective desorption of PFAS from spent media is not only a critical step for enabling sustainable media reuse, but also for concentrating PFAS waste for its safe and cost-effective destruction.
DEXSORB is a novel adsorbent made from crosslinked β-cyclodextrin polymers. The media features uniform 0.78 nm hydrophobic cavities that selectively adsorb organic contaminants in the 150 – 1000 Dalton molecular weight range. DEXSORB is available in two formulations to adsorb (A) PFAS exclusively, or (B) PFAS + organic micropollutants (OMPs) in combination. While DEXSORB and GAC operate by the same mechanism of adsorption, and share similar physiochemical properties, DEXSORB possesses multiple properties that provide for superior PFAS removal and waste handling.
CASE STUDIES
A DWTP client in Alaska detected elevated PFAS contamination levels in two groundwater wells supplying drinking water to 85 service connections. PFAS concentrations are provided in Table 1, where combined concentration of EPA PFAS6 was detected at 490 to 810 ppt.
Cyclopure was invited to replace ion exchange resin to remove PFAS from groundwater at a groundwater pump station, located in NJ. The decision to replace IXR was due to poor PFAS removal caused by manganese fouling.
A metal plating service provider detected twelve PFAS at a total concentration of 36,704 ppt in the fi nal process water at its Michigan facility. PFOS was detected at 840 ppt on average, in excess of the city PFOS discharge limit of 28 ppt. The facility utilizes coagulation and sedimentation process to remove metals and requires PFAS treatment prior to discharge to the city’s sanitary sewer.
