Puraffinity

What Puraffinity does

Puraffinity is a London-based, privately held materials science company founded in 2015 as a spin-out from Imperial College London. It develops and manufactures Puratech, a proprietary surface-engineered adsorbent media platform (current generation: Puratech G400+) designed to selectively capture short- and long-chain PFAS compounds from water. The technology is delivered as a customizable plug-in media that integrates into existing water treatment systems, with reported performance of up to 7x the capacity of petroleum-derived ion exchange resins, contact times reduced from 24 to roughly 1 minute, and a 60% lower manufacturing carbon footprint per a 2022 Systemiq assessment. G400+ is certified to NSF/ANSI/CAN 61 and NSF/ANSI/CAN 372 for Point of Entry and Water Treatment Plant end uses.

The company serves five end markets: municipal water utilities, industrial facilities (including airports and military sites with AFFF contamination), environmental service providers, commercial/institutional customers, and residential applications. Revenue is generated primarily through sale of adsorbent media for initial system deployment and ongoing replacement cycles, supplemented by technology licensing and co-development arrangements such as the U.S. Army ERDC CRADA. Distribution combines direct enterprise sales with a system-integrator and channel-partner model (e.g., Giotto Water in Italy, Envytech Solutions in the Nordics), with manufacturing currently delivered through a tolling network in the UK and Germany while in-house capacity is built out. Puraffinity completed a £16.93M Series A in September 2024, is led by CEO Vincent Caillaud (former CEO of Veolia Water Technologies & Solutions), and has grown headcount to roughly 40 employees focused on transitioning from an R&D-led entity to a full commercial operation.

Core offering

Puraffinity develops and manufactures proprietary Puratech adsorbent media (G400+) engineered with patented surface chemistry modification to selectively capture short- and long-chain PFAS contaminants from water. The media is supplied as a customizable plug-in component for integration into existing water treatment systems and is sold to municipal water utilities, industrial operators, environmental service providers, and commercial/residential filtration manufacturers. The company also pursues technology licensing and collaborative research arrangements (e.g., CRADA with the U.S. Army ERDC).

Product overview

Puraffinity offers a unified product portfolio centered on its proprietary Puratech® adsorbent media platform for PFAS removal from water. The core product is Puratech G400+, an advanced adsorbent material engineered with patented surface chemistry technology for selective PFAS capture. This media is deployed through Point of Entry (POE) and Point of Use (POU) solution modules that can be integrated into existing water treatment systems as customizable plug-in solutions. The technology targets both short-chain and long-chain PFAS compounds, delivering up to 7x the capacity of conventional ion exchange resins with significantly faster kinetics and longer operational lifespan. Applications span residential, commercial, industrial, municipal, and environmental services sectors.

Partnerships

Four partnerships are on record, tiered core and minor.

• Giotto Water S.r.l.coreChannel Partner/ Reseller/ Distributor · 10 March 2026Distribution agreement with Giotto Water S.r.l. (part of Giotto Group) to expand access to Puraffinity's PFAS treatment solutions for municipal and industrial customers across Italy. The partnership supports Italian customers responding to new PFAS requirements under the EU Drinking Water Directive. Combines Puraffinity's adsorption media with Giotto's project delivery, installation, and service support capabilities.
• U.S. Army Engineer Research and Development Center (ERDC)coreStrategic or Co-development Partner · 2 July 2025Cooperative Research and Development Agreement (CRADA) with U.S. Army ERDC to conduct laboratory and field trials comparing Puratech G400 with granular activated carbon and ion exchange resins for PFAS remediation. Research targets contamination from legacy facilities including AFFF. Develops performance data for potential DoD installation applications.
• Envytech Solutions ABcoreChannel Partner/ Reseller/ Distributor · 2 June 2025First commercial agreement for full-scale deployment of Puratech G400 in Nordic region.

Direct peers

• Cyclopure: US-based developer of PFAS-selective adsorbent media (DEXSORB) for water treatment. Closest direct peer: Puraffinity and Cyclopure both commercialize purpose-built PFAS capture media competing against GAC and ion exchange resins in municipal and environmental remediation markets.

Broad incumbents

• Calgon Carbon Corporation: Largest US producer of activated carbon for water treatment and the dominant incumbent supplier Puraffinity's Puratech G400+ is designed to displace. Comparable because utilities and remediation firms currently specify Calgon's GAC as the default PFAS treatment media.
• Purolite (Ecolab): Global manufacturer of ion exchange resins, including PFAS-selective resins (e.g., Purofine), competing head-to-head with Puraffinity's media in drinking water and groundwater remediation applications. Comparable as the primary ion-exchange incumbent benchmarked against Puratech.
• LANXESS: German specialty chemicals company whose Lewatit ion exchange resins are widely deployed for water treatment and PFAS removal. Comparable as a large, vertically integrated European specialty media incumbent with established municipal and industrial customer relationships.
• DuPont Water Solutions: Division of DuPont offering Filmtec reverse osmosis membranes and AmberLite ion exchange resins for water purification, including PFAS treatment. Comparable as a global incumbent selling PFAS-relevant separation media into the same municipal and industrial channels.
• Veolia Water Technologies: Global water treatment EPC and solutions provider offering PFAS treatment systems, often incorporating GAC and ion exchange. Comparable as a system integrator and end-to-end PFAS solution provider that competes for the same municipal and industrial tenders (and where Puraffinity's CEO previously led).
• Xylem: Global water technology company (now including Evoqua) providing treatment systems, filtration, and services for municipal and industrial water, including PFAS applications. Comparable as a broad incumbent system integrator that could embed competing media or own adsorption technologies.
• Jacobi Carbons: Major global supplier of activated carbons for water and air purification, with strong municipal water utility presence. Comparable as the kind of incumbent GAC supplier Puraffinity is displacing in municipal PFAS removal applications.

Emerging players

• ResinTech: US-based specialty manufacturer of ion exchange resins including PFAS-selective products (e.g., SIR-900), serving municipal and industrial water treatment. Comparable as a more focused, smaller-scale US challenger to Puraffinity in the PFAS-selective resin/media category.
• 374Water: US-listed company developing AirSCWO supercritical water oxidation systems for PFAS destruction. Comparable as an emerging PFAS treatment technology competitor whose destruction approach, if adopted, could divert spend away from adsorbent media like Puraffinity's.
