Our Capabilities
Puragen’s capabilities are built to deliver the best filtration solutions for every customer, in the most sustainable and cost-effective way.
Our award winning chemists, materials scientists and engineers use leading lab facilities and analytics to derive and support precise technical solutions for each customer requirement.
We supply a comprehensive range of carbons tailored to specific applications. We also enhance the performance of our carbon for specific processes via impregnation and precise particle sizing.
We operate a growing mobile filter fleet to deliver scalable, plug and play filters to customers, with maximum flexibility, minimal downtime, and no on-site waste handling.
We can manage as much of the carbon lifecycle as each customer requires, from supply, carbon exchange and reactivation to system maintenance and optimisation.
We operate one of the most advanced closed-loop carbon reactivation networks in Europe to deliver efficient filtration, traceability and environmental benefits.
Our processing and logistics hubs deliver to and support each customer’s needs across our full range of products and services.

Applications
Puragen’s Air & Gas applications remove VOCs, odors and hazardous pollutants for cleaner air & gas emissions, assured compliance and improved air quality.
Flue Gas & Stack Emissions
Remove harmful air pollutants for waste incineration in flue gas treatment (FGT) systems across the EfW (energy-from-waste) industrial & manufacturing and waste sectors.
VOCs & Odor Control
Capture and remove volatile organic compounds (VOCs) and industrial odors across municipal water, waste processing, chemical manufacturing, food & beverage, industrial & engineering and remediation sectors.
Puragen’s Water & Liquid applications remove PFAS, dissolve VOCs, chlorine/chloramine and organic contaminants to improve quality across water and liquid processes—for potable, process and waste water across commercial, residential and municipal sources and industrial applications.
Drinking Water
Remove and destroy PFAS, pesticides, pharmaceuticals, chlorine and VOCs for clean, safe water.
POU/POE
Point-of-use and point-of-entry carbons for homes and businesses, to improve the quality and taste of potable water.
Wastewater
Removes pharmaceuticals, industrial chemicals, micropollutants and dissolved VOCs.
Soil & Ground Water Remediation
Eliminate pollutants from contaminated sites and groundwater.
Beverage Production
Enhance clarity, taste, and safety in drinks. Dechlorinate mains water to enhance beer and beverage production.
Puragen’s Biogas product and services remove H₂S, siloxanes, VOCs and ammonia to upgrade raw biogas to high-quality biomethane that meets gas-to-grid injection standards and protects combined heat and power (CHP) engines.
Biogas & Biomethane Purification
Remove H₂S, siloxanes, VOCs and ammonia from raw biogas to meet grid injection standards.
Industries We Serve
Puragen offers tailored applications for a large number of evolving purification needs across multiple industries
Remove contaminants for safe drinking water and wastewater discharge.
Improve water quality of commercial and residential water via the use of POU and POE filters.
Clean up emissions at EfW facilities and purify biogas at AD sites and landfills to protect CHP engines and upgrade biomethane for G2G injection.
Capture emissions and odors from waste facilities such as waste reception halls and waste transfer stations.
Filter emissions from industrial and manufacturing processes.
Remove liquid and gas phase hazardous chemicals from soil and groundwater.
Enhance safety and quality through purification, decolorisation, deodorisation and removal of organic compounds.
Purify, decolorise and remove contaminants from chemical and medical products.

I have worked extensively with the Puragen team over many years and have always found them to be extremely knowledgeable, helpful and willing to go the extra mile to get projects completed on time and on budget. I would have no hesitation in recommending them for any activated carbon purification project.
