VOCs & Odor Control
Puragen develops and supplies activated carbons that enhance air quality and improve workplace conditions by removing harmful pollutants. We can help with compliance with regulatory standards such as the Clean Air Strategy, the Industrial Emissions Directive, and the U.S. Environmental Protection Agency National Ambient Air Quality Standards.
Contaminants we remove
Puragen supplies activated-carbon-based filtration services that remove volatile organic compounds (VOCs) and various odour-causing molecules:
Activated carbon products for VOCs and Odor Control
Puragen supplies a range of different activated carbon media for air treatment applications.
Granular Activated Carbon (GAC)
For applications where standard VOCs are the main contaminant group. Traditionally, 4mm pellets were used for this application, but recently large GAC from various raw materials has gained popularity.
We also offer virgin and reactivated versions. Reactivated carbon offers improved economic and environmental performance, with a far lower CO₂ footprint (>90%) compared with virgin materials.
Impregnated activated carbons
For the removal of odorous compounds that aren’t readily adsorbed by standard carbon grades, we offer specialised impregnated grades. We treat this media with a functional chemical to promote a reaction with the targeted compound.
These carbons are widely used for the abatement of inorganics such as H2S and NH3, as well as DMS and formaldehyde. This works as a chemisorption reaction, or a chemical process, rather than the physical process in standard adsorption. We also offer impregnated grades for abatement of heavy metals, notably mercury.
Extruded pellets
For the abatement of odors and the removal of VOCs, extruded activated pellets are typically used. We use impregnated versions for inorganic contaminants like hydrogen sulfide and ammonia to enhance efficiency. We also offer large GAC grades for this application.
Mobile filters for VOCs & Odor Control
Puragen supplies a wide range of mobile carbon filters for gas phase purification applications. These modular units are generally supplied on a rental and service basis and offer a convenient plug & play solution that requires no on-site carbon handling.
