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 Odour 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 odours 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.

Frequently Asked Questions
Volatile organic compounds (VOCs) are gases released from industrial processes, chemicals, and materials. They can contribute to air pollution and may pose health risks with prolonged exposure. Controlling VOC emissions is essential for regulatory compliance and environmental protection.
Activated carbon removes VOCs and odors through adsorption, trapping molecules on its highly porous surface. This process is highly effective for capturing a wide range of organic compounds. It is commonly used in air filtration and purification systems.
Granular activated carbon is versatile and used in many air and water applications. Impregnated carbon is treated with chemicals to target specific contaminants more effectively. Extruded pellets offer low dust and high durability, making them ideal for continuous airflow systems.
Yes, VOC control solutions can often be integrated into existing systems such as filters, scrubbers, or air handling units. This allows facilities to improve performance without major infrastructure changes. Proper system design ensures optimal efficiency.
Industries such as manufacturing, waste management, food processing, and chemical production commonly require VOC control. Any operation that emits organic compounds or odors can benefit from treatment systems. Activated carbon provides a flexible and effective solution across these sectors.
