What are Extruded Activated Carbons?
Extruded Activated Carbons (EACs) are cylindrical activated carbon products designed for advanced adsorption applications. Produced by combining powdered activated carbon with binders and extruding it into uniform cylindrical shapes, EACs offer high mechanical strength, low dust generation, and optimised pore structure for diverse uses.
Why Choose Our Extruded Activated Carbon?
- High Strength and Durability: Engineered for use in fixed-bed systems and high-pressure applications.
- Low Dust Formation: Reduces handling issues and contamination risks.
- Optimised Adsorption: A balanced microporous and mesoporous structure for efficient removal of gases, vapours, and liquid impurities.
- Environmentally Friendly: Reusable and recyclable, contributing to sustainable industrial practices.
Applications
- Air Purification: Removes volatile organic compounds (VOCs), odours, and harmful gases.
- Water Treatment: Effective for potable water purification, industrial wastewater treatment, and pretreatment for desalination.
- Gas Treatment: Used in natural gas purification, solvent recovery, and mercury removal.
- Odour Control: Widely applied in municipal sewage treatment plants and industrial exhaust systems.
Packaging
Our Extruded Activated Carbons are available in:
- Bulk Bags: 500kg with bottom discharge spouts and lifting lugs.
- Smaller Bags: 25 kg woven polypropylene sacks, shrink-wrapped for easy handling and storage.
- Custom Packaging: Tailored solutions for export and project-specific requirements.

Projects
Sydney Desalination
Plant
In response to declining water levels, Sydney Water obtained approval for a Seawater Desalination Plant. Pilot testing favoured coarse dual-media filtration. We supplied C & S Brand Australian Filter Coal, on time and to exact specification.
Qurayyat Desalination
Plant
This plant is in operation to address water shortages in Muscat, Oman and surrounds. We supplied 2,210 cubic metres of C & S Brand Australian Filter Coal, delivered on time, to exact specifications.
Dungog WTP
This was the first contact filtration plant in Australia to use large effective size media, after pilot plant work by the Hunter Water Corporation. It was also the first to use C & S Brand Australian Filter Coal and remains an industry frontrunner with long-term results, durability and consistency.
Barangaroo Lendlease
Grand Casino
We supplied premium C&S Brand Australian Activated Carbon while transforming a former gas works site into a modern casino and hotel, effectively eliminating odours and volatile organic compounds (VOCs), and adding to Sydney’s evolving skyline.
Mt Crosby
Eastbank
This refurbishment project included converting 20 mono-media sand filters to dual-media filters with C&S Brand Australian Filter Coal. It extended filter run times, reduced backwashing frequency and improved plant performance, surpassing client expectations.

FAQs
What is extruded activated carbon used for in wastewater treatment?
Extruded activated carbon is commonly used in wastewater treatment for odour control and hydrogen sulphide (H₂S) removal from air emissions. Its cylindrical pellet shape offers low pressure drop, high mechanical strength, and efficient gas adsorption, ideal for:
Odour scrubbers at pump stations and wet wells
Air filtration systems at sewage treatment plants
Vapour phase filters treating exhaust gases
At James Cumming, we supply extruded activated carbon in 4 mm pellets, with impregnated options available for enhanced H₂S removal in municipal and industrial applications across Australia.
How long does extruded activated carbon last in H₂S removal systems?
The lifespan of extruded activated carbon in H₂S removal systems typically ranges from 6 to 24 months, depending on factors like:
– Hydrogen sulphide concentration
– Airflow rate and humidity
– Bed depth and residence time
Type of carbon (standard or chemically impregnated)
In municipal wastewater treatment plants, longevity is often improved using impregnated extruded carbon (e.g. KOH- or KI- treated), which reacts chemically with H₂S for greater removal efficiency.
At James Cumming, we offer technical support to help optimise carbon replacement cycles based on your specific odour control system and site conditions.
Is extruded activated carbon effective for municipal odour control?
Yes, extruded activated carbon is highly effective for municipal odour control, especially in treating hydrogen sulphide (H₂S) and other volatile organic compounds (VOCs) released from pump stations, sewer vents, wet wells, and wastewater treatment plants.
Its cylindrical pellet shape offers:
High surface area for gas adsorption
Low pressure drop in packed beds
Durability in high-flow and humid conditions
What’s the difference between KOH, KI, and CuO impregnated extruded activated carbon for H₂S removal?
The type of impregnate used on extruded activated carbon can determine how effectively it removes hydrogen sulphide (H₂S) under different conditions:
• KOH (Potassium Hydroxide): Reacts rapidly with H₂S to form potassium sulphide. It’s ideal for high H₂S concentrations and humid environments, such as wet wells, pump stations, and sewer vents. However, KOH-based carbons can degrade faster if fully saturated.
• KI (Potassium Iodide): Functions through an oxidation–reduction mechanism, converting H₂S into elemental sulphur. It’s best for moderate H₂S levels and is commonly used in municipal odour control systems requiring long media life and stable performance in variable humidity.
• CuO (Copper Oxide): Binds chemically with H₂S to form copper sulphide. This type is effective in drier gas streams or industrial air treatment systems, but is less suitable in high humidity environments like wastewater applications.
What are the benefits of using extruded carbon for H₂S scrubbing?
Extruded activated carbon offers several advantages for H₂S scrubbing in municipal and industrial air treatment systems:
High adsorption capacity for hydrogen sulphide and VOCs
Uniform cylindrical pellets ensure low pressure drop and consistent airflow
Mechanically strong, ideal for deep beds and high-flow systems
Available in impregnated grades (e.g. KOH, KI) for enhanced chemical reaction with H₂S
Longer service life in humid, corrosive environments typical of wastewater infrastructure
At James Cumming & Sons, we supply high-performance extruded carbon engineered for reliable H₂S removal in odour control units, biofilters, and ventilation systems across Australia.
