Granular Activated Carbon
High-porosity granular activated carbon made from 100% hazelnut shells, produced at any particle size in the 0–10 mm range. To read the figures, see iodine number.
Product
The standard media of fixed-bed filters.
Granular activated carbon (GAC) is the core adsorbent of fixed-bed filter systems. After carbonisation and activation, the natural cell structure of the hazelnut shell becomes a network of macro, meso and micro pores — contaminants are trapped deep inside this network.
In our indirectly heated stainless steel kiln the flame never touches the product; there is no brick lining, so no mineral contamination. Every batch is tested to ASTM standards in our own laboratory before shipping.

Applications
Where Is It Used?
Water Treatment
Removal of taste, odour, chlorine and organic contaminants from drinking and process water in fixed-bed filters.
Gas Treatment
Continuous adsorption of VOCs and odours in filter cartridges and granular packed beds.
Food & Oil
Removal of colour, odour and unwanted compounds from edible-oil and food processes in column systems.
Cosmetics
Reduction of colour, odour and impurities in cosmetic ingredients and process water.
Cat Litter

FAQ
About Granular Activated Carbon
What is granular activated carbon?
Granular activated carbon (GAC) consists of porous carbon particles 0.2–10 mm in size. It is used in fixed-bed filters, where contaminants are captured as water or gas flows through the granules.
Where is it used?
It is used in water treatment, gas treatment, food and oil processes, cosmetic-ingredient purification, odour and moisture control in cat litter, and sugar refining.
Which particle sizes are available?
Our crushing and sieving line produces the required size distribution within 0–10 mm, including standard ranges such as 0.5–2.5 mm, 1–3 mm and 2–4 mm.
For international buyers
Specify the right activated carbon for your process.
Akarbon manufactures activated carbon from hazelnut shells in Düzce, Turkey. Start with the AKARBON 800, 900 and 1000 technical data sheets, then discuss the form and particle size your process needs.
- Tell us the application, contaminants to remove and required treatment performance.
- Specify granular or powdered carbon, particle size and required test values.
- Include the requested quantity, delivery country and preferred schedule.
- List any required documentation, packaging or certification for confirmation with our team.
For fixed-bed filtration, review granular activated carbon (GAC). For dosing and subsequent separation, review powdered activated carbon (PAC). Final selection depends on your process conditions and testing.
