Activated carbon is one of the world’s most effective adsorbent. Due to its vast surface area and pore structure it possesses a unique ability to adsorb high levels of chemicals, gaseous pollutants and toxins. This makes it an important agent in the processes of purification and environmental recovery.
Its high adsorption power and its ability to regenerate makes it one of the most effective and environmental friendly alternatives to reduce emissions in industrial vapor streams and purification of water.
Types of products
Different types of activated carbon products are suited for various specialized applications.
- Granulated activated carbon
- Pelletized activated carbon
- Powdered activated carbon
- Impregnated activated carbon
- Catalytic activated carbon
Each grade and size is application specific. Selecting the correct product and mesh size depends on the application and contaminants to be removed.
What is activated carbon?
Activated carbon is made from materials such as coal, wood and coconut shells. The materials are converted into specific products with varied properties. Each product has a variation of specialised applications. The activated carbon’s physical and chemical characteristics play an important role in removing contaminants effectively. Pore size, density and mesh size all affect the products adsorption power and application area. Coconut based activated carbon with its large internal surface area characterised by micro porosity and low dust makes it suitable for water purification and critical air applications. Wood based activated carbon with a large internal surface area characterised by both micro- and mesoporousity has excellent decolorizing characteristics.
Typical application areas
- Removal of volatile organic compounds such as Benzene, TCE, and PCE.
- Hydrogen Sulfide and removal of waste gases
- Purifying and removal of contaminants from industrial wastewater.
- Impregnated products used as a bacteria inhibitor in drinking water filters
- Removal of taste and odor causing compounds such as MIB and geosmine
- Recovery of precious metals.
- Vapor phase removal, VOC, of industrial contaminants.
