WHAT IS ACTIVATED CARBON?

Activated carbon is a highly porous material with a tremendous ability to attract and remove a wide range of organic compounds as well as some inorganic compounds. It begins life as organic matter with a high natural carbon concentration, such as coal, wood, peat, or coconut husk. The matter is slowly heated in a low-oxygen environment, drawing out water and impurities without burning. The resulting material, known as char, then undergoes a variety of physical and chemical processes to dramatically increase its surface area and create a submicroscopic network of pores.
 
Activated carbon works through the process of adsorption, attracting the targeted compounds along its vast surface area. The porous network ensures that the compounds are efficiently transported to the internal surface area for adsorption to occur.

TYPICAL APPLICATION

• Removal of volatile organic compounds such as Benzene, TCE, and PCE.

• Hydrogen Sulfide (HS) and removal of waste gases

• Impregnated activated carbon used as a bacteria inhibitor in drinking water filters

• Removal of taste and odor causing compounds such as MIB and geosmine

• Recovery of gold

• Removal of chlorine and chloramine

Designing a proper activated carbon filtration system with enough contact time, pressure drop, and vessel size is important. Also, activated carbon’s physical and chemical characteristics play an important role in removing contaminants effectively. Therefore, material testing is essential and ASTM test methods such as butane activity, surface area, density, and water content (moisture) can be carried out to find the best suitable material for your application.

TYPES OF ACTIVATED CARBONS

Different types of activated carbon 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 of activated carbon is application specific. Selecting the correct activated carbon product and mesh size depends on the application and contaminants you plan to remove.

COCONUT SHELL BASED ACTIVATED CARBONS

The very large internal surface areas characterized by microporosity along with high hardness and low dust make these coconut shell carbons particularly attractive for water and critical air applications as well as point-of-use water filters and respirators

• Very high surface area characterized by a large proportion of micropores

• High hardness with low dust generation

• Excellent purity, with most products exhibiting no more than 3-5% ash content.

• Renewable and green raw material.

WOOD-BASED ACTIVATED CARBONS

It produces different performance characteristics in industrial applications typically catered to with coal or coconut products.

Wood based activated carbon has a high surface area characterized by both mesopores and micropores and has excellent decolorizing properties owing to its signature porosimetry

• Relatively low density

• Renewable source of raw material

IMPREGNATED

ACTIVATED CARBON

Surface impregnation chemically modifies activated carbon through a fine distribution of chemicals and metal particles on the internal surfaces of its pores. This greatly enhances the carbon’s adsorptive capacity through a synergism between the chemicals and the carbon. And provides a cost-effective way to remove impurities from gas streams which would otherwise not be possible.

COAL-BASED ACTIVATED CARBONS

Demand is typically high for this relatively low cost filter media for both gas and liquid applications. Coal based activated carbon has a high surface area characterized by both mesopores and micropores.

• Consistent density

• Hard materials with minimal dust generation.

• Economical
