WHAT IS ACTIVATED CARBON?

Activated carbon is considered the world’s most powerful absorbent. It is eco-friendly, due to its ability to regenerate

Coconut shell-based activated carbon

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.

Coal-based activated carbon

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

Wood based activated carbon

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

Catalytic based activated carbon

Catalytic carbon is a class of activated carbon used to remove chloramines and hydrogen sulfide from drinking water.

It has all the adsorptive characteristics of conventional activated carbons, as well as the ability to promote chemical reactions.

Catalytic carbon is not impregnated with caustic chemicals

Because catalytic carbons have no impregnates, you won’t have to worry about reduced organic odor capacity or the higher bed fire potential of the impregnated carbons.

Catalytic carbon is created by altering the surface structure of activated carbon. It is modified by gas processing at high temperatures to change the electronic structure and create the highest level of catalytic activity on carbon for reducing chloramine and H2S in water. This added catalytic functionality is much greater than that found in traditional activated carbons. Catalytic carbon is an economical solution to treat H2S levels as high as 20 to 30 ppm. Catalytic carbon converts adsorbed H2S into sulfuric acid and sulfurous acid which are water soluble, so carbon systems can be regenerated with water washing to restore H2S capacity for less frequent physical change-outs.

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.

Water treatment

Because of its antimicrobial/antiseptic properties, silver-impregnated carbon is an effective adsorbent for purification in earth-bound domestic and other water systems.

Gas purification

Impregnated activated carbon is used to treat flue gases in coal-fired generation plants and other air pollution control applications. Carbon can be specifically impregnated for removal of acid gases, ammonia and amines, aldehydes, radio-active iodine, mercury and inorganic gases such as arsine and phosphine. Carbon impregnated with metal-oxide targets inorganic gases including HCN, H2S, phosphine and arsine.
