ACTIVE CARBON

 

   

 

 

Activated Carbon is a Microporous material manufactured from carbonaceous raw material i.e. Wood, Coconut Shell, Rice Husk, etc. The activation process develops a myraid of pores of molecular dimensious within the carbon which together constitutes an enormous internal surface area. The carbon atoms at the internal surface of Activated Carbon exert an alfraction on the molecules of the surrounding gases and liquids. The Strength of this force is related to the molecular structure of the surrounding medium. This is the mechanism by which Activated Carbon can be used to remove different components from a mixture.

Activated carbons are used as purifying and decolouring agents in a wide range of process and they absorb between
10% to 90% of their own weight of impurities from aquereous solution. Activated Carbon is added to the process liquor in an agitated vessel and filtered off after the required contact time.

 

Activated Carbon are of Two Type

POWDERED ACTIVATED CARBON & GRANULAR ACTIVATED CARBON

Different type of Powdered Activated carbon are available for use in different industries depending upon their industrial requirement as to METHYLENE BLUE adsorption, ASH Contents, IRON contents, CHLORIDE Contents, ACID Solubles etc. Granular Activated Carbon is used for Effluent and Water Treatment and fifferent grades are identified by its lodine Value.

RAW Material :

Silicon’s Activated Carbon is made from Charcoals of Pine Wood, Eucalyptus Wood and Coconut Shell depending upon the requirement of the user. Pine wood and Eucalyptus wood based charcoals are soft and have a high degree of Porosity and therefore give better activation. I.e. More Methylene Blue adsorbtion, while those made from Coconut Shell charcoals have advantage of being hard and hence there is less abrasion.

Applications

Granular Activated Carbon is produced from anycarbonaceous material like Eucalyptus, Saw dust, Rice Husk, Coal, Wood, Lignite and Coconut Shell but our Granular Activated Carbon is manufactured only from Coconut Shell only, it is hard compared with other carbon and has a higher surface area. It gives more adsorption capacity due to its microporous structure and superior hardness.

Application of Granular Activated Carbon

•   Effluent Treatment Plant
•   Waste Water Treatment for Reduction in the level of BOD & COD.
•   Catalyst in Chemical-Metallurgical Industries & Petroleum Industry.

•   Swimming Pools & Soft Drinks Plant for Dechlorination.
•   Purification of Drinking Water & Industrial Gases. l Solvent & Gold Recovery.
•   Absorption of Dissolved Organic Matter.
•   Water and Gas Mask Filter. l Breweries and Distilleries
