Activated Carbon Powders:
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 dimensions 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 different 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 adsorption, while those made from Coconut Shell charcoals have advantage of being hard and hence there is less abrasion.
