1.What is Activated Carbon?

_{Activated carbon, also known as activated charcoal, is a crude form of graphite, the substance used for pencil leads. It differs from graphite by having a random, imperfect structure which is highly porous over a broad range of pore sizes from visible cracks and crevices to molecular dimensions. The graphite structure gives the carbon its very large surface area which allows the carbon to adsorb a wide range of compounds.}

 

_{Activated carbon (activated charcoal) has the strongest physical adsorption forces, or the highest volume of adsorbing porosity, of any material known to mankind.}

 

_{Activated carbon (activated charcoal) can have a surface of greater than 1000m2/g. This means 3g of activated carbon can have the surface area of a football field.}

 

_{What is activated carbon made from ?}

 

_{Activated carbon (activated charcoal) can made from many substances containing a high carbon content such as coal, coconut shells and wood. The raw material has a very large influence on the characteristics and performance of the activated carbon (activated charcoal)}

2.Powder Activated Carbon (PAC) - pulverised carbon with a size predominantly less than 0.18mm. These are mainly used in liquid phase applications and for flue gas treatment.

Application

 Activated carbon

1.Air Treatment – Control of atmospheric release of potentially harmful or environmentally damaging substances.

2.Biogas Purification - Activated carbons and mobile carbon filters for the removal of H2S, siloxanes and other VOCs from biogas and biomethane streams.

3.Drinking Water Treatment – Purification of potable water for human consumption, at municipal treatment works or in home filters.

4.Effluent Water Treatment - Control of substances which are potentially environmentally damaging or harmful to water courses.

5.Food and Beverage – Essential processing stage in the production of a variety of food products, including sweeteners, glycerine and edible oil.and more application...
