We produce the folowing types of Activated Carbon –

 

POWDERED ACTIVATED CARBON

Powdered varieties of Activated Carbon are used in liquid phase application  primarily

 for removal of undesired colour, smell and other impurities inmany types of industries

including basic drugs, fine chemicals, glucose, sugar, electroplating plasticizers and so on.

Quite often, powdered carbon is washed with acid and then, repeatedly with water & dried

to minimize  impurities like soluble ash-iron, heavy metals etc. Activated Carbon is

invariably used in a batch process at the penultimate stage of  manufacture of a product.

A pre-determined quantity of activated carbon is added to a solution and after stirring for

a certain contact time mostly at elevated temperature carbon is filtered out or settled to

get a sparkling colour free solutions from which product is recovered.  it is pertinent to

mention that use of powdered activated carbon apart from decolourising imparts several

other benefits like longer shelf life

, truer, and bolder crystals, closer melting and boiling points etc.

Granular Activated Carbon –

Granular activated carbons are mostly made from Coconut Shells on petroleum

 coke, bituminous coal or lignite. Granular activated carbon is used in continuous

process in areas like water treatment(drinking & effluent water), removal of mercury

from effluents or alkali cells, solvent recovery,  gold recovery, removal of odour,

 gas masks, as catalyst carrier, for decholorination of water, purification & separation

of gases, kitchen hoods, dry cleaning etc.
