DESICCA CHEMICALS Granular Activated Carbon grade DCG is a microporous form of Carbon manufactured from Coconut Shell Charcoal which is specially suited for the removal of taste, odour, chloride (free), ozone and dissolved organic contaminants. Activation is achieved with steam and it develops myriad of pores with enormous internal surface area.
Due to the superior hardness, DCG grade is specially suitable for high pressure and large volume D. M. Plant filters.
ACTIVATED CARBON GRANULAR
Activated Carbon Granulars
Size : 4 – 8 mesh
Range: 8-16,4-8,16-30 mesh etc.
The porosity creates a remarkable power of ADSORBTION.
In GAS PHASE adsorption, Granular Carbon is almost always used because the pressure drop in the carbon bed is of prime importance and only Granular Carbon will allow sufficient flow with an acceptable pressure drop.
In LIQUID PHASE applications, both Granular or powdered carbon can be used.
Due to SUPERIOR ADSORPTION, HIGH DENSITY, LOW ATTRITION LOSS, use of Granules has resulted in increased service life, greater filter efficiency, fewer regeneration cycles and economy on Hardware costs. Activated Carbon Granules made from coconut shell charcoal is used when a single product or grade is being continuously produced in large quantities.
Activated Carbon Granular is non Toxic, non Hazardous to the human being and non flammable and freely handled by human being
