Activated Carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. It is usually derived from charcoal of different sources; in our case, coconut shell.
With a surface area of over 1,000 m2/g, activated carbon is one of the most effective adsorption materials known. It works through a process called adsorption, where contaminant molecules are attracted to and held on the surface of the carbon.
Coconut shell based activated carbon is considered superior because of:
Irregular shaped particles sized 0.2mm to 5mm. Used in columns and beds for water and air treatment.
Fine particles less than 0.18mm. Used in batch processes, food & beverage, and pharmaceutical applications.
Cylindrical pellets extruded from powder. Used in gas phase applications with low pressure drop requirements.
