activated carbon
What is Activated Carbon
Activated Carbon is a porous material that removes organic compounds from liquids and gases by a process known as “adsorption.” In adsorption, organic molecules contained in a liquid or gas are attracted and bound to the surface of the pores of the activated carbon as the liquid or gas is passed through.
Adsorption is different from Absorption. The pollutant or adsorbate sticks to the surface of the Activated Carbon.
Intermolecular attractions in the smallest pore of the carbon particle result in adsorption forces that cause precipitation of adsorbates from solutions, and condensation of adsorbate gases.
How does Activated Carbon work?
Due to its large surface area and specific surface chemistry, Activated Carbon can adsorb large quantities of pollutants from water and air. The compounds are adsorbed into inner pores within the Activated Carbon particle. It works better with particles that are less soluble in water: adsorbing them effectively.

●ITG with its group of companies is able to manufacture these based on specific industry requirements. Customized solutions are available based on client market needs.
Water Treatment
The coconut shell activated carbon used to treat industrial sewage generally requires an iodine value between 850 and 1000 mg/g. Specifications mentioned below are of our standard products and are not to be considered as the only purchase specification. Any other different combination of particle size and activity level can be manufactured as per the customer to meet precise customer needs.

Types of use cases in Water Treatment
● Compounds that cause unwanted taste, odour, or colour.
● Organic materials from decaying plants and other naturally occurring contaminants.
● Disinfection by-products (DBPs) linked to chlorine and alternative disinfectants.
● Algal toxins and cyanotoxins, such as microcystin-LR, cylindrospermopsin and anatoxin-A
● Endocrine-disrupting compounds that can adversely affect hormonal systems.
● Pharmaceutical and personal care products (PPCPs) contamination.

Different types of Activated Carbon used for different water treatment.
● GRANULATED ACTIVATED CARBON dechlorinates water, adsorbs organic material and produces a chemical-reducing environment.
● GRANULATED ACTIVATED CARBON IMPREGNATED with silver salts inhibits the growth of bacteria.
● PELLETIZED (OR EXTRUDED) ACTIVATED CARBON effectively dechlorinates and removes chemicals.
● POWDERED ACTIVATED CARBON is used to eliminate trace synthetic chemicals and taste and odour causing chemicals, and for chemical spills or algal blooms

- Recover solvents for reuse in industrial applications.
Different use cases for Air and Gas Treatment
Claring the Air
Activated carbon is the safest, most efficient technology for the removal of VOCs, airborne chemicals, gaseous pollutants, and other fumes and odours in industrial, municipal, or commercial applications. Activated carbon systems also have smaller footprints compared to other odour control technologies and are a cost-effective solution to meeting environmental regulations. Carbon systems are ideally suited for intermittent flow / loading applications

Gold Recovery/Mining
The critical test for activated carbon is how well it keeps its properties after months of use and reuse. By using the most durable coconut feedstock, to withstand the rigorous carbonization and activation process, we can consistently manufacture quality activated carbon for gold extraction. We manufacture products that are used extensively in Carbon in Column (CIC), Carbon in Pulp (CIP) and Carbon in Leach (CIL) applications. It is essential that these precious metals are recovered in the safest ways. Our activated carbon is made from high-quality coconut shells of exceptional carbonaceous hardness.
