An ISO 9001:2008 Certified Company


We at GCARBON, manufacture wide range of GAC to suit different applications.

We manufacture over twenty grades of activated carbon. These are thermally activated using rotary kilns under carefully controlled conditions. The resulting pore structure is excellent for liquid phase applications; especially where removal of color, taste, odorous or other moderate to large molecules.

We manufacture activated carbon primarily from coconut shell charcoal and also manufacture special impregnated grades of carbon for effluent treatment compressed gas and air purification, for ore extraction, for gas mask, etc.

Our Bacteriostatic Activated Carbon (BAC) with silver impregnation finds use in POU apparatus like in portable drinking water purification.

All our products confirms to AWWA standards and our products are tested to relevant ASTM standards.

GS Series Of GAC

GS Series Granular Activated Carbon (GAC) is premium grade Granular Activated Carbon exclusively from Coconut shell charcoal with size range of 4 to 40 Mesh. The pore structure is carefully controlled to facilitate the adsorption of both high and low molecular organic molecules. GS series are intended to use in de-chlorination of water, reducing organic impurities (COD removal) and as pre-treatment for reverse osmosis and ion exchange system. The product is also used in waste water treatment.

GS series are manufactured by high temperature steam activation using state of art Rotary Kilns with closely controlled process parameter. With our exceptional cost to performance value GCARBON will be your right choice.

Optimum Mesh Size

The 8 x 30 mesh carbon have proven to have approximately 10 percentage greater surface area than 4 x 8 mesh carbons and is more highly activated due to smaller granule size. 8 x 30 mesh carbon is the right choice for applications that requires chloramine and residual ozone removal.

Ideal pore structure

The well defined pore structure and high surface area maximizes the removal of color bodies and dissolves organics that causes undesirable taste, odor and foam. The carbon finds use in the bottled water, beverage and brewery industry.

Superior Physical Stability

GS Series granular Activated Carbon high surface area coupled with exceptional high hardens and attrition number thereby enhancing life of usage. They have very low dust.

Excellent Chlorine and Organic Removal Capacity

GS Series GAC has excellent chlorine and chloramines removal capacity. They remove residual ozone. Their organic removal properties are well established in waste water management.

GS Series granular activated carbons are produced from selected grades of coconut shell charcoal. They are manufactured by high temperature steam activation under carefully controlled conditions. They are exceptionally hard, dust free product with high surface area with pore size distribution to offer adsorption of both high molecular and low molecular weight compound.

They are low water and acid soluble. Because of their high hardness, this media will not be susceptible to fines or dust generation, especially important after a few rigorous backwashes. This product is excellent adsorbing media for many odoring and coloring molecules (TOC'S and DOC'S).

Packing Details

Standard Packing will be in 25 Kg/ 40 Kg HDPE Sacks. Special packing in 12.5Kg is also available.

500 Kg/ 1000Kg Super sacks are also available on request.

Wet activated carbon depletes Oxygen from air and therefore dangerously low level of oxygen may be encountered. Whenever workers enter vessel in confined space containing activated carbon, Oxygen levels should be monitored and necessary reaction for low oxygen area should be followed
