Innovative Solutions

Our leadership in activated carbon is enabling breakthroughs across a broad range of global markets. Our innovation efforts are having a substantial impact for our customers. Our products are used in a wide variety of applications globally and subject to international chemical control and use-specific requirements.

Granular Activated Carbon

The activated carbon is milled and sieved to achieve particles in the range of 0.2 to 5 mm. Typically the drinking water industry uses an 8 x 30 mesh (effective size of 0.80-1.0 mm), or a 12 x 40 mesh (effective size of 0.5 - 0.7 mm). GAC is used in both liquid and gas phase applications.

Powdered Activated Carbon

Powdered activated carbon is milled and sieved and has a smaller particle size than GAC. The PAC particles are mainly less than 0.18 mm (80 mesh) usually with a median diameter of 15 to 30 microns. PACs are generally used in liquid phase applications and for flue gas treatment.

Extruded Activated Carbon

The activated carbon has been extruded into cylindrical shaped pellets with diameters ranging from 0.9 to 9 mm. These are mainly used for gas phase applications because of their low pressure drop, high mechanical strength and low dust content.

Product Specification

Activated Carbon is a porous material that removes organic compounds from liquids and gasses 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. The primary raw materials used in activated carbons is Anthracite Coal which is crushed, sized and processed in low-temperature bakers followed by high-temperature furnaces. This heating process is known as “activation,” and develops the pore structure of the carbon. Through adjustments in the activation process, pores of the required size for a particular purification application are developed.

Consistent Density
Hard Materials
Minimal Dust Generation
Impregnated Carbon

The impregnation optimizes the existing properties of the activated carbon giving a synergism between the chemicals and the carbon.

Activated Anthracite Coal

The filter material has certain adsorption capacity after elementary activated treatment.

Demercuration Carbon

This high efficient carbon with powder size aims to reduce the content of hydrargyrum vapor discharged from fire coal power plant and fire furnace.

Silver Impregnated Carbon

This series carbon can be applied for purification, bactericide and sterilization which can be eliminate the impurities of water.

Anthracite Filter Material

Anthracite promotes higher service flow rates , longer filter runs and produces consistent improvements in turbidity removal.

Solvent Recovery Carbon

This type of carbon mainly applied for recovery and separation of organic solvent and its vapors. (Ether, Ketone, Alcohol, Chloroform, Fluoroform, Aromatic, Tetrahydrofuran, Carbon Disulfide.)
