Granular activated carbons are made from rigid raw materials, giving the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continous adsorption process and offer unusual economy in cases where carbon regeneration is favorable. In liquid phase applications they remove colloids and organic substances that give undesirable odors, colors and taste to the products. They are efficiently used for water dechlorination in processes which require super chlorination as well as the removal of organic substances from the water. In vapor phase application they participate in the solvent recovery, adsorption of colors, purification of carbon di-oxide and catalyst support. They are also used to reduce the COD and BOD in effluent waste water.
Granular activated carbon is produced from coconut shell charcoal by the process of steam activation. The coconut shell charcoal is fed into the rotary kiln and activated by steam at high temperatures resulting in the evaporation of impurities and opening up of pores on the surface. The resultant big particles are then crushed and sieved to get the desired particle size.
Our main grades of granular activated carbon are given as under. We can customize the iodine value as well as the particle size according to your requirements

Pure carbon which is gold recovery granular activated carbon is coconut-shell-based granular activated carbons specially designed for gold recovery operations. GR was developed to be a consistent, high performance, high activity gold recovery carbon product line. The activated carbon's ability to achieve high gold loadings and the relative ease with which they can be stripped enables gold processors to obtain the highest possible yields from ores with high silver/gold ratios, carbonaceous ores and ores containing other metals that complex with cyanide; for example, copper and nickel. In Carbon in Leach (CIL), Carbon in Pulp (CIP), and Carbon in Column (CIC) circuits, it is essential that the activated carbon employed provides excellent process performance, minimal losses due to attrition, and minimal maintenance problems.
Through the years, Pure carbon has continually upgraded its manufacturing processes to ensure that it continues to provide high quality products. Steps have been added to the manufacturing process which have improved the carbon's resistance to abrasion and reduced its tendency to plug retention screens in adsorption tanks. Platelets (flatter granules which are relatively long and wide while not particularly thick) can end up oriented in such a manner that they pass through the retention screens. This results in a loss of gold-containing carbon, which directly affects percent recovery and pro stability. In order to have a product that has less tendency to plug screens with "platelets," GR is also processed through a vee-wire screen and deÃ?Âdusted. GR products are manufactured specifically for gold adsorption. As a result, the quality of the carbon is extremely consistent and tailored to gold recovery applications. GR activated carbon enable the extraction of even trace amounts of gold from every ton of ore, even when processing average or low-grade ores. Pure Carbon expertise in activated carbon application technology is a valuable resource for designing and optimizing.

Usage - Quality granular/powder Activated Carbon from coconut shell suitable for water, air, food and beverage, pharmaceutical, mining and other various applications with the benefit of cost effectiveness, hardness, ease of handling and more importantly environment-friendly because it is from a renewable source.
Granular Activated Carbon (GAC) generally is an organic carbon filtration media of wood, coconut shells and coal. GAC used for water purification. GAC can remove certain chemicals, particularly organic contaminants from water as well as chemicals that produce odors or tastes to water such as hydrogen sulfide or chlorine. Other chemicals, specifically iron and nitrate, can not be removed with GAC. Also GAC should be changed based on contaminant levels and water use as higher levels or use may require more frequent change-outs.
Granular Activated Carbon Products range from the size 0.2mm to 4mm. Granular Activated Carbon has relatively larger particles size compared to powdered activated carbon and consequently, presents a smaller external surface.
Granular activated carbon is mainly made from coconut shell, apricot shell, and coal base, and is processed through a series production process. The appearance is black amorphous particles; it has developed pore structure, good adsorption performance, high mechanical strength, easily repeated regeneration, low cost, etc.
Activated carbon granules are widely used in drinking water, industrial water, waste gas treatment, food and beverage decolorization, gas purification, etc. Coconut shell granular activated carbon also has another special function, that is, gold mining.
