Water purification
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
Our Powder activated carbon is manufactured using pure pine wood which is an excellent base for manufacturing activated carbons with good adsorption power. The steam activated process is done by activating the charcoal in a rotary kiln by heating at high temperatures by steam. The activated carbon that comes out from the kiln is called unwashed activated carbon. These unwashed activated carbon has higher ash and iron content. This is reduced by washing the unwashed activated carbon with acid (HCl / H2SO4) and purified water. This results in reduction of ash content to as low as 1% and iron as low as 50 ppm. The gradation of different qualities of activated carbon is done on the basis of Methylene blue value and iodine value. The iodine value is a better test as the particle size of iodine molecule is small enough to penetrate the smallest of pores. We can relate the iodine value of activated carbon directly to its surface area because of the above fact.

HiraChem is your specialist supplier of Granular Activated Carbon. 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.
One of the main applications of granular activated carbon is the purification of water. Its function is the retention of organic contaminants and the elimination, by chemical reaction, of the free residual chlorine that remains in the water after the disinfection stage. In order to inhibit bacterial growth, the surface of the carbon is impregnated with 0.1% metallic silver to make carbon bacteriostatic using ionic silver to enable it to bind strongly with carbon surface to make it suitable to function and purify large volumes of water. - High efficiency - Negligible silver leaching - No health hazards to humans - No loss in Bacteriostatic property up to 6000 litres water - Available in Granular and block form
CHM REMOVAL BLOCK (Heavy Metal Removal) - Heavy metal (HM) is any metallic chemical element are highly toxic for both animals and human beings, and can be bio-accumulated through biological chains and are non-biodegradable and persistent. Their toxicity may occur due to industrial emission that contaminates waterways, nearby streams and rivers, contamination of irrigation water, the application of fertilizer and metal-based pesticides, harvesting process, transportation, storage, or sale. Elements, such as Cadmium and Chromium, are considered carcinogenic, while Iron, Copper, Manganese, Zinc, and Nickel are considered essential trace elements. Arsenic is also another heavy metal which is available in almost 70% bore well water. Therefore, it is essential to purify the water to make it potable. The conventional methods for heavy metal removal from waste water which includes chemical precipitation, reverse osmosis, and solvent extraction are expensive. Adsorption on adsorbent such as active carbon or modified active carbon is an alternative method, because it is cost effective and simple to design. Size & Diameter can be customised as per buyer's requirement.
Among its numerous sources, coconut shells have gained significant attention as a sustainable and efficient raw material for producing high-quality activated carbon. Coconut shell-based steam-activated Carbon is mainly used for the removal of chlorine, organic contaminants, color and odor from drinking water to make it suitable for human consumption. Being microporous in internal structure, coconut shell activated carbon is well suited for organic chemical adsorption, including volatile organic chemicals. - One of the prominent applications of coconut shell-based activated carbon is in water treatment processes. It effectively removes impurities, organic contaminants, and heavy metals, ensuring clean and safe drinking water. - It acts as a decolorizing agent, removing impurities and unwanted odors from edible oils, beverages, and food products finding its application in the food and beverage industry. Additionally, it is employed in the purification of sugar syrups, ensuring high-quality and clear syrup for various confectionery and beverage manufacturing processes. - It serves as an excellent adsorbent in the production of drugs, where it eliminates unwanted impurities, colorants, and traces of heavy metals making it ideal choice in pharmaceutical industry too. The high purity and porosity of coconut shell-based activated carbon make it a preferred choice for pharmaceutical manufacturers to ensure product quality and safety.
