Powdered Activated Carbon
Powdered activated carbon (PAC) is a fine black powder that is produced by heating carbon-rich materials, such as coal, wood, or coconut shells, in the absence of air to create activated carbon. PAC is widely used in various applications, including water treatment, air purification, gas processing, and industrial processes.
In water treatment, PAC is added to the water to remove organic contaminants, such as pesticides, solvents, and pharmaceuticals, as well as taste and odor-causing compounds. The PAC particles attract and adsorb these contaminants, effectively removing them from the water. PAC is also used in wastewater treatment to remove dissolved organic compounds and color from the wastewater.
In air purification, PAC is used to remove pollutants, such as volatile organic compounds (VOCs), from the air. The PAC particles adsorb these pollutants, effectively reducing their concentration in the air.
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.

Coal powder activated carbon with coal columnar activated carbon as the selection of high quality anthracite as raw materials, the use of advanced production equipment and process refined processing. The physical properties of coal powder activated carbon: Black amorphous granular or fine powder, no smell, no smell, no sand, not soluble in any solvent. Selective adsorption capacity of various gases, organic pigment and nitrogen base have high capacity of adsorption capacity. Coal powder activated carbon chemical characteristics: coal powder activated carbon not only carbon, but also contains a small amount of chemical combination, such as carbonyl, phenols, ethers, ether. On the surface of these oxides and complex, some derivatives from raw materials, some are activated, after cremation and by air or water vapour generated. In the activation process, some of the raw materials contained in the activation of activated carbon to become ash, ash is the main component of alkali metal and alkali metal salts, such as carbonate and phosphate, etc..

Powder Activated Carbon Introduction: Powder activated carbon is made of high quality wood chips, which has large adsorption capacity and fast filtering characteristics. Mainly used in all kinds of amino acid or water industry, refined sugar decolorization, monosodium glutamate industry, glucose industry, starch sugar industry, chemical fertilizer, dyes intermediates,and food additives.
Powdered activated carbons (PAC) are defined by the ASTM as particles passing through an 80-mesh sieve (0.177 mm) and smaller. By varying manufacturing conditions, internal pore structures are created by imparting unique adsorption properties specific to each product type. The choice of product for a specific application will vary due to differing impurities and proprietary process conditions. The adsorptive capacity of powdered activated carbon (PAC) makes it ideal for removing a variety of contaminants from water, air, liquids and gases.

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
