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 based activated carbon originates from coal that has undergone a steam activation process Coal based carbon has mainly mesopores and macropores and is very popular in gas phase purification portable water purification wastewater purification and aquariumpond water purification applications The carbonaceous product of wood Applications Gas phase purification Water purification system
Coconut shell activated carbon is derived from coconut shells. It has a very high hardness and is more abrasion resistant than any other type. It is a totally natural, environmentally friendly product that has a very small carbon foot print. The carbonaceous product of coconut. Applications â?? Portable water purification Wastewater purification Gold absorption from gold solution Medical use
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
We are supplier and exporter of Activated Carbon. Granular Activated Carbon Products range from the size 0.2mm to 3.75mm. Granular Activated Carbon has relatively larger particles size compared to powdered activated carbon and consequently, presents a smaller external surface. Powdered Activated Carbon Powdered Activated Carbons are small activated carbon particles, with a size that is predominantly less than 0.075 mm. Activated Carbon is used worldwide in purification of Water, Air, etc. We are producers Dura specie of Palm Kernel Shells Powder & Pellets Activated Carbon, with over 1600 Iodine level and equally high level of Harness.
We are exporter of Activated Carbon. Activated carbon made from raw organic material such as coconut shell. The raw material of activated carbon pulverized and sieved into appropriate and uniform particle sizes. Carbon has been used as an adsorbent for centuries. Activated carbon is a particularly good adsorbent due to its high surface area to volume ratio.
