Granular Coconut Shell Based Activated Carbon, Packaging Type: HDPE Bag

The use of activated carbon to remove harmful impurities like organic contaminants from water has been practiced since Roman times. Activated carbon is the generic term used to describe a family of carbonaceous adsorbents with a highly amorphous form and extensively developed internal pore structure. Activated carbon is extremely porous with a very large surface area, which makes it an effective adsorbent material. This large surface area relative to the size of the actual carbon particle makes it easy to remove large amounts of impurities in a relatively small enclosed space. Many natural substances are used as base materials to make activated carbon. The most common of these used in water purification are lignite, bituminous and anthracite coal and peat, wood and coconut shell. Different base materials and the activation process results in unique pore size and pore distribution. The pore size grouping in carbon is commonly described by its pore diameter. Macropores (above 50 nanometers [nm] in diameter); mesopores (two to 50 nm diameter) and micropores (under two nm diameter). Another way to think of and visualize pore structure is transport and adsorption pores: transport pores bring adsorables to the adsorption pores. Coconut Shell-Based Activated Carbons are the least dusty. Predominantly microporous, they are well-suited for organic chemical adsorption. Coconut Shell-Based Activated Carbons  has the highest hardness compared to other types of activated carbons, which makes it the ideal carbon for water purification. Coconut Shell-Based Activated Carbons  products are well known for their signature adsorptive properties. Very large internal surface areas characterized by microporosity along with relatively high hardness and low dust make these carbons particularly attractive for water and critical air applications.
