EnviroSupply & Service's Premium 12x40 Coconut Shell Activated Carbon is a high activity granular activated carbon manufactured for high purity water production. Its large micropore volume makes it particularly well suited for the removal of low molecular weight organic compounds and their chlorinated by-products such as chloroform and other trihalomethanes (THMs). It is also ideally suited for the removal of oxidizing agents such as chlorine and ozone from water. An important feature of this material is its superior mechanical hardness and the extensive de-dusting during its manufacture ensures an exceptionally clean activated carbon product.
