An Intro to Activated CarbonActivated carbon is a valuable weapon in the arsenal of water treatment technologies. It is widely used to remove contaminants from water. Activated carbon is an amazing substance which justifies a brief explanation. What is it? The primary raw material for activated carbon is any organic material with high carbon content such as wood, coconut shells and coal. Granulated activated carbon is produced by grinding the raw material, adding a suitable binder to give it hardness, re-compacting and crushing to the correct size. The carbon is activated by thermal decomposition in a furnace using a controlled atmosphere and heat. This process produces a product with an incredibly large surface area per unit volume. One quart of carbon provides a surface area equivalent to six football fields. | |
