In many filtration applications, carbon is often the preferred media of choice to absorb certain impurities and one of the most powerful absorbents available. Carbon is highly effective due to the vast surface area contained within a small footprint. One pound of carbon contains a surface area of approximately 100 to 125 acres and can absorb an extremely wide range of chemicals. As effective as carbon is, activated carbon is even more effective. Activated carbon is carbon that has been electro- positively charged to create adsorption. Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process differs from absorption, where the fluid (absorbate) permeates or is dissolved and held within the filter media. When adsorption is in play, the water, or other fluid to be filtered, passes over the positively charged carbon surface. The negatively charged ions of the contaminants are attracted and held to the surface of the activated carbon particles and effectively removed. Good Ideas Flow Like.
