454 grams of activated carbons contain a surface area of almost 100 acres 40 hectares!
Carbon filtering is a method that uses a bed of activated carbon also known as activated charcoal (a form of carbon that has been processed to maximize the number of pores in them) to remove contaminant and impurities using chemical adsorption (substantial sharing of electrons between the surface of adsorbent and adsorbate to create a covalent or ionic bond). In other words, when activated carbon is used to treat water, the pollutant molecules are trapped inside these pores. |
