ACTIVATED CARBON FILTER

Activated carbon is a very well known technology that is designed to remove organics, taste and odor from water through adsorption process. There are varieties of carbon that are widely used in industries; including wood, lignite, coal, and coconut shell. Coconut shell is the most common and renewable sources for activated carbon.

Adsorption takes place due to intra-molecular attraction between the carbon surface and the substance. The force of the attraction can be altered by increasing the density of the carbon or by reducing the distance between the carbon surface and the substance (typically by reducing the median pore size). As the water flows through the carbon, the attractive force triggered and adsorbed the substance onto carbon’s surface. Organic compounds, volatile organic compounds, and halocarbons are the most highly attracted to the carbon surface.
