What is Granular Activated Carbon?

Granular Activated Carbon is created from organic raw materials that are high in carbon. Such materials include wood, coal, and lignite – a type of brown coal made from naturally compressed peat. Activated Carbon effectively absorbs pollutants and particulars because it is highly porous and provides a large surface area that allows it to continue to take in particles found in the water that can negatively affect your health. The U.S. Environmental Protection Agency recognizes activated carbon in the use of absorbing organic compounds, taste and odor compounds, and synthetic chemicals in the treatment of drinking water.
