Activated carbon, also known as activated charcoal, is a highly porous material made from carbon-rich sources such as coconut shells, wood, or coal. It is primarily used for its ability to adsorb impurities and contaminants from liquids and gases. In water purification, activated carbon removes chemicals, toxins, and odors, making it a preferred choice for various applications. Among its types, Honeycomb Carbon and Coconut Carbon are particularly valued for their specific properties and filtration efficiency.
