Powdered Activated Carbon Powdered activated carbon (PAC) is a fine black powder that is produced by heating carbon-rich materials, such as coal, wood, or coconut shells, in the absence of air to create activated carbon. PAC is widely used in various applications, including water treatment, air purification, gas processing, and industrial processes. In water treatment, PAC is added to the water to remove organic contaminants, such as pesticides, solvents, and pharmaceuticals, as well as taste and odor-causing compounds. The PAC particles attract and adsorb these contaminants, effectively removing them from the water. PAC is also used in wastewater treatment to remove dissolved organic compounds and color from the wastewater. In air purification, PAC is used to remove pollutants, such as volatile organic compounds (VOCs), from the air. The PAC particles adsorb these pollutants, effectively reducing their concentration in the air.
