Activated carbon filtration is a process that uses activated carbon to remove impurities and contaminants from air and water. The carbon is treated to create a large surface area, allowing it to adsorb various substances, including chemicals, odors, and pollutants. This makes it effective for applications such as drinking water purification and air quality improvement. The filtration process works by passing air or water through a bed of activated carbon. As the contaminants come into contact with the carbon, they adhere to its surface, effectively trapping them. This method is widely used in water treatment plants, air purifiers, and industrial processes to enhance safety and quality.
