An activated carbon filter is a device used to extract or remove all harmful natural organic matter, chlorine, odors, and colors from water. The activated carbon method has two uses: as a filter and as a pre-filter.
As a filtration method, it removes chlorine from water and absorbs organic compounds so that it can be discharged and reused for other industrial purposes. In addition, as a pre-filtration, it is used with more complex systems, such as reverse osmosis water filtration systems.
Activated carbon filter manufacturers offer a variety of filter types to meet both domestic and industrial filtration needs. The capacity and performance characteristics of activated carbon depend on the standard and number of layers of the product.
Activated carbon works through an adsorption process, where contaminants in the water are adsorbed onto the surface of the carbon particles and retained on the surface. In water purification systems, activated carbon is effective in removing a variety of impurities, including organic compounds, chlorine, volatile organic compounds (VOCs), and disinfection byproducts.
When water passes through an activated carbon filter, the contaminants in the water come into contact with the porous surface of the carbon particles. Activated carbon with pores provides a larger adsorption surface area, allowing it to capture and retain contaminants through physical and chemical interactions.
The effectiveness of activated carbon filtration depends on several factors, including pore size distribution, surface area, and contact time between water and carbon. Microporous activated carbon has small pores and is particularly suitable for adsorbing small molecules and organic compounds. In addition, the longer the contact time, the more thorough the adsorption of pollutants and the higher the filtration efficiency.
