Activated carbon filtration is one of the most commonly used techniques and plays a crucial role in the field of water treatment due to its effectiveness in removing various contaminants and impurities present, reducing odors and improving the quality of water. drinking water. Activated carbon, with exceptional adsorption properties, is capable of retaining a wide range of unwanted substances, making it a preferred choice for many filtration applications.

Grain activated carbon (GAC-WIA) is crushed and sieved to obtain particles of the order of 0.2 to 5 mm. The drinking water industry typically uses 8 x 30 mesh (0.80-1.0 mm effective size), or 12 x 40 mesh (0.5-0.7 mm effective size) . GAC is used in liquid phase and gas phase applications
