Activated carbon or activated charcoal is one of the most widely used substances in the water treatment industry, which is mostly produced in powder and granular forms. The main applications of activated carbon are separating the pigments, odors, tastes and chlorine from the water in the food and chemical industry, aquarium, domestic and industrial water treatment and in cleansing the skin and teeth. Activated carbon or charcoal is a type of crystalline absorbent material, which is made of charcoal and contains numerous pores in its structure. Activated carbon refers to a group of porous carbon materials which have a porous structure, high adsorption capacity, high surface reactivation capability and low cost compared to inorganic adsorbents such as Zeolite due to its remarkable interior surface area. In this regard, it is a very unique material. Their important applications are in the separation of odors, pigments, and unpleasant tastes from water in the domestic and industrial operations, solvent recycling, and air purification, especially in restaurants, food and chemical industries. Powdered activated carbon is less than 1 mm in size and has an average diameter between 0.15 ...
