Activated carbon is mainly used for filling, dechlorination, oil removal, purification, and deep treatment of various industrial wastewater in equipment for producing urban drinking water, pure water, distilled water, and ultra-pure water.
Activated carbon is a porous carbon-containing material that has a highly developed pore structure and is an excellent adsorbent. The adsorption area per gram of activated carbon is equivalent to that of eight tennis courts. Its adsorption effect is achieved through physical adsorption and chemical adsorption.
In addition to carbon elements, its components also contain small amounts of hydrogen, nitrogen, oxygen, and ash, and its structure is formed by stacking of carbon into hexagonal structures.
Due to the irregular arrangement of hexagonal carbons, coal-based activated carbon filter material has a large volume of micropores and a high surface area. High-quality coal is used as raw material for coal-based activated carbon, which is developed through a series of processes such as carbonization, cooling, activation, and washing. Its appearance is generally black cylindrical activated carbon, amorphous coal particle activated carbon, also known as broken carbon.
Generally made of powdery raw materials and binders, it is kneaded and extruded into shape, and then carbonized and activated through a series of processes. Powdery activated carbon with binders can also be extruded into shape. It has a well-developed pore structure, good adsorption performance, high mechanical strength, and easy repeated regeneration, and is used for the purification of toxic gases, waste gas treatment, industrial and domestic water purification treatment, solvent recovery, etc.
In coal-based activated carbon filter material, lignite activated carbon has more transitional pores and larger average pore size than anthracite activated carbon, and can effectively remove large organic molecules in water.
Activated carbon has a highly efficient air purification function, which can create a comfortable and clean environment and protect human health. Activated carbon is an invisible air filter that combines physical adsorption and chemical decomposition to decompose harmful gases such as formaldehyde, ammonia, benzene, cigarette smoke, and cooking fumes, especially carcinogenic aromatic substances. Activated carbon has extremely strong adsorption capacity and is commonly used as an adsorbent, catalyst, or catalyst carrier. It can easily come into contact with harmful gases in the air and use its own pores to absorb the harmful gas molecules into the pores and blow out fresh and clean air. Therefore, activated carbon is an indispensable partner in the home.
