Water purification activated carbon is an amorphous carbon in the form of black powder, blocks, granules, or honeycomb structures, and also includes crystalline carbon with regular shapes. In addition to carbon, water purification activated carbon contains two additives: one is a chemically bonded element, primarily oxygen and hydrogen, which remain in the carbon due to incomplete carbonization or combine with the surface of the activated carbon through chemical bonds during the activation process; the other additive is ash, which is the inorganic part of the water purification activated carbon. The ash in the activated carbon can easily cause secondary pollution. Activated carbon is widely used in production and daily life due to its strong adsorption capacity.

The purified water activated carbon material is an amorphous carbon obtained through processing. It boasts a large specific surface area and excellent adsorption capabilities for inorganic or organic substances, as well as colloidal particles in gases and solutions. The purified water activated carbon material primarily includes activated carbon and activated carbon fibers. As an excellent adsorbent, the purified water activated carbon's properties are mainly determined by its unique adsorption surface structure and chemical properties. This material is chemically stable, has high mechanical strength, and is resistant to acids, bases, and heat, as well as being insoluble in water and organic solvents. It is recyclable and has been widely used in industries such as chemicals, environmental protection, food processing, and metallurgy. Currently, purified water activated carbon is extensively applied in wastewater treatment and air pollution control, demonstrating an increasingly promising prospect in environmental pollution management.

The primary raw material for activated carbon used in water purification can almost be any carbon-rich organic material, such as coal, wood, fruit shells, coconut shells, walnut shells, apricot shells, jujube shells, and more. These carbon-containing materials are converted intoActivated carbon is processed through an activation furnace, where it is pyrolyzed under high temperatures and certain pressures. During this activation process, a massive specific surface area and a complex pore structure gradually form, within and above which the so-called adsorption process takes place.

Activated carbon for water purification selectively adsorbs substances due to the fact that larger molecules with sizes smaller than the carbon's pores cannot penetrate. Water purification activated carbon is a hydrophobic adsorbent made from carbon-based materials, produced through high-temperature carbonization and activation. This type of activated carbon features an abundance of micropores and a vast surface area, effectively removing color and odor. It can eliminate most organic pollutants and certain inorganic substances from secondary effluent, including some toxic heavy metals.
