Residual chlorine is essential for water disinfection, but too much remaining after treatment can cause issues such as bad taste, odor, corrosion, and reduced biological activity. To safely and efficiently remove excess chlorine, industries, households, and municipal water plants commonly use coconut shell and nut shell activated carbon because of their strong catalytic properties, high surface area, and well‑developed microporous structure.

Activated carbon efficiently removes excessive nitrogen and phosphorus to combat eutrophication and ecological imbalance in modern water environments.

Activated carbon is the leading solution for removing persistent organic contaminants in water and air treatment. Its high porosity and adsorption capacity effectively eliminate pollutants like NOM, chemicals, and pesticides, improving water quality, taste, and odor across municipal and industrial processes.

Ammonia (NH₃) is a harmful, corrosive gas that requires efficient control, and impregnated activated carbon has emerged as the most effective and widely used solution for high‑performance NH₃ removal.
