What are the primary functions of activated carbon in water purification?

Removal of organic contaminants: Adsorbs dissolved organics, pesticides, phenols, and industrial chemicals, reducing COD and improving water quality.、

Elimination of chlorine and chloramine: Catalytically removes free chlorine and chloramines, improving taste and odor while preventing disinfection by‑products (THMs, HAAs).

Adsorption of taste and odor compounds: Removes geosmin, MIB, and other earthy/musty odors from surface water.

Reduction of heavy metals: Modified carbons adsorb lead, mercury, cadmium, and chromium (VI) via ion exchange or complexation.

Removal of micropollutants: Captures pharmaceuticals, personal care products, endocrine disruptors, and microplastics in advanced treatment.

Improvement of color and clarity: Adsorbs colored organic molecules (tannins, dyes) for beverage, pharmaceutical, and industrial uses.

Support for biological filtration: In BAC systems, carbon hosts microbes that degrade organics while adsorbing non‑biodegradable compounds.
