Clean and safe drinking water is essential for human health. However, due to increasing industrial activities, agricultural runoff, and aging water supply systems, drinking water is easily affected by organic compounds, chlorine, pesticides, and other contaminants. Therefore, purifying drinking water is crucial.
This article will introduce the role of activated carbon in drinking water purification and help you choose the right type of activated carbon.
The Role of Activated Carbon in Drinking Water Purification
Activated carbon is a highly efficient adsorbent that can remove a wide range of impurities from water. With its extremely high surface area and well-developed pore structure, activated carbon effectively adsorbs dissolved organic compounds, residual chlorine, and other trace contaminants that are difficult to remove through conventional filtration methods.
The main contaminants that can be removed by activated carbon include:
- Chlorine and Chloramines: Eliminates unpleasant tastes and odors.
- Volatile Organic Compounds (VOCs): Such as benzene and toluene.
- Pesticides and Herbicides
- Disinfection Byproducts (DBPs): Byproducts formed during chlorination.
- Micropollutants: Such as pharmaceutical residues and endocrine-disrupting chemicals.
In addition, activated carbon improves the color, taste, and overall quality of drinking water, making it an ideal material for both industrial and household water purification systems.

The high efficiency of activated carbon in drinking water treatment is due to its unique adsorption mechanisms. Below is a brief overview of how activated carbon functions in water treatment:
Adsorption Mechanism
Activated carbon removes contaminants through two primary mechanisms: physical adsorption and chemical adsorption.
- Physical Adsorption: The porous structure of activated carbon captures contaminant molecules from water. Its micropores are particularly effective at adsorbing small molecules, such as VOCs and chlorine.
- Chemical Adsorption: Activated sites on the carbon surface react with certain contaminants to remove substances such as heavy metals and some organic compounds.
Role of Pore Structure
The pore size of activated carbon (micropores, mesopores, and macropores) determines its adsorption capacity for different types of contaminants:
- Micropores: Ideal for adsorbing small molecules, such as dissolved organic compounds and odor-causing substances.
- Mesopores: Suitable for medium-sized molecules, including natural organic matter and certain industrial pollutants.
- Macropores: Capture larger molecules, such as dyes and suspended particles.
Specific Processes for Removing Contaminants
- Improving Taste and Odor: Activated carbon adsorbs chemicals that cause unpleasant tastes and odors, such as chlorine and sulfides.
- Removing Harmful Chemicals: Effectively eliminates pesticides, herbicides, solvents, and industrial chemicals from water.
- Reducing Disinfection Byproducts (DBPs): Minimizes byproducts like trihalomethanes (THMs) formed during chlorine disinfection.
