WELL INTERNATIONAL | TAMILNADU | INDIA | https://wellinternational.in Limitations of Activated Carbon While activated carbon is an excellent tool for drinking water treatment, it does have limitations. It may not effectively remove certain contaminants, such as dissolved inorganic substances like salts, minerals, and nitrates. Additionally, some contaminants, like pesticides, can be challenging to remove completely if their concentration in the water is high. Combination with Other Treatment Methods Activated carbon is often used in combination with other water treatment processes, such as coagulation, flocculation, sedimentation, and filtration, to achieve optimal water purification results. This combination approach ensures a comprehensive removal of various contaminants, providing safe and high-quality drinking water.
