Powdered Activated Carbon for Water Treatment
Powdered activated carbon (PAC) is a highly efficient adsorbent widely used in water treatment processes, valued for its excellent ability to remove organic pollutants, odors, colors, and micro-pollutants from water. Made from natural materials such as wood, coal, or coconut shells through carbonization and activation, PAC features a large specific surface area and abundant porous structure, enabling it to quickly adsorb harmful substances in water.
In water treatment, PAC is usually added directly to raw water or intermediate treatment processes. It can effectively remove refractory organic compounds, trihalomethane precursors, and residual pesticides that are difficult to eliminate by conventional filtration methods. Its fast adsorption speed makes it suitable for emergency water treatment, such as sudden water pollution incidents, to quickly improve water quality.
Compared with granular activated carbon, PAC has the advantages of low cost, flexible dosage, and easy operation, making it widely applied in drinking water purification, industrial wastewater treatment, and sewage advanced treatment. It plays a crucial role in ensuring water safety and protecting ecological environment.
