Application of Coal-based Activated Carbon to Drinking Water Treatment

The characteristics of coal-based activated carbons which were produced with different coals and different production processes were elaborated.The application technology situation of activated carbon used in drinking water treatment was analyzed.The single application of powdered activated carbon and granular activated carbon as well as the combined application with other processes were introduced.Based on the application status of activated carbon,it was suggested that the activated carbon which used in water purification should be selected according to the raw water quality,process features and water production cost.
