Optimized techniques for design of cost-effective treatment of water pollutants by activated carbon

The main procedures and techniques for the adsorption process design of activated carbon are introduced, and the method of developing cost-effective treatment of water pollutants with activated carbon is described in this paper. Based on the process design parameters obtained by the adsorption capacity experiment and continuous flow breakthrough experiment, the adsorptive capacity indicator method for carbon selection and the micro-column rapid breakthrough method were used for a case study of a biological activated carbon system. It is demonstrated that establishing the biological activated carbon capability in the adsorption tower, utilizing the catalytic property of activated carbon, and reusing the reactivated spent carbon can further reduce the cost for treatment of water pollutants by activated carbon.
