Color Removal of Pulp and Paper Mill Industry by a Hybrid Coagulation and Adsorption Process
Keywords:
Coagulation process, Adsorption process, Fenton processAbstract
The aims of this research is to study the color removal efficiency of a hybrid coagulation and adsorption process for treatment of effluent from pulp and paper mill industry and to compare the operation cost with the Fenton process. The results showed the hybrid process has color removal efficiencies in range of 85-90% (color of treated water < 50 ADMI) with the operation cost of 6.78 Baht/m3. Fenton process can remove color in the effluent from pulp and paper less than 50 ADMI with the operation cost of 15 Baht/m3(including the chemicals for pH adjustment). Therefore, the hybrid coagulation and adsorption process is the most suitable color removal process for pulp and paper mill industry in terms of color removal efficiency and operation cost.
