Technical and Economic Comparison of Conventional, Modify Conventional and Electrochemical Coagulation Processes

Öz

Electrochemical coagulation and modify conventional processes are alternative to the conventional coagulation method of water and wastewaters treatment. Although, there have been many reports on the technical suitability of electrochemical coagulation and conventional, no study has made a direct comparison of the economics of these processes and modify conventional process. This article demonstrated comparison of the economics of electrochemical coagulation; modify conventional and conventional processes of raw water treatment. Raw water samples were collected from selected villages in Katsina state, Nigeria. The samples were subjected to these treatment techniques. Ef cacies of these processes were determined individually and in combination. Operational and capital costs of these techniques were determined and compared for economics selection reasons. The study revealed that concerning the technical feasibility, no signi cant differences were found in the results achieved by the three technologies in the treatment of raw surface water, when the same values of pH, chlorine and aluminum concentrations were adopted in the reaction systems. Regarding the economic comparison, the electrochemical coagulation and modify conventional processes present lower operating costs for low and intermediate aluminum and chlorine doses. The highest operational costs were obtained with conventional coagulation with aluminum sulphate (alum, conventional water treatment process). It was concluded that conventional coagulation; modify conventional treatment and electrochemical coagulation techniques gave very similar ef ciencies in the removal of different types of pollutants; therefore an economic comparison is of major importance in order to recommend the use of one of these technologies.
