Studies on economic property of pretreatment process of brackish water using electrocoagulation (EC) method

Abstract In this paper the further research results of improving economic property of EC method was discussed. In order to reduce the cost and raise the handling efficienty, five different technological processes have been set up and studied. The best one was the using iron electrode and aerating for raw water combine with reusing flocs. It can reduce 60% of handling cost in comparison with aluminium electrode and remove 75% of hardness.
