Economic evaluation of fluoride removal by membrane capacitive deionization

Today, one of the most important issues all is supply drinking and utility water, which basic need for human beings, to be healthy reliable, economical. Some substances in natural water sources pose a danger living creatures when they exceed certain concentrations. Fluoride, can commonly found as result or industrial effects, poses various risks not only its deficiency, but also excess. Therefore, fluoride concentration should under control. Membrane Capacitive Deionization Process an effective method remove ions from water. In this study, firstly, optimum conditions have been determined by working on removal groundwater with MCDI prepared synthetically. Subsequently, groundwater, was obtained Isparta province containing 7.71 mg/L fluoride, treated membrane capacitive deionization at 99%. Groundwater has reduced below limit. For treatment, 0.06 kWh/m3 energy expensed corresponds cost $ 0.006/m3. These results are quite economical compared other methods.
