Abstract

In this study, the fate of THMs -formation .in seawater distillation process and the rates of THMs formation in the chlorinated blended distillate were examined under various experimental conditions. The following general equation was obtained empirically: Log (THM) = _A * Log (Cl2) + B * Log (TOC) + C (THM) is the concentration of total THMs in µg/l, (Cl2) and (TOC) are the concentration of chlorine doese and total organic carbon in mg/l, A,B, and C are estimated parameters. The results showed that THMs level increases with the increase of both chlorine and initial humic substances concentrations. Increase in temperature and contact time also increased THMs concentrations. On the other hand, pre-chlorination and aeration step of the seawater resulted in a reduction of THMs concentrations in the blended distillate.
