| Sources and levels of trihalomethanes in Suez bay water: Attaka power station (case study) | ||
| Abstract | ||
| Trihalomethanes have been identified as one of the most important disinfection byproducts resulted from using hypochlorite in power stations. So, Attaka power station was chosen as a case study which used hypochlorite as biological fouling control in its cooling seawater system. Water samples were collected monthly during 2016-2017 from four sits in the inlet, outlet, after dosing hypocrite and at mixing point. The seawater samples were analyzed for water temperature, pH value, salinity, oxidizible organic matter, total residual chlorine and trihalomethanes (THM’s). The results showed that the two main forms of THMs formed in the receiving seawater were broomcorn and dibromochloromethan. The broomcorn compound was fluctuated between 12.16ppm and 237.25ppm with a mean value of 77.23 ppm and with a total annual of 926.76ppm, while dibromochloromethan ranged from 0.28 to 4.20ppm. Significant positive correlation was found between trihalmethnes fractions and both of the measured concentrations of the total residual chlorine and organic matter, while negative correlations with water temperatures and pH values were noticed. No correlation between trihalomethanes and salinity was recorded. | ||
