| description | Chlorination is widely used as disinfection method in Malaysia which aim ensuring an acceptable and safe drinking water quality. However, studies conducted demonstrated that during chlorination process, the reaction between chlorine and natural organic matter in source waters may cause the formation of Trihalomethanes potential (THMFP).
In this study, factors influencing THM formation such as UV254, pH, and Dissolved organic carbon (DOC) was investigated. This experiment were conducted with two different water sources which are groundwater and surface water. The samples were taken from Borehole, USM and Jalan Baru WTP, Perak. Sodium hypochlorite were used as disinfectant. The water samples were chlorinated at different pH and contact time of 1 hr, 3 hrs, 6 hrs, and 24 hrs. After completed contact time, the range of TTHM concentration for groundwater and surface water were measured. The results of this study have shown that THM formation increases with increasing contact time. Besides that, THM formation rates ranged between 7.7 μg/L to 49.4 μg/L for groundwater while 13.8 μg/L to 40.3 μg/L for surface water. The highest concentration of TTHM were found at pH 7. |
