Abstract

Natural organic matter (NOM) refers to group of carbon-based compounds that are found in surface water and ground water. The aim of the study is to reveal organic matter characteristics in Jagir River as drinking water source and to characterize the organic components that could be removed by FeCl3 coagulation. Coagulation is the common water treatment process that can be used to remove NOM with FeCl3 coagulant in various dosage. NOM surrogates, including total organic carbon (TOC), ultra violet absorbance at 254 nm (UV254) and specific UV absorbance (SUVA) were chosen to assess the organic removal. Results of jartest experiments showed that NOM can be removed about 40% of NOM surrogates with 200 mg/L FeCl3. About 32% removal of dominated organic fractions humic substances from total fractions removal as detected by size exclusion chromatography (SEC)
