Surface water contains organic matters from human activities, discharged industrial wastewater, and generated from microbial activities in water body. Persulfate is one of the strongest oxidants and could be used to oxidize organic matters. Fluorescence excitation emission matrices is one of the qualitative methods to identify organic matters properties, instead of chromatography and ultraviolet visible detection. The objective of this study was to identify dissolved organic matter in source and treated water by using peroxidation activated persulfate followed by coagulation. Sampel was analysed by using fluorescence excitation emission matrices (FEEMs) to assess its properties. The results showed that Activated persulfate has a good performance as pretreatment, in order to oxidize organic matters, further the coagulation is suitable treatment to combine with peroxidation activated persulfate. Those treatment resulted lower fluorescence intensity in all regions, including aromatic protein, fulvic acid-like, soluble microbial products, and humic acid-like.
