Dissolved Organic Matter (DOM) is found in surface and groundwater. In recent years, it has been observed that the load of Natural Organic Matter (NOM) in raw water sources has significantly increased. The presence of NOM in these sources negatively affects the drinking water treatment process. It not only causes problems related to color, taste, and odor but also increases the consumption of coagulants and disinfectants, which in turn results in higher sludge production and the formation of harmful compounds during disinfection.
Natural Organic Matter (NOM) can be removed using various treatment methods. The most basic and economical method among these is conventional treatment, which involves coagulation-flocculation followed by sedimentation and filtration through a sand filter.
