Abstract: One of the several significant concerns related to water treatment plants is the transformation of natural organic matter (NOM) concerning quality and quantity due to the changing climatic conditions. The NOM consists of heterogeneous functionalized groups. Phenolic and carboxyl groups are the dominant groups that are pH-dependent and show a stronger affinity towards the metals. Properties of natural organic matter and trace elements govern the binding kinetics, influencing cations' binding to functionalized groups at lower pH. The water treatment process mechanisms like adsorption, coagulation, membrane filtration, and ion exchange efficiencies are sturdily influenced by the presence of NOM with cations and by the natural organic matter alone. The complexation among the natural organic matter and coagulants enhances the removal of NOM from the coagulation processes. The current review illustrates detailed interactions between natural organic matter and the potential impacts of cations on NOM in the water and wastewater treatment facilities.

Source water polluted by algae, ammonium and organic matter has been studied for many years. Sudden pollution incidents of source water have been reported across the whole country. Seasonal variability of rainfall across China has resulted in floods or droughts, thus incurred the high concentration of algae, ammonium and organic matter, causing severe challenges to the conventional water purification facilities. However, the conventional water treatment process is often unavailable to keep the safety of source water for drinking when sudden pollution occurs. Meanwhile, byproducts are often to be found over the whole treatment process, it is high time that researchers took effective measures to deal with this problem. In the present work, an overview of the recent research dealing with source water suddenly polluted by algae, ammonium and organic matter is presented.
