Sažetak
Natural organic matter (NOM) is a complex mixture of organic compounds, mostly fulvic and humic acids, hydrocarbons, proteins and amino acids derived from plant and/or microbial residues. The occurrence of elevated concentration of natural organic matter in water that has been used as source of drinking water, can negatively affect final organoleptic and chemical quality of treated water, especially when chlorine is used as disinfectant, since NOM serve as reactants in the formation of potentially harmful disinfection by -products (DBPs) such as trihalomethanes (THMs), haloacetic acids (HAAs), bromate , chlorate etc. Removal of NOM from water and thus the prevention of DBPs formation can be achieved using following water treatment processes: coagulation/filtration method, ion exchange, adsorption onto activated carbons and membrane filtration while an alternative and most environmentally accepted method for NOM removal represent the application of advanced oxidation processes (AOPs). AOPs imply formation of highly reactive hydroxyl radicals and its reactions caused by usage of ozone, hydrogen peroxide and/or UV light, as well as Fenton’s reagent and TiO2 catalysis. This study reports the latest achievements in NOM removal from water using the AOPs.
