چکیده
Organic matter present in natural water is a serious problem during treatment terms of the possibility creating disinfection by-products (DBP). The new materials and processes are still analyzed order to improve efficient removal organic as well other pollutants from intended for human consumption. aim presented study was evaluate efficiency using various combined processes: (a) coagulation adsorption, (b) oxidation with ozone coagulation, (c) ozone, (d) UV irradiation, adsorption modified surface water. In study, changes pH, turbidity, color, content (evaluated oxidizability, total dissolved carbon content, 254 272 absorbances), Ni2+, Cd2+, Pb2+ ions were determined purification. Supporting process by additional ozonation irradiation sample improved Processes associated increased removing color 4–16% reduced value UV254 UV272 absorbance 10–20%. Using did not significantly change matter. Heavy metal mostly removed (40–60%). Including resulted insignificant concentration purified (less than 5%). During tested, water, best observed after use enhanced oxidation. involvement have significant effect on pollutants.
