Removal of natural organic matter from water using advanced oxidation processes

U radu su istražene metode uklanjanja prirodne organske tvari iz vode za piće primjenom naprednih oksidacijskih procesa koji se zasnivaju na stvaranju jakog oksidacijskog sredstva - hidroksilnih radikala. Ispitana je primjena kombiniranih metoda ozoniranja, ozračivanja ultraljubičastim svjetlom (UV) i dodatak vodikovog peroksida. Učinkovitost razgradnje organske tvari određena je praćenjem koncentracije ukupnog organskog ugljika, UV-apsorpcije kod 254 nm, te smanjenjem koncentracije trihalometana nakon kloriranja.In this work Advanced Oxidation Processes, that are based on producing strong oxidant - hydroxyl radicals, were investigated for Natural Organic Matter removal during drinking water production. Applied processes are ozonation, ultraviolet irradiation, hydrogen peroxide addition, and combination of them. The efficiency of the organic matter removal was measured by total organic carbon concentration, UV 254 adsorption, and trihalometane formation potential reduction after chlorination
