Abstract

U ovom radu opisani su dezinfekcijski procesi obrade voda pomoću klora, kloramina, ozona, klorovog dioksida i ultraljubičastog (UV) zračenja. Dezinfekcija voda provodi se u svrhu uklanjanja onečišćivala poput bioloških, mineralnih i organskih nečistoća, radioaktivnosti, induciranog zagađenja, te smanjenja koncentracija elemenata poput Fe, Mn i H2S koji premašuju dogovorenu granicu normi. Cilj dezinfekcije pitke vode i vode za kućnu upotrebu je uspostavljanje nacionalnih standarda koje je preporučila Svjetska zdravstvena organizacija (SZO). Prilikom dezinfekcije vode nastaju nusprodukti koji mogu biti štetni za zdravlje ljudi, te je iz tog razloga potrebno poboljšati metode dezinfekcije voda.

Abstract (english)

This paper describes the disinfection processes of water treatment using chlorine, chloramines, ozone, chlorine dioxide and ultraviolet (UV) radiation. Water disinfection is carried out for the purpose of removing pollutants such as biological, mineral and organic impurities, radioactivity, induced pollution and reducing the concentration of elements such as Fe, Mn and H2S that exceed the agreed upon norms. The goal for disinfecting drinking water and water for domestic use is to establish national standards recommended by the World Health Organization (WHO). By-products are created during the disinfection process and they can be harmful for people and so for that reason it is necessary to improve the methods of water disinfection.
