Abstract	Prisutstvo arsena, mangana i željeza u vodi za piće je nepoželjno te je njihovo uklanjanje iz vode za piće nužno. Ponekad se ta tri elementa nalaze zajedno u sirovoj vodi te postoje metode za njihovo zajedničko uklanjanje. U ovom radu provedeno je nekoliko metoda uklanjanja arsena, mangana i željeza: katalitička oksidacija i taloženje na masi Greensand uz prethodnu aktivaciju mase 0,1 M otopinom HCl-a, katalitička oksidacija i taloženje na masi Greensand uz prethodnu ozonzaciju vode i adsorpciju na masi Bayoxide. Provedeno je i uklanjanje peterovalentnog arsena flokulacijom i membranskom filtracijom kroz uronjivu membranu. Kao flokulant koristila se sol FeCl3 i njena optimalna koncentracija za 100% uklanjanje arsena iznosila je 16,5 mg L-1, a eksperimentalno je određena Jar testerom. Arsen je potpuno uklonjen adsorpcijom na masi Bayoxide, membranskom filtracijom uklanjanje je bilo u rangu zakonskih propisa, dok ostalim metodama nije postignuto zadovoljavajuće uklanjanje. Koncentracija mangana je uklonjenja ispod maksimalno dopuštene koncentracije metodom katalitičke oksidacije uz prethodnu ozonizaciju. Uklanjanje željeza svim provedenim metodama bilo je uspješno.
Abstract (english)	The presence of arsenic, manganese and iron in drinking water is extremely undesirable, and their removal from drinking water is necessary. Sometimes these three elements come together in the raw water so there are methods for their joint removal. This work has carried out several methods for arsenic, manganese and iron removal such as: catalytic oxidation and precipitation on Greensand with Greensand activation with 0.1 M HCl, a catalytic oxidation and precipitation on Greensand with pre-oxidation with ozone and by filtration over granular adsorbent Bayoxide. Pentavalent arsenic was removed by coagulation/ microfiltration technology using immerse membrane. FeCl3 was used as flocculant. Optimal dosage of FeCl3 for 100% arsenic removal was 16.5 mg L-1 which was determined on Jar tester. As (V) has been completely removed on Bayoxide by adsorption and by membrane filtration removal was in range which is determined by rule book, while other methods did not achieved satisfactory removal. Manganese concentration was below the maximum contaminant concentration during catalytic oxidation and precipitation on Greensand with pre-oxidation with ozone. Iron removal was successfull with all methods which were performed.
