Abstract
Arsen, dobro poznat po svojoj toksičnosti, prisutan je u prirodnim vodama u mnogim područjima svijeta, pa tako i u podzemnim vodama istočne Hrvatske. Osim toksičnosti spojeva arsena, posebno arsenita, arsen stvara i veliki ekološki problem te je nužna obrada sirove vode prije distribucije. Također, karakteristika podzemnih voda istočne Hrvatske su i povećane koncentracije mangana, organskih tvari, željeza i amonijaka. Prisutnost mangana u vodi ne predstavlja veliki zdravstveni rizik za potrošača, no u velikim količinama negativno utječe na organoleptička svojstva vode. Najčešće primjenjivana metoda obrade vode je koagulacija i flokulacija, pri čemu dolazi do destabilizacije, aglomeriranja i taloženja čestica suspendiranih ili otopljenih tvari. Uspješnost koagulacije i flokulacije ovisi o vrsti koagulanta te njegovoj koncentraciji. U ovom radu ispitana je mogućnost uklanjanja arsena i mangana metodom koagulacije i flokulacije ovisno o vrsti uzorka sirove vode, temperaturi vode te koncentraciji doziranog koagulanta. Ispitivanje je provedeno uzorcima aerirane podzemne vode grada Osijeka, uzorcima vode rijeke Drave te njihovim mješavinama. Obrada vode provedena je uz predoksidaciju uzoraka s \(KmnO_{4}\) te doziranjem koagulanta \(FeCl_{3}\) i flokulanta polielektrolita Aquaflock 2530. Uz mjerenje početne i završne koncentracije arsena i mangana, učinak obrade određen je praćenjem vrijednosti i koncentracija suspendiranih tvari, boje, vodljivosti i ukupne tvrdoće.
Abstract (english)
Arsenic, well known for its toxicity, is present in natural waters in many parts of the world, including the groundwater of eastern Croatia. In addition to the toxicity of arsenic compounds, especially arsenite, arsenic also creates a major environmental problem and it is necessary to treat raw water before distribution. Also, the characteristics of groundwater in eastern Croatia are increased concentrations of manganese, organic matter, iron and ammonia. The presence of manganese in water does not pose a major health risk to the consumer, but in large quantities it has detrimental effect on the organoleptic properties of water. The most commonly used method of water treatment is coagulation and flocculation, which destabilizes, agglomerates and precipitates particles of suspended or dissolved substances. The success of coagulation and flocculation depends on the type of coagulant and its concentration. In this work, the possibility of arsenic and manganese removal by coagulation and flocculation method depending on the type of raw water sample, water temperature and concentration of dosed coagulant was investigated. The test was performed with samples of aerated groundwater of the city of Osijek, water samples of the Drava River and their mixtures. Water treatment was performed with pre-oxidation of samples with \(KmnO_{4}\) and dosing of \(FeCl_{3}\) coagulant and polyelectrolyte Aquaflock 2350 flocculant.
