Abstract
Podzemne vode su najznačajniji izvori vode za piće na području istočne Hrvatske. Osnovne karakteristike podzemne vode navedenog područja su visoka tvrdoća vode, povišene koncentracije željeza, mangana, amonijaka, arsena te organskih spojeva što negativno utječe na estetske i zdravstvene aspekte vode za piće. U ovom istraživanju ispitan je utjecaj pH-vrijednosti (5; 5,5; 6; 6,5; 7; 7,5; 8 i 8,5) na učinak tri željezova koagulanta (FeCl3, Fe(NO3)3, i FeSO4) postupcima koagulacije i flokulacije. Željezo je dodano do ukupne koncentracije od 4 mg/L, a miješanje se provelo u dvije faze. Prva faza miješanja provedena je u vremenu od 2 minute i 200 okr/min, a potom u drugoj fazi uzorci su miješani još 10 minuta uz 30 okr/min. Potom su uzorci profiltrirani. U polaznim i profiltriranim uzorcima provedene su analize određivanjem vrijednosti sljedećih parametara: UV254, koncentracija željeza, alkalitet, ukupna tvrdoća, elektrovodljivost i pH-vrijednost. Rezultati provedenih istraživanja ukazuju da su koagulanti FeCl3 i Fe(NO3)3 dali zadovoljavajuće rezultate, dok se koagulant FeSO4 pokazao nešto manje uspješnim posebice pri uklanjanju željeza.
Abstract (english)
Groundwater is the most important source of drinking water in the eastern Croatian. The basic characteristics of groundwater in this area are high water hardness, elevated concentrations of iron, manganese, ammonium, arsenic, and organic compounds that affect drinking water and treatment processes of drinking water. In this research effect of pH (5, 5.5, 6, 6.5, 7, 7.5, 8 and 8.5) on three coagulant type (FeCl3, Fe(NO3)3 and FeSO4) by coagulation and flocculation processes was investigated. Coagulants were dosed at iron concentration of 4 mg/L and the samples were stirred in two steps. After 2 minutes mixing at 200 rpm, samples were mixed 10 minutes at 30 rpm. After conducted analyses, coagulants FeCl3 and Fe(NO3)3 showed satisfying results, while FeSO4 proved to be less effective, especially in iron removal.
