Abstract:The membrane bioreactor (MBR) system was investigated regarding its nitrate removal capacity from drinking water. The performance of a pilot-scale MBR was tested, depending on the operational parameters, using sucrose as a carbon source. Drinking water from the source was introduced into the reactor in order to study the influence of flow-rate on the nitrate removal and denitrification efficiency of drinking water. The content of the nitrate was around 70 mg/L and the C/N ratio was 3:1. Nitrate removal efficiencies above 90% were obtained by flow-rates lower than 4.8 L/h. The specific denitrification rates varied between 0.02 and 0.16 g/L NO3/ (g/L MLSS.d). The efficiencies and nitrate removal were noticeably affected by the flow-rate and hydraulic retention times. At the maximum flow-rate of 10.2 L/h still 68% of the nitrate had been removed, whilst the highest specific denitrification rate was achieved at 0.2738 g/L NO3/ (g/L) MLSS.d). The maximum reactor removal capacity was calculated at 8.75 g NO3/m3.h.

Title:Efikasnost membranskog bioreaktora za denitrifikaciju vode za piće
Abstract:U radu je ispitan kapacitet membranskog bioreactora (MBR) za uklanjanje nitrata iz pijaće vode. Testirane su mogućnosti poluindustrijskog postrojenja MBR u zavisnosti od ope- rativnih parametara koristeći saharozu kao izvor ugljenika. Pijaća voda iz izvora je dove- dena u reaktor da bi se analizirao uticaj protoka na efikasnost denitrifikacije i uklanjanja nitrata iz pijaće vode. Sadržaj nitrata je bio oko70 mg/l, a odnos C/N je bio 3:1. Efikasnost uklanjanja nitrata je oko 90% pri protoku manjem od 4,8 l/h. Specifična brzina denitrifikacije je bila u opsegu od 0,02 do 0,16 g/l NO3/(g/L MLSS d). Efikasnost uklanjanja nitrata je značajno zavisila od protoka i hidrauličkog vremena zadržavanja. Pri maksimalnom protoku od 10,2 L/h moguće je uklanjanje do 68% nitrata, dok je ostvarena najveća specifična brzina denitrifikacije od 0,2738 g/L NO3/(g/L) MLSS d). Izračunato je da je maksimalni kapacitet uklanjanja nitrata 8,75g NO3/m3 h.
