20.500.12556/DKUM-60144 The efficiency of a membrane bioreactor in drinking water denitrification Efikasnost membranskog bioreaktora za denitrifikaciju vode za piće 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. 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. capacity denitrification drinking water efficiency membrane bioreactor sucrose zmogljivost denitrifikacija pitna voda učinkovitost membranski bioreaktor saharoza true false true Angleški jezik Srbski jezik Znanstveno delo 2016-06-09 03:14:47 2017-07-19 11:32:11 2022-06-22 03:06:04 2019-07-11 11:36:48 2015 0 0 str. 269-275 št. 2 Letn. 21 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1451-9372 66.091 9527830 18019350 10.2298/CICEQ131129026P 1451-9372 URN:SI:UM:DK:S2UXTVPW Chemical_Industry_and_Chemical_Engineering_Quarterly_2015_Petrovic,_Simonic_The_efficiency_of_a_membrane_bioreactor_in_drinking_water_de.pdf Chemical_Industry_and_Chemical_Engineering_Quarterly_2015_Petrovic,_Simonic_The_efficiency_of_a_membrane_bioreactor_in_drinking_water_de.pdf 1 E31D42202038D3EADC5164B3485F630F 4647bde5827fdfe67eabf7d77e4bb6ab45b315709e0e1c4c3ab0a5f08163675c 6ea9b9ed-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=114368 http://www.doiserbia.nb.rs/Article.aspx?ID=1451-93721400026P 1 https://dk.um.si/Dokument.php?lang=slv&id=93959 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
