Abstract
U današnje vrijeme sve je veća količina otpadnih voda kao posljedica razvoja industrije i porasta populacije. Kako bi se takva voda vratila u okoliš na ekološki i ekonomski prihvatljiv način razvijaju se postupci pročišćavanja otpadnih voda. U nove tehnologije pročišćavanja spadaju i membranski procesi, koji dobivaju značajnu ulogu u zadnjih desetak godina. Cilj ovoga rada bio je ispitati utjecaj koncentracije aktivnog mulja (MLSS) na obradu komunalne otpadne vode (KOV-a) membranskim bioreaktorom (MBR-om) s ultrafiltracijskom (UF) membranom. MBR-om su kroz tri perioda ispitivani parametri: mutnoća, električna provodnost (κ), pH vrijednost, ukupan ugljik (TC), ukupan dušik (TN), kemijska potrošnja kisika (KPK), biokemijska potrošnja kisika kroz 5 dana (BPK5) i ukupna suspendirana tvar (TSS). Rezultati su dokazali da smanjenjem MLSS-a dolazi do najvećeg uklanjanja TC-a, KPK i BPK5. Za najmanju vrijednost MLSS-a od 6,95 g L^-1 smanjenje je 83,87 %, 98,95 % i 99,10 % za navedene parametre. Niže vrijednosti separacije uočeni su za κ i TN, dok na mutnoću MLSS nema značajan utjecaj.
Abstract (english)
Today, the amount of wastewater is increasing as a result of industrial development and population growth. In order to return such water to the environment in an environmentally and economically acceptable manner, wastewater treatment processes are being developed. New purification technologies include membrane processes, which have played a significant role in the last ten years. The aim of this study was to investigate the effect of sludge concentration on municipal wastewater (KOV) treatment by a membrane bioreactor (MBR) with an ultrafiltration (UF) membrane. MBR tested parameters for three periods: turbidity, electrical conductivity (κ), pH, total carbon (TC), total nitrogen (TN), chemical oxygen demand (COD), biochemical oxygen consumption over 5 days (BOD5). active sludge concentration (MLSS) and total suspended solids (TSS). They were monitored for how MLSS affects the quality of the perm. The results proved that the reduction of MLSS results in the highest removal of TC, COD and BOD5. For the smallest MLSS value of 6.95 g L^-1 the decrease is 83.87 %, 98.95 % and 99.10 % for the above parameters. Lower separation values were observed for κ and TN, while MLSS turbidity was not significantly affected.
