Abstract:The membrane bioreactor (MBR) integrates well within the conventionally activated sludge system regarding advanced membrane separation for wastewater treatment. Over the last decade, a number of MBR systems have been constructed worldwide and this system is now accepted as a technology of choice for wastewater treatment especially for municipal wastewater. The aim of this work was to investigate and compare submerged MBR with conventionally-activated sludge system for the treatment of municipal wastewater in Maribor, Slovenia. It can be concluded from the results, that the efficiencies being determined by the parameters were satisfied, such as, chemical oxygen demand, total phosphorous, and total nitrogen, which were 97%,75%, and 90%, respectively. The efficiencies of ultrafiltration membrane for the same parameters were also determined, and compared with biological treatment. The results of this analysis show an additional effect regarding an improvement in the quality of the permeate but primary treatment is also very important. For successfully application of MBR system smaller grid for primary treatment is needed.

Abstract:Membranski bioreaktor (MBR) za obdelavo odpadnih voda združuje prednosti konvencionalnega čiščenja z aktivnim blatom in napredne membranske filtracije. Po vsem svetu v zadnjem desetletju število postavitev MBR sistemov izjemno narašča in s tem je ta nova tehnologija potrjena kot uspešna in učinkovita za obdelavo odpadnih vod, posebej komunalnih. Namen raziskave je bil razviti in primerjati učinek čiščenja MBR, ki ima vgrajeno potopljeno membrano, s konvencionalno čistilno napravo za obdelavo komunalnih odpadnih vod v Mariboru, Slovenija. Rezultati so pokazali, da je bilo čiščenje z MBR učinkovito, kar kažejo zadovoljive vrednosti parametrov kot so KPK, skupni fosfor in skupni dušik, katerih učinkovitosti znašajo 97 %, 75 % in 90 %. Za enake parametre smo raziskali učinkovitosti z uporabo UF membrane, ki smo jih primerjali z biološkim čiščenjem. Ugotovili smo, da membrana še dodatno prispeva k učinkovitosti, saj je kakovost permeata bila zelo visoka. Seveda pa je pomembno tudi primarno čiščenje, saj smo ugotovili, da za uspešno delovanje MBR sistema potrebujemo sita z manjšimi porami v primerjavi s konvencionalnim čiščenjem.
Keywords:komunalne odpadne vode, membranski bioreaktor, membranska filtracija, biološka obdelava
