Abstract
Komunalne otpadne vode su neizbježan rezultat modernog života, te njihovo pročišćavanje spada u vrlo važne zadatke. Cilj obrade vode je uklanjanje neželjenih elemenata iz vode ili smanjivanje njihove koncentracije kako bi bila primjenjiva za upotrebu ili za ispuštanje u prirodne vodonosnika. U te svrhe se koristila ultrafiltracija (UF) kao jedan od tlačnih membranskih separacijskih procesa. Primarni cilj ovog rada bio je uklanjanje mikrobioloških parametara te tako ispitati učinkovitost UF membrana prilikom obrade komunalne otpadne vode. Ultrafiltracija je provedena sa sedam membrana: GH, GK, PT, PU, PW, MW i ZW-1. Praćene fizikalno-kemijske karakteristike bile su mutnoća, pH, vodljivost, kemijska potrošnja kisika (KPK), biokemijska potrošnja kisika (BPK5) i ukupni dušik (TN). Osim praćenja navedenih karakteristika komunalna otpadna voda je bila podvrgnuta i mikrobiološkoj analizi. Mikrobiološka analiza podrazumijevala je određivanje sljedećih mikrobioloških parametara: ukupne koliformne bakterije, Escherichiu coli, Pseudomonas sp, ukupan broj bakterija na 37°C i 22°C, fekalnih koliformna te fekalnih streptokoka. Postupkom ultrafiltracije obrade komunalne otpadne vode zadovoljeni su zakonski uvjeti čime se potvrđuje učinkovitost UF membrana.
Abstract (english)
Municipal wastewater is an inevitable result of modern life, and its treatment is a very important task. The purpose of water treatment is to remove unwanted elements from the water or reduce their concentration to make it usable or to discharge it to natural aquifers. For this purpose, ultrafiltration (UF) was used as one of the membrane separation pressure processes. The primary objective of this paper was to remove microbiological parameters and thus to test the efficiency of UF membranes in the treatment of municipal wastewater. Ultrafiltration was performed with seven membranes: GH, GK, PT, PU, PW, MW and ZW-1. The physicochemical characteristics monitored were turbidity, pH, conductivity, chemical oxygen demand (COD), biochemical oxygen demand (BOD5) and total nitrogen (TN). In addition to monitoring these characteristics, municipal wastewater was also subjected to microbiological analysis. Microbiological analysis included the determination of the following microbiological parameters: total coliform bacteria, Escherichiu coli, Pseudomonas sp, total bacterial count at 37 °C and 22 °C, fecal coliforms and fecal streptococci. Ultrafiltration of municipal wastewater treatment fulfills the legal requirements, which confirms the efficiency of UF membranes.
