Sažetak

Industrialization, population growth, and urbanization are the main causes for the generation of increasing quantities of municipal wastewater (MWW) which, untreated, pose a serious threat to natural aquifers. In order to protect the environment and natural resources, it is necessary to use high-efficiency and environmentally friendly technologies for the treatment of MWW. The goal of this work was treatment of MWW with advanced membrane processes; membrane bioreactor (MBR) and nanofiltration (NF) and reverse osmosis (RO). Laboratory and pilot treatment of MWW with MBR resulted in a reduction of more than 92 % in chemical oxygen demand (COD), biochemical oxygen demand (BOD₅), turbidity and suspended matter. The number of microbiological parameters decreased by 4.12 log₁₀ to 4.88 log₁₀. Subsequent treatment of MBR effluent with RO/NF membranes (XLE and NF270) further reduced all measured parameters.
