20.500.12556/DKUM-95074 Preliminary assessment of combination of membrane technologies for nutrient removals from domestic wastewater bachelor's thesis Predhodna ocena kombinacije membranskih tehnologij za odstranjevanje hranil iz gospodinjskih odpadnih voda The study focuses on wastewater treatment by investigating the use of microalgae in cooperation with bacteria, in combination with ultrafiltration and membrane photobioreactors. This approach also enables the extraction of nutrients retained by the organisms, referred to as biomass, which can subsequently be utilised. Three different water samples were tested and introduced into the same system. The first sample was the influent water, the second was the mixed liquor, in which microalgae function in a consortium with bacteria, and the third was the effluent water, referred to as permeate. Parameters such as pH, electrical conductivity, turbidity, suspended solids, chemical oxygen demand, inorganic and organic carbon, organic content, and ion concentration were analysed using standard procedures. Certain samples required filtration for specific analyses. The results indicated that measured values varied among the three samples, which is expected, as certain inorganic compounds are consumed as nutrients for microalgae growth. In addition, some nutrients are released through the progressive degradation of more complex compounds. This work demonstrates the effective application of these technologies and methods for municipal wastewater treatment, with a focus on the new rotating membrane (R-HFM), which has a positive impact on system performance. Overall, this represents a promising investment in the future of water treatment. Delo se osredotoča na čiščenje odpadnih voda z raziskovanjem uporabe mikroalg v sodelovanju z bakterijami, v kombinaciji z ultrafiltracijo in membranskimi fotobioreaktorji. Ta pristop omogoča tudi ekstrakcijo hranil, ki jih organizmi zadržujejo, poznanih kot biomasa, ki se jih lahko kasneje uporabi. Testirani so bili trije različni vzorci vode, ki so bili dovajani v isti sistem. Prvi vzorec je bila vhodna voda, drugi vzorec je bil mešani medij, v katerem mikroalge delujejo v konzorciju z bakterijami, tretji vzorec pa je bila izhodna voda, imenovana permeat. Parametri, kot so pH, električna prevodnost, motnost, suspendirane snovi, kemična poraba kisika, anorganski in organski ogljik, organska vsebnost ter koncentracija ionov, so bili analizirani po standardnih postopkih. Nekatere vzorce je bilo potrebno filtrirati za določene analize. Rezultati so pokazali, da se izmerjene vrednosti razlikujejo med tremi vzorci, kar je pričakovano, saj se nekateri anorganski spojini porabljajo kot hranila za rast mikroalg. Poleg tega se nekatera hranila sproščajo z naprednim razgradnjo bolj kompleksnih spojin. Delo dokazuje učinkovito uporabo teh tehnologij in metod za čiščenje komunalnih odpadnih voda, s poudarkom na novi vrteči membrani (R-HFM), ki pozitivno vpliva na delovanje sistema. Na splošno predstavlja to obetavno naložbo v prihodnost čiščenja vode.
