20.500.12556/DKUM-79102 Izzivi in potenciali uporabe procesa osmoze pri obdelavi tekstilnih odpadnih voda magistrsko delo Challenges and potentials of using the osmosis process in treatment of textile waste water Tekstilne industrije po vsem svetu letno proizvedejo ogromne količine odpadnih voda. Te pa zaradi svoje onesnaženosti predstavljajo velik okoljski problem. Proces osmoze pa zaradi ekonomičnosti in učinkovitosti v zadnjih letih kaže velik potencial pri obdelavi odpadnih voda. V magistrski nalogi so predstavljeni rezultati obdelave sintetičnih tekstilnih odpadnih voda s procesom osmoze. Tekstilne vode so bile pripravljene po recepturi iz industrijskega tekstilnega obrata v tovarni Galeb d.d. v Omišu, na Hrvaškem. Pri procesu osmoze smo uporabljali biomimetične membrane z vstavljenimi molekulami proteina akvaporina. Zanimalo nas je, kako na proces vpliva spreminjanje različnih parametrov filtracije. Spreminjali smo pH vhodne raztopine, pretok črpalke, koncentracijo barvila, koncentracijo in vrsto gonilne raztopine, volumen raztopin in smer toka. Rezultati kažejo, da je proces osmoze učinkovit pri obdelavi tekstilnih odpadnih voda. Na proces bistveno vpliva izbor primerne gonilne sile, zagotoviti pa je potrebno dovolj visoko razliko v osmotskih tlakih med vhodno in gonilno raztopino. Textile factories around the world annually produce huge amounts of wastewater. These, however, pose a major environmental problem due to their pollution. Forward osmosis process, because of economy and high efficiency in recent years show great potential in wastewater treatment. The master's thesis presents the results of synthetic textile wastewater treatment with forward osmosis process. Textile water was prepared according to recipes from an industrial textile plant in the Galeb d.d. factory, in Omiš, Croatia. In osmosis process, we used biomimetic membranes with inserted protein molecules, aquaporin. We investigated how forward osmosis process is affected by changing different parameters. We changed pH of the feed solutions, the flow of the pump, the concentration of the dye, the concentration of draw solution, the volume of the solutions and the direction of flow. The results show that forward osmosis process is effective in textile wastewater treatment. The process is significantly influenced by the choice of a suitable driving force, it is also necessary to ensure a sufficiently high difference in osmotic pressures between the feed and draw solution. proces osmoze tekstilna odpadna voda reaktivna barvila biomimetične membrane forward osmosis process textile wastewater reactive dyes biomimetic membrane true true false [R.
