Uporaba reverzne osmoze za čiščenje odpadne vode v avtomobilski industriji : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoČrv, KatarinaReverzna osmoza je ena pomembnejših tehnologij čiščenja vode z membranami. V tem raziskovalnem delu je bila na pilotni napravi reverzne osmoze izvedena filtracija vode onesnažene s topilom Nikutex, ... ki je v uporabi v avtomobilski industriji in ga je potrebno pravilno odvajati na komunalno napravo, tako da dosega določene zahtevane parametre. Za filtracijo tega sta bili uporabljeni dve različni poliamidni tankoslojni kompozitni membrani. Obravnavane so bile vrednosti glavnih parametrov, ki kažejo na onesnaženost vode ter razlike med uporabljenima membranama. Vrednost kemijske potrebe po kisiku se je po filtraciji z membrano DOW FILMTECTM BW60-1812-78 s 33535 mg/l znižala na 11013 mg/l, z membrano SUEZ AG-1812-HR pa na 5722 mg/l. Skozi obratovanje je opažen padec fluksa permeata in permeabilnosti, prav tako pa se je tekom filtriranja zmanjševala prevodnost. Rezultati kažejo, da je možno s pomočjo reverzne osmoze v odpadni vodi bistveno zmanjšati kemijsko potrebo po kisiku. V nalogi je predstavljena uspešnost filtracije topila, vplivi na mašenje in možnosti za nadaljnjo obdelavo dotične onesnažene vode.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [K.
