Abstract

Zaradi večanja svetovne populacije in razvoja se potrebe po pitni vodi povečujejo. Ker so viri sladke vode omejeni ali že močno izkoriščeni, je po nekod potrebno zagotoviti pitno vodo iz drugih virov. Razsoljevanje nudi dobro alternativo klasičnim virom pitne vode, vendar ima vsaka tehnologija svoje vplive na okolje. Največjo obremenitev za okolje pogosto predstavlja odpadna slanica, saj vsebuje visoke koncentracije soli, v kateri so sledi drugih kemikalij, ki se uporabljajo pri razsoljevanju. V diplomskem delu so povzete raziskave o vplivih na okolje, ki so jih tuji raziskovalci izvedli na napravah, ki obratujejo že več let. Predstavljene so glavne kemične spojine, prisotne v odpadni slanici, in njihov vpliv na okolje. V drugi polovici naloge so prikazani načini izračuna razredčenja slanice v morju. Na podlagi analize podatkov iz oceanografske boje Vida sem za izračun začetnega razredčenja v različnih pogojih za teoretični izpust slanice v tržaškem zalivu uporabil statični mode. Izračuni so izdelani za tri možne iztoke iz manjše razsoljevalne naprave v različne okoljske pogoje in za različne dimenzije šobe.

Secondary title:	Environmental impact of brine discharge from desalination plant
Secondary abstract:	Population growth demands constant increase in drinkable water production. Many developing countries have a shortage of fresh water so they have to tap into alternative water sources. Desalination technologies provide the possibility to produce fresh water from sea or brackish water. Every technological process has its by-products; the major one in desalination is the rejected brine. This thesis presents some research made on the influence of brine discharge on the marine environments and the brine chemical characteristics from the desalination plants in the Mediterranean region. The second half of the thesis is dedicated to brine discharge modelling and calculation of near zone dilution. Analysing data received from the oceanographic buoy Vida, the near zone dilution for a small desalination plant in the gulf of Trieste is being calculated. Calculations are made for three different output flows with different output diffusers with the average and critical temperatures and salt concentration of the sea environment.
