Sažetak:
The main landfill of the city of Zagreb generates several hundreds cubic meters of heavily contaminated leachate per day. The organic composition of the leachate is particularly peculiar because, besides common macromolecular humus-like dissolved organic carbon, it encompasses a number of specific compounds of pharmaceutical origin, including a suite of by-products deriving from the production of vitamin C. Since both macromolecular humic organic matter and vitamin C by-products are rather resistant to microbial degradation, leachate treatment procedures using simple retention lagoons or conventional bioreactors are not very effective in reducing their levels before the discharge into receiving waters. An attractive alternative is the application of membrane technology. The efficiencies of three different types of nanofilters for the purification of leachates from the Jakuševec landfill were examined. It was shown that both complex humic-like dissolved organic matter and anthropogenic compounds of pharmaceutical origin can be eliminated at high efficiencies, mostly above 90 %.
