Sažetak
Increased quantities of organics such as pesticides, pharmaceuticals and other organic micropollutants can be found today in the aquatic environment and are of great concern in drinking water, wastewater, and water reuse applications The membrane separation processes, reverse osmosis (RO) and nanofiltration (NF) are shown to be efficient and economical methods for removal of organic micropollutants. The objective of this study was to examine the removal efficiency of antibiotics from realwastewater of a manufacturing plant producing pharmaceuticals for veterinary use. The efficiency of three RO/NF membranes to remove some frequently used antibiotics and other organics from wastewater was determined. For this investigation five antibiotics were used: sulfaguanidine (SGUA), sulfadizine (SDIAZ), sulfamethazine (SMETH), trimethoprim (TMP), enrofloxacin (ENRO). Three different membrane elements were chosen: the RO membrane XLE from Dow/FilmTec, Midland MI and two NF membranes: NF90 from Dow/FilmTec and HL Desal, Osmonics, GE Infrastructure Water Process Techn., Vista, CA. The membranes were tested in pilot-plant unit installed at "Veterina", Kalinovica near Zagreb. The wastewater experiments were performed in the batch circulation mode in order to avoid the membranes' fouling, because the pilot unit did not include a comprehensive pretreatment section. Before the introducing this wastewater into the pilot unit, it was treated by a coagulation/flucculation and subsequent filtration using a filtering cloth to eliminate the suspended floccules. After that it was spiked with the selected antibiotics in addition to some antibiotic material already present in the wastewater. The performance results show the complete removal of all the antibiotics by the RO membrane and by the tight nanofiltration membrane NF90. Only the loose nanofiltration membrane element HL incompletely removed the smaller sulfonamide antibiotics.
