This paper reports the experimental results of a pilot-scale (100 mVh) investigation, carded out at the West Bari (S. Italy) municipal wastewater treatment plant, focused on parasite removal and disinfection by-product (DBP) formation during the UV disinfection of clarified (CL) and clarified-filtered (F) secondary municipal effluents at doses necessary for achieving the Italian microbial limit for unrestricted reuse ofwastewater in agriculture (2 CFU/ 100ml of total coliforms). The investigation demonstrated that parasites like Giardia lamblia cysts and Cryptosporidium parvum oocysts were both significantly affected by UV radiation and that potential UV-promoted formation of DBPs (nitro-phenols and N-nitroso-amines) did not occur according to GC/MS and LC/MS analytical evidences. O&M costs ranged from ~ 17.5 up to E 35/1000 m 3 for effluent F and CL respectively.

The investigation demonstrated that parasites like Giardia lamblia cysts and Cryptosporidium parvum oocysts were both significantly affected by UV radiation and that potential UV-promoted formation of DBPs (nitro-phenols and N-nitroso-amines) did not occur according to GC/MS and LC/MS analytical evidences.
