Abstract In the present study, the effect of two different UV-LED wavelengths (255 and 265 nm) and their combination (255/265 nm) is investigated on the inactivation of antibioticsensitive and antibiotic-resistant E.coli. The tested antibiotics are Ampicillin, Ciprofloxacin, and Sulfamethoxazole at a concentration of 64, 4 and 512 mg/L, respectively. For the contaminated water, a synthetic greywater was created to be inoculated with the two strains of E. coli and its posterior disinfection by UV radiation with a lab-scale UV-LED equipment. The used equipment is capable to combine different wavelengths up to three at the same time. About 3-log reduction was obtained at lower concentrations (106 and 107 CFU/mL) at 5,5 mJ/cm2 fluence by a wavelength of 265 nm. |
