Abstract
Disinfection using UV irradiation has been considered to an alternative for chlorination because it does not suffer from disinfection byproducts problem. The aim of this study was to verify if UV irradiation with 368.6[nm] wavelength has a potential to be used a efficient disinfection. UV irradiation was given for 60 minutes to E. coli. which was used as a model microorganism. Remarkable decrease in number of microorganism was not observed for initial 30 minutes, however, 83.3[%] of disinfection efficiency was achieved after 30 minutes of irradiation. Inactivation constant, k was determined to 0.00868[$cm^2$]/([$mW{\cdot}s$]) using kinetic approach.
