Escherichia coli bacteria inactivation employing ozone and ultraviolet radiation using a reactor with continuosly flowing water
2019
The study on the inactivation of Escherichia coli (E. coli) bacteria in water flowing continuosly in a treatment system based on two different reactors is presented. The bacteria inactivation is achievedin a water volumer of 500 mL inoculated with an E. coli concentration of 1000-1100 ppm and, subsequently, transferred to a rectangular geometry reactor subjected to UV radiation with an energy per volume of 1.44 J/mL. Inactivation efficiency of E. coli bacteria in the water of 99.32% was attained in a total treatment time of 180 seconds.
