Abstract

coliforms disinfection free chlorine monochloramine synergisms
The inactivation of E. coli by either free chlorine or combined chlorine present alone was determined. A completely stirred tank reactor (CSTR) was used. Both chemicals were then allowed to react simultaneously with E. coli in the same CSTR. The choice of the concentration of the chemicals allowed the comparison of the magnitude of the inactivation in the single and mixed system. It was demonstrated that the interaction between free chlorine and monochloramine in reacting with E. coli was synergistic. The experimental pH and temperature were 8 ± 0.03 and 20 ± 2°C, respectively.
