The results presented in this figure are based on research aimed at investigating the correlation between the disinfection performance with the factors contact time t and residual chlorine CR in a long period of time (2 years) enabling to provide insights into the possible effects of the different seasons and related climatic conditions over this process. More specifically, the figure shows the experimental correlation between the efficiency ratio of E. coli removal by disinfection (Eo/E) with the product of chlorine residual with the contact time (CR .t).
