Initial elements and results for the random choosing of chlorine injectionbooster stations.Minimum concentration : 0.20 mg/LMaximum concentration : 0.50 mg/LNodes for chlorine injections : 6 (1,4,7,8,11,12)Number of random choosing: 10Chlorine total consumptions : 2.488 kg./dayTime of program execution : 14 s.Efficiency (consumed chlorine /injected chlorine): 0.586Table 2 presents chlorine concentration at nodes for optimal solutionTable 3 presents the nodes with chlorine injections and injected quantity, in mg/L,corresponding to water flow rates transported in 24 hoursTable 2.
