The problem of high dosages of chlorine residuals near water sources and its lack in the remote points for
conventional chlorination of a water distribution system (WDS) has almost been solved by introducing optimal
location of booster disinfection system within a WDS. However, trihalomethane (THM) formation within the
WDS with a level higher than maximum allowable one still needs more attention to meet standard levels. This
paper presents a multi-objective booster disinfection approach in which both chlorine residuals and THM
formation are concurrently optimized in a WDS. In the first phase, a booster disinfection system is formulated as
a multi-objective optimization problem in which the objectives are defined as maximization of the volumetric
discharge with appropriate levels of disinfectant residuals within all demand nodes and minimization of the total
mass of disinfection applied with a specified number of booster stations. The most frequently selected locations
for installing booster disinfection stations are chosen for the second phase. The objectives in the second phase
are to minimize the volumetric discharge avoiding THM maximum levels and to maximize the volumetric
discharge with standard levels of disinfectant residuals. Optimal scheduling of mass of chlorine for each booster
station are then determined. The application of the model to a real WDS shows the effectiveness of this approach
for meeting two qualitative indicators in WDSs.
