ABSTRACT The chlorine bulk decay coefficient (kb) is a crucial parameter for modeling the process within drinking water distribution systems. In this study, combined effect of temperature and concentration on kb was investigated. A central composite design (CCD) employed. Ten scenarios were conducted pilot-scale pipeline network with initial concentrations from 0.38 to 4.62 mg/L 22.93 37.07 °C. statistical analysis obtained in experiments using STATGRAPHICS software. An variance (ANOVA) Log10(kb) also performed segregate contributions effects. Chlorine are factors that significantly affect kb. However, marginal compared concentration. quadratic model CCD data effectively predicted proposed experimental zone, although its utility may be limited at lower temperatures. shown response surface prediction Analysis revealed operating conditions 22.3 °C 3.33 mg/L, respectively, yield minimal value = 0.0347 h−1.

ABSTRACT In this paper, an inexact fuzzy random chance-constrained programming (IFRCCP) model was proposed to deal with the randomness and fuzziness in optimization of booster cost for water distribution system (WDS). The IFRCCP applied a WDS analyze effects on costs. intervals were obtained under various violation levels confidence levels. results indicated that lower upper costs increased limits decreased both normal log-normal variables (FRVs). Moreover, magnitude FRV is little less than FRV, while larger FRV. same regulation can be found FVR triangular trapezoidal FRVs. With increase number,
