A general framework for modeling the bulk chlorine decay that accommodates effects of pH, temperature in water distribution system and in-home heating profiles is developed. With a single set of readily interpreted parameters, and various fictive concentrations of reactive constituents in the water, chlorine decay for the different water systems could be simultaneously modeled. Differential Evolution is employed to estimate the parameters stochastically. By using Bayesian Information Criterion, it is shown that a model consisting of two reactive species is preferred over models that consist of one or three reactive species. The flexibility and power of the framework is demonstrated with a case study of both types of effects.
开发了一个通用框架来模拟整体的余氯衰减，该框架考虑了 pH 值、水分配系统和家庭供暖曲线温度的影响。通过一组易于解释的参数，以及水中各种反应性成分的虚拟浓度，可以同时对不同的水系统进行氯衰减建模。使用差分进化来随机估计参数。通过贝叶斯信息准则，可以看出由两个反应性物质组成的模型优于由一个或三个反应性物质组成的模型。通过对这两种类型的影响进行案例研究，展示了该框架的灵活性和强大功能。
