本文指出，在配水系统中维持的理想氯浓度范围非常窄，可以集中在0.1 mg/L的值上。由于氯的消耗，整个配水系统中的残余氯的维持非常困难。为了实现这一目标，有必要降低氯消耗的主要参数（有机物、氯需求量、腐蚀），并实施能够对氯残留进行实际管理的工具，如水质建模、在线监测和再氯化升压站。

This paper points out that the ideal chlorine concentration range to be maintained within distribution systems is very narrow and could be centered on a value of 0.1 mg/L. Due to chlorine consumption, the maintenance of this residual throughout the distribution system is very difficult. To reach this objective, it is necessary to reduce the main parameters responsible for the chlorine consumption (organic matter, chlorine demand, corrosion) and to implement the tools which allow a real management of chlorine residuals such as water quality modeling, on line monitoring and rechlorination booster station.
