在中试规模的配水末端管道系统中进行了实验，以确定余氯浓度与系统变量之间的关系。这些变量包括流速、生物量浓度和生物膜密度，以及氯浓度。实验装置是一个死端分配管的原型。在不同的流动条件下，对该系统的水力分散和氯浓度进行了研究。氟化物被用作示踪剂，以估算作为雷诺数函数的氯扩散系数。 包括参考，数字。

Experiments were conducted in a pilot-scale water distributiondead end pipe system to define relationships between chlorine residual concentrations and system variables. These variables included flow rate, biomass concentration and biofilm density, and chlorine concentrations. The experimental apparatus is a prototype of a dead-end distribution pipe. Hydraulic dispersionand chlorine concentrations in this system were studied under various flow conditions. Fluoride was used as a tracer to estimate chlorine dispersion coefficients as a function of Reynolds number. Includes reference, figures.
