这项研究解决了由于颗粒物导致客户水龙头变色的问题。Slaats等人（2003年） 描述了这个问题，并解释了一种研究管道在水中污垢行为的方法 饮用水分配系统。这项研究描述了一种新的建模方法 在设计为管道回路的小型试验装置中，水中颗粒的行为。研究结论发现，仅使用一个参数来描述取决于水力条件的颗粒移动的常规做法是不够的。更准确的假设是沉积物和附着物的部分移动。当超过临界水剪应力时，并非所有沉积物都会被移动。由于大多数力的变化影响，颗粒在管流中的沉降速度会发生变化，并取决于管道横截面的高度。重要的是考虑凝聚力和粘附性，由于小颗粒大小，从而影响沉降和运输的事实，大多数沉积物不沉降，但形成壁附着。 包括8个参考文献、图表。

This study addresses the occurrence of discolored water at the customers tap due to particulate matter. Slaats et al. (2003) describes the problem and explains a method to investigate the fouling behavior of pipes in drinking water distribution systems. This study describes a new approach to modeling the behavior of particles in water at a small scale pilot plant designed as a pipe loop. Study conclusions found that the common practice of using only one parameter to describe the mobilization of particles dependent on hydraulic conditions is insufficient. It is more accurate to assume the partial mobilization of sediment and attachments. Not all sediment is mobilized when a critical water shear stress is exceeded. The settling velocity of a particle in the pipe flow varies and depends on the height of the pipe cross section due to the changing influence of most forces. It is important to consider cohesion and adhesion due to the small particle sizes, thus influencing the settling and transport by the fact that most of the sediment does not settle but forms wall attachments.
