使用基于激光的粒度分析仪通过常规水处理和在线过滤来表征粒度分布的趋势。通过查阅有关颗粒分离和过滤孔絮凝的文献以及粒径分布实验的数据，开发了一个概念性过滤模型，该模型结合了颗粒附着和分离以及过滤床中的优先管（虫洞）流。包括27个参考文献、表格和图表。

A laser-based particle size analyzer was used to characterize trends in particle size distribution through conventional water treatment and through in-line filtration. Review of the literature on particle detachment and filter pore flocculation and of data from the particle size distribution experiments led to the development of a conceptual filtration model, which incorporated particle attachment and detachment, as well as preferential tube (wormhole) flow in the filter bed. Includes 27 references, table, figures.
