本研究调查了影响低浊度水中颗粒物去除程度的参数，包括快速混合和过滤。不同的参数包括快速混合速度梯度、阳离子聚电解质类型和聚电解质用量。通过膜渗透压法、光散射法和高效液相色谱法对阳离子聚电解质的分子量进行了表征。过滤动力学变量，包括最大深度平均单收集器效率和比沉积，用于表征72次过滤器运行的颗粒去除效率。统计分析表明，聚电解质的选择是唯一重要的因素。 此外，对过滤器中深度样品的颗粒计数数据进行的体积尺寸分布分析表明，聚电解质结构可能对聚电解质在过滤过程中吸附到颗粒和介质上至关重要。包括18个参考文献、表格、图表。

This research investigated parameters influencing the degree of particulate removal from low turbidity water in a configuration that included rapid mixing followed by filtration. The varied parameters were rapid-mixing velocity gradient, cationic polyelectrolyte type, and polyelectrolyte dosage. The cationic polyelectrolytes were characterized for molecular weight by membrane osmometry, light scattering, and high performance liquid chromatography. The filtration kinetics variables, including maximum depth-averaged single-collector efficiency and specific deposit, were used to characterize the efficiency of particulate removal for each of 72 filter runs. Statistical analyses demonstrated that the choice of polyelectrolyte was the only significant factor. Additionally, volume size distribution analyses of particle count data from in-depth samples in the filter demonstrated that the polyelectrolyte configuration may be critical for adsorption of polyelectrolytes to particulates and media in filtration.
