这项研究的目的是有效地去除饮用水中的浊度，以便在使用“直接”过滤的处理厂中用作多重屏障。泡沫过滤器在去除浊度方面的过滤性能是使用三种不同的泡沫在不同的压缩程度下处理的。泡沫过滤器用于过滤5微米大小的二氧化硅颗粒。还研究了headloss的发展。最后，比较了聚氨酯泡沫过滤器与砂和无烟煤的除浊性能。包括2个参考文献、表格和图表。

The goal of this study was to effectively remove turbidity from drinking water so that it can be used as a multiple barrier in treatment plants using "direct" filtration. The filtration performance of the foam filter with respect to removing turbidity is addressed using three different foams at varying degrees of compression. The foam filters were used to filter five micron-sized, silica particles. The headloss development also was studied. Finally, the turbidity removal performance of the polyurethane foam filters was compared with that of sand and anthracite. Includes 2 references, tables, figures.
