明矾和高分子量、带弱电荷的阳离子聚合物的组合可最有效地去除总有机碳和浊度，与单独使用明矾相比，可减少产生的污泥量，并以较低的成本实现这些目标。本文报告的结果基于实验室规模的批量或罐式试验。包括4个参考文献、表格和图表。

A combination of alum and a high-molecular-weight, weakly charged cationic polymer produced the most effective removals of total organic carbon and turbidity, reduced the volume of sludge produced when compared with alum alone, and accomplished these objectives at reduced costs. The results reported in this paper are based on laboratoryscale batch or jar tests. Includes 4 references, tables, figures.
