在这项研究中，四种阳离子聚合物作为唯一的混凝剂用于去除合成水和天然水中的三卤甲烷前体。天然水使用的聚合物剂量为2.5至20 mg/L，而腐殖酸水使用的聚合物剂量为2.5至30 mg/L，黄腐酸水使用的聚合物剂量高达60 mg/L。由腐殖酸合成的水比由黄腐酸合成的水更易于聚合物凝结。高岭石的存在似乎改善了这些水域中三卤甲烷生成潜力（THMFP）的去除。总的来说，聚合物的性能相当。对于天然水，聚合物混凝在THMFP还原中的效果因原水来源而异。水的环境pH值似乎会影响聚合物的性能。对于这两种类型的水，THMFP的减少通常大于总有机碳的相应减少。 包括16个参考文献、表格和图表。

Four cationic polymers were tested in this study as sole coagulants for removing trihalomethane precursors from synthetic and natural waters. Polymer dosages of 2.5 to 20 mg/L were used with natural waters, whereas dosages of 2.5 to 30 mg/L were used with humic acid water and dosages up to 60 mg/L were used with fulvic acid water. Waters synthesized from humic acid were more amenable to polymer coagulation than those synthesized from fulvic acid. The presence of kaolinite appeared to improve removal of trihalomethane formation potential (THMFP) from these waters. In general, the performances of the polymers were comparable. For the natural waters, the effectiveness of polymer coagulation in THMFP reduction varied as a function of raw water source. Ambient pH of the water appeared to influence polymer performance. For both types of water, the reductions in THMFP were generally greater than the corresponding decreases in total organic carbon. Includes 16 references, tables, figures.
