非离子或阴离子聚合物在饮用水处理中主要用作絮凝剂。 虽然在美国和其他国家使用合成阳离子聚合物是一种常见做法，但在 法国卫生部刚刚批准了这些化学物质 用于饮用水的材料。阳离子聚合物混凝剂可以有效地增强混凝效果 用于地表水或直接过滤源水。使用这些凝固剂的试验已经完成 在2001-2003年期间，在实验室和中试规模进行，为饮用水的使用做准备 2004年期间，自来水厂达到了工业规模。 这项研究的重点是选择和评估技术和经济利益 使用阳离子聚合物作为饮用水的凝固剂。目的是确定 澄清过程性能，可在各种类型的水上实现，包括天然有机物（NOM）和 浊度去除和相应的化学品类型和剂量。被测试者的主要兴趣 聚合物被发现与矿物凝固剂联合使用:与铝盐结合使用 用于强化常规混凝，并与铁盐直接过滤。最优替代 矿物混凝剂与有机混凝剂的比例为30%。潜在副产品 在试验过程中，地层（NDMA）得到了控制。在通常操作条件下（聚合物 剂量和消毒剂残留）未形成NDMA，因此存在副产物形成的风险 被评估为非常低。包括28个参考文献、表格和图表。

Non-ionic or anionic polymers are largely used as flocculants in drinking water treatment. While the use of synthetic cationic polymers in the U.S. and other countries is a common practice, in France these chemicals have just received approval from the health and sanitary department as materials to be used for drinking water. Cationic polymeric coagulants can be efficient for enhanced coagulation of surface waters or for direct filtration of source waters. Tests with these coagulants have been performed during the 2001-2003 period, at laboratory and pilot scale, to prepare the use on drinking water works at industrial scale during 2004. This study focused on the selection and the assessment of the technical and economic interest for using cationic polymers as coagulants for drinking water. The objective was to establish the level of clarification process performance that can be achieved on various types of waters for both natural organic matter (NOM) and turbidity removal and the corresponding type and dose of chemical. The major interest of the tested polymers has been found to be their joint use with mineral coagulant: combination with aluminum salt for enhanced conventional coagulation and with ferric salt for direct filtration. The optimal substitution ratio of mineral coagulant by organic coagulant has been found to be 30%. Potential byproducts formation (NDMA) have been controlled during the tests. Under the usual operating conditions (polymer dose and disinfectant residual) no NDMA was formed and therefore the risk of byproducts formation was evaluated to be very low.
