一、水处理剂的应用领域

在工业用水领域中,主要是应用于工业循环水处理和工业锅炉水处理。工业循环水处理使用的药剂主要有阻垢剂、缓蚀剂、杀菌灭藻剂、清洗剂、预膜剂等。工业锅炉水处理的常用方法有锅外水处理和锅内水处理,使用的药剂主要有:缓蚀阻垢剂、除氧剂、给水降碱剂、离子交换剂、再生剂、软化剂、碱度调节剂、清垢剂等。

市政/饮用水处理涉及到的水处理药剂一般有:杀菌灭藻剂、絮凝剂、缓蚀剂等。

污水处理涉及到的水处理药剂一般有絮凝剂、污泥脱水剂、消泡剂、螯合剂、脱色剂等。

海水淡化的主流技术包括蒸馏法和膜法。膜在运用中很容易被堵塞,所以需要在水中添加阻垢缓释剂、清洁剂、絮凝剂、阻垢分散剂等药剂。而蒸馏法容易产生锅垢从而降低蒸发效率,可以向原水中加入聚磷酸盐、有机磷酸,膦基聚羧酸等进行水质软化,对钙,镁离子以及其他金属离子螯合作用使其不易沉淀,阻止水垢的形成。
