聚合氯化铝的净水过程一般分为三个阶段。这三个阶段分别是凝聚阶段、絮凝阶段和沉降阶段。凝聚阶段在药液注入混凝容器与原水快速混凝时会在极短时间内形成微细矾花。此时水体变得更加浑浊,它要求水流能产生激烈的湍流。然后聚合氯化铝进入絮凝阶段,絮凝阶段是矾花成长变粗的过程,要求适当的湍流程度和足够的停留时间(10~15min),至后期可观察到大量矾花聚集缓缓下沉,形成表面清晰层。当絮凝剂处于沉降阶段时,它是在沉降池中进行的絮凝物沉降过程,要求水流缓慢,为提高效率一般采用斜管或板式沉降器,大量的粗大矾花被斜管(板)壁阻挡而沉积于池底,上层水为澄清水,剩下的粒径小、密度小的矾花一边缓缓下降,一边继续相互碰撞结大。但是和聚丙烯酰胺相比,其沉降效果远不如聚丙烯酰胺。聚合氯化铝的盐基度是聚铝中相对重要的指标,特别是针对饮用水级别的聚铝产品。盐基度越低,其价格越高,各采购商可以根据厂家的实际情况来操作。另外不同原材料,不同工艺生产处理的聚合氯化铝产品的盐基度也是不同,这就需要厂家来进行调整。提高聚氯化铝产品的盐基度,可大幅提高生产和使用的经济效益。盐基度从65%提高到92%,生产原料成本可降低20%,使用成本可降低40%。固体聚合氯化铝稀释成液体时,首先要根据原水情况,使用前先做小试求得***药量。在生产上使用聚合氯化铝时,按聚合氯化铝固体:清水=9-15质量比混合溶解即可。氧化铝含量低于1%的溶液易水解,会降低使用效果。
