Fourcommonflocculationagentsforwatertreatment四种水处理常见絮凝药剂

一、PACPolyaluminiumChloride聚合氯化铝是一种无机高分子混凝剂。主要通过压缩双层、吸附电中和、吸附架桥、沉淀物网捕等机理作用，使水中细微悬浮粒子和胶体离子脱稳，聚集、絮凝、混凝、沉淀，达到净化处理效果。Polymericaluminiumchlorideisaninorganicpolymericcoagulant.Mainlythroughcompressionofthedoublelayer,adsorptionofelectricneutralization,adsorptionofbridging,precipitatesnetworkcaptureandothermechanisms,sothatfinesuspendedparticlesandcolloidalionsinwaterdestabilization,aggregation,flocculation,coagulation,precipitation,toachievepurificationtreatmenteffect.
