Organic and compound cation garrulous coagulates the agent is to use chemical law compound a kind of new-style cation garrulous coagulates agent, belong to domestic and international initiate, with other and groovy drug photograph comparing has 5 big advantages: The photograph such as aluminium of as aggregate as commonly used drug chloridize, aggregate and vitriolic iron, vitriolic aluminium is compared, coagulate with garrulous of polypropylene acyl amine the agent is used jointly, medical dose is little, reduce useless water treatment to expend about 20 ％ thereby, 30 ％; Effect of processing liquid waste is good, garrulous is round settling speed is fast, make liquid waste can second birth is used, managing water natural resources; Its garrulous group is sedimentary filterability can be good, slime can reclaim inside entire plant, namely energy-saving be helpful for protecting an environment again; Corrode to equipment small; Have muti_function, have agglomeration effect already, again garrulous coagulates action and the action that aid filter, can serve as filter aid.内容来自www.ch-water.com

有机复合阳离子絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂是利用化学法合成的一种新型阳离子絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂，属国内外首创，与其他常规药剂相比具有五大优点：与常用药剂聚合氯化铝、聚合硫酸铁、硫酸铝等相比，与聚丙烯酰胺类絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂联合使用，药剂量少，从而降低废水处理(通过物化方法去除水中一些物质的过程)费约20％—30％；处理废水效果好，絮团沉降速度快，使废水能再生利用，节约水资源；其絮团沉渣过滤性能好，煤泥可全部厂内回收，即节能又有利于保护环境；对设备腐蚀小；具有多功能，既有凝聚作用，又有絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)作用和助滤作用，可作为助滤剂。
