聚合氯化铝，简称PAC，是一种多羟基，多核络合体的阳离子形象封锁机高分子絮凝剂。固体产品外观为淡黄色或红黄色粉沫，其分子为[AL2(OH)nCL6-n]m,n≤5 m≤10，由于分子中带有数量不等的羟基，当聚合氯化铝加入 混浊源水后，在源水的PH条件下继续水解，在水解过程中，伴随着有发生凝聚，吸附，沉淀等一系列物理化学过程，从而达到净化目的。
    本产品的显著特点是净水效果明显，絮凝沉淀速度快，适应PH范围宽；对管道设备腐蚀性低，能有效地去除水中色质SS，COD，BOD及砷、铅、汞等重金属离子，制水成本低，效力大，用量小，操作简单，节省人力，物力，该产品广泛用于饮用水，工业用水和污水处理领域。

Chloride, referred to as the PAC, is a multi-hydroxy, complex multi-core image of the body block the cationic polymer flocculant machine.Solid appearance of the product powder is light yellow or red and yellow, the numerator is [AL2 (OH) nCL6-n] m, n ≤ 5 m ≤ 10, the molecules with varying amounts of hydroxy, when the PAC to joinsource water turbidity, PH in the source water conditions continue to hydrolysis, the hydrolysis process, accompanied with the condensate, adsorption, precipitation and a series of physical and chemical processes, so as to achieve the purpose of purification.
    The product is characterized by a significant water effect is obvious, flocculation and sedimentation speed, wide adaptation PH; low corrosion on the pipeline equipment, can effectively remove the water-color quality SS, COD, BOD and arsenic, lead, mercury and other heavy metal ions, low costof water, the effectiveness of large amount of small, simple operation, saving manpower, material resources, which are widely used in drinking water, industrial water and wastewater treatment.
