Polyaluminium chloride (PAC) is a widely used for water purification. It has a wide range of PH adaptation and it is not easy to produce color or other side effects. After the use of poly aluminum chloride, the content of iron, manganese and other heavy metals in water is low, which has a little corrosive effect on the equipment. For this reason, it plays a special role in the treatment of papermaking waste-water, printing and dyeing waste-water.
Poly aluminium chloride in water treatment has the characteristics of good coagulation performance, large alum particles, fast settling, low dosage, high efficiency, and wide application range. So it mainly used in treating urban drinking water and all kinds of industrial waste-water. This product can also be used to remove iron, manganese, chromium, lead and other heavy metals in water, fluoride, and oil in water, so it is used to treat printing and dyeing, papermaking, oilfield sewage, urban sewage, and sludge dehydration treatment process. Due to the positive charge of polyaluminum chloride, it has strong adsorption of suspended matter in water. For this reason, it has many advantages such as strong decontamination, high comprehensive efficiency in oil removal and turbidity removal, low cost, etc. It also can be used in casting, medicine, leather, and other fields.
Because of its good stability, the PAC dosing can be reduced under the same water quality. Especially in the case of poor water quality, the dosage of poly aluminum chloride can be reduced by half. It not only reduces the labor intensity of workers but also reduces the water production cost of users. In addition, PAC in water treatment can ensure safety, reduce water accidents, and provide safe and reliable drinking water for residents.
