28% Polyaluminum Chloride
28% polyaluminum chloride product overview:
28% polyaluminum chloride is an inorganic polymer coagulant, also known as polyaluminum or PAC in English. It is an inorganic polymer water treatment agent with large molecular weight and high charge produced due to the bridging action of hydroxide ions and the polymerization of multivalent anions.
28% polyaluminum chloride is mainly used for water purification: domestic water and industrial water; Urban sewage treatment; Treatment of industrial wastewater, sewage and sludge and recovery of some residues in sewage; For some industrial sewage with great difficulty in treatment, PAC is taken as the matrix, mixed with other agents, and mixed into composite PAC, which can achieve surprising results in sewage treatment.
28% polyaluminum chloride product specification:

Applications fields of 28% polyaluminum chloride:
1. Water purification: domestic water and industrial water;
2. Urban sewage treatment;
3. Treatment of industrial wastewater, sewage and sludge and recovery of some residues in sewage;
4. For some industrial sewage with great difficulty in treatment, PAC is taken as the matrix, mixed with other agents, and mixed into composite PAC, which can achieve surprising results in sewage treatment.
Advantages of 28% polyaluminum chloride:
Due to the advantages of spray drying, such as good stability, wide water area, fast hydrolysis speed, strong adsorption capacity, large alum formation, fast quality density and sedimentation, low turbidity of outlet water, good dehydration performance, etc., the dosage of spray type polyaluminum chloride is reduced under the same water quality, especially when the water quality is poor, the dosage of spray drying products can be reduced by half compared with roller drying polyaluminum chloride, It not only reduces the labor intensity of workers, but also reduces the water production cost of users. Polyaluminum chloride, referred to as polyaluminum chloride, or PAC. It is formed by reaction polymerization of raw materials with high degree of use using the most advanced production process at present. All the quality indicators have reached or even exceeded the requirements of the national standard gb15892-2009. Polyaluminum chloride is processed by spray drying process, so it can also be called spray drying polyaluminum chloride. Characteristics of polyaluminum chloride product: it has the characteristics of fine powder, uniform particle, easy to dissolve in water, good flocculation effect, stable purification, small dosage and low cost. Suitable for drinking water purification, urban water supply purification and industrial water supply purification; It is applicable to source water of various turbidity, with a wide range of pH, large and fast alum formation and fast sedimentation.
28% polyaluminum chloride product features:
1. The flocs have fast forming, good activity and good filterability.
2. There is no need to add alkaline additives. In case of deliquescence, its effect will not change.
3. It has wide pH value, strong adaptability and wide application.
4. The treated water has less salt.
5. It can remove water pollution caused by heavy metals and radioactive substances.
6. High effective ingredients, easy to store and transport.
28% polyaluminum chloride packaging and storage:
1. Liquid products can be transported in tank cars or plastic barrels, and can be stored in the pool with a storage period of one year.
2. Solid products are packed in plastic woven bags lined with plastic film bags, with a net weight of 25kg each.
3. Solid products are easy to absorb moisture and deliquesce (after deliquescence, the use effect will not be affected), and should be stored in a ventilated and dry place. The storage period of solid products is one year.
4. This product shall not be mixed with hazardous substances for storage.
