Polyaluminium chloride, abbreviated as polyaluminium chloride, or PAC. It is synthesized by reaction and polymerization using high-quality raw materials with advanced production process. Polyaluminium chloride is produced by spray drying process and is therefore also called polyaluminium chloride by spray drying.
PAC PAC polyaluminium chloride has the advantages of good spray drying stability, wide adaptability to water area, fast hydrolysis speed, strong absorption capacity, large alum formation, fast quality precipitation, low turbidity of effluent and good dewatering performance. Under the same water quality, the dosage of PAC polyaluminium chloride by spray drying is reduced by half, especially under the condition of poor water quality. It not only reduces the labor intensity of workers, but more importantly, reduces the cost of water production for users. In addition, spray drying products can ensure stability, reduce water accidents and are very reliable for drinking water of residents. Moreover, the purified water quality is better than that of aluminium sulfate flocculant and the cost of purified water is 15-30% lower than that of aluminium sulfate flocculant. The flocculent has the advantages of fast formation, fast settling speed and higher capacity than traditional products such as aluminium sulfate. Alkalinity of consumed water is lower than that of various inorganic flocculants, so alkali dosage can be avoided or reduced.
The adapted source water pH5.0-9.0 can be condensed. Small corrosiveness, good operating conditions. Solubility is better than that of aluminium sulfate. The increase of salinity in treated water is less, which is conducive to ion exchange treatment and high purity water production. The adaptability to temperature of source water is better than that of inorganic flocculants such as aluminium sulfate.
