Poly aluminium chloride (PAC) is a new type of high-performance inorganic polymer flocculant. It is an inorganic polymer synthesized by aluminum chloride, aluminum hydroxide, alumina or other inorganic aluminum compounds with hydrochloric acid. PAC powder is very soluble in water, so it has the features of wide application range of PH value, large granule and fast settling speed. Therefore, PAC poly aluminum chloride is mainly used for industrial wastewater, drinking water, swimmin pool water,etc.
In terms of form, PAC chemical for water treatment can be divided into two types: solid powder and liquid. The solid poly aluminium chloride powder is divided into white, light yellow, golden yellow and brown according to different colors, and its corresponding liquid is colorless and transparent, slightly yellow, light yellow to yellowish brown. And their alumina content is also different. Usually, poly aluminium chloride with different colors will have certain differences in application and production process.
White PAC powder 30% for drinking water treatment is called high purity iron-free white or food grade poly aluminium chloride. Compared with other grade poly aluminum chloride, white PAC is the highest quality product. The main raw materials are high-quality aluminum hydroxide powder, Hydrochloric acid, the production process of white PAC chemical adopts the most advanced technology spray drying method in China. White poly aluminium chloride can be used in paper sizing agent, sugar decolorization and clarifying agent, tanning, medicine, cosmetics, precision casting and water treatment and other fields.
The light yellow PAC chemical is mainly used for drinking water treatment, especially strict restrictions on the content of heavy metals. Generally, the treated water is clear without precipitation, the content of Al2O3 is about 30 (±0.5), the powder is fine, the particles are uniform, the flocculation effect is good, the purification is efficient and stable, the dosage is small, and the cost is low.
The production process is spray drying method, and the raw material is aluminum hydroxide powder, hydrochloric acid and calcium aluminate powder.
The production process is drum drying method. It is also the most widely used high-efficiency flocculant in the market, and it has good flocculation effect in sewage treatment. Therefore, the gold yellow poly aluminum chloride PAC is the best choice for industrial water supply, industrial wastewater, industrial water cycle and urban sewage treatment.
For brown polyaluminum chloride, its production process is drum drying method, which has the excellent effects in sewage treatment. The raw materials are calcium aluminate powder, hydrochloric acid, bauxite and iron powder. Generally speaking, the more iron powder added, the darker the color will be. So the iron content is higher than other poly aluminum chloride. It is a water treatment product produced according to the special requirements of individual customers for water treatment.

Main Applications of Poly Aluminum Chloride
PAC poly aluminum chloride can be used as a flocculant or coagulant for water treatment, including drinking water, industrial wastewater, urban waste water, swimming pool,etc. In addition, PAC chemical is also used in foundry, medicine, leather, paper industry and so on.
Performance Characteristics of PAC Chemical
- High-efficiency water purification capacity. Generally, the water quality after PAC purification is better than traditional flocculants such as aluminum sulfate, and can quickly purify suspended solids and pollutants in the water, including turbidity, chromaticity, organic matter and microorganisms. In addition, the flocs formed by poly aluminum chloride are formed quickly and settle quickly, with a larger processing capacity than traditional products such as aluminum sulfate, and the alkalinity in the consumed water is lower than that of various inorganic flocculants, so no or less alkalinity can be added.
- Wide adaptability. The PAC poly aluminium chloride chemical is suitable for a wide range of source water pH values (5.0-9.0), and can play a good flocculation effect under different pH conditions. And the poly aluminium chloride chemical can be applied to water bodies of different types and water qualities, such as groundwater, river water, lake water, etc., and can also be used under low temperature, low turbidity and low pH.
- Environmental protection and economy. Fengbai PAC chemicals are less corrosive, have good operating conditions, and less salt increase in treated water, which is conducive to subsequent treatment such as ion exchange treatment and high-purity water production. Although the production cost of PAC polyaluminium chloride may be slightly higher than some traditional flocculants, its water purification cost is relatively low, which can save costs for users.
- Unique physical and chemical properties. The solubility of poly aluminium chloride powder is better than that of traditional flocculants such as aluminum sulfate, and it is easier to disperse and play a role in water bodies. In addition, PAC chemical for water treatment has good chemical stability and is not easy to decompose or produce harmful substances, which is conducive to ensuring water quality safety.
- Wide range of uses. PAC poly aluminum chloride is not only used in conventional water treatment fields such as urban water supply and drainage purification and industrial water supply purification, but also widely used in the treatment of industrial wastewater, sewage, sludge and the recovery of certain slag in sewage. In addition, white polyaluminum amide has also replaced aluminum sulfate as a neutral sizing precipitant in the papermaking industry.
