CAS 1327-41-9 Yellow Powder Coagulant Polyaluminium Chloride PAC for Coal Washing Industry
Product Description:
- PAC-02 is a type of inorganic polymer coagulant, available in a light yellow, spray-dried powder form. Its Al2O3 content is more than 30%, and it has a high basicity of 70-90%.
- Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculants , furthermore, the treatment cost is lowered by 20%-80%.
- The dosage is smaller than that of other flocculants. It has wide adaptability to the waters at different emperatures and different regions.
- PAC-02's high basicity allows it to neutralize the acidic properties of water, while the high Al2O3 content contributes to its excellent coagulating properties. The powder form of PAC-02 is easy to handle and transport, and its effectiveness makes it suitable for use in a wide range of water treatment applications.

Features:
Polyaluminum chloride (PAC) can be used in a wide range of industrial and potable applications. It is easily soluble in water and rapidly dissolves. The cost of PAC is low, making it a very competitive option in comparison to other common coagulants. The dosage required is 20-50% lower than that of the drum drying PAC, it also boasts fast flocs forming ability, with strong activity and filterability. There is no need to add any additional alkaline additives and PAC can still maintain its efficacy even with deliquescence. It can also be adapted to a wide range of pH values and is highly versatile making it an ideal solution to many environmental problems. Additionally, the use of PAC can significantly reduce the salt content in the effluent, removing water pollution of heavy metals and radioactive substances. It also has a high active ingredient making it convenient for storage and transportation.
