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.
Application and General Dosage Reference:
- Suggested to dilute to the concentration of 2%-5% solution before use.
