Introduction
Polyaluminum ferric sulfate is also called polyaluminum ferric sulfate and composite aluminum ferric sulfate. Its main component is [Al(OH)nSO4]m[Fe2(OH)nSO4]m, which is developed on the basis of polyferric sulfate and polyaluminum sulfate It has the advantages of both the water purification effect of aluminum salt and the safety of iron salt without the harm of Chemicalbook. It also has the advantages of high salinity, large alum flower, fast flocculation settling, low dosage, high removal rate, and wide application fields. At present, it is mainly used for coagulation and turbidity removal, printing and dyeing wastewater treatment, coking wastewater treatment, wastewater treatment with heavy metal ions, dairy wastewater treatment, etc.
