  • Is polyaluminum chloride a Lewis acid catalyst?
  • Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment. In this work, PAC has been used as a Lewis acid catalyst in inte
  • Can polyaluminum chloride be used in water treatment?
  • In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.
  • Are aluminum chloride solutions effective coagulants for clay suspensions?
  • Partially neutralized aluminum chloride solutions were reported by Bottero et al. (1980) to be effective coagulants for clay suspensions.
  • What alumina content is suitable for sewage treatment?
  • Typically, PAC with alumina content below 26% is suitable for urban domestic sewage treatment and municipal sewage treatment with low turbidity. On the other hand, the 28% industrial-grade PAC is ideal for industrial wastewater treatment.
