  • What is a preformed polyaluminum salt?
  • Polyaluminum chloride (PAC) is a preformed polyaluminum salt that can be produced by adding base to aluminum chloride until an empirical formula of Al (OH)nCl3-n (with n from 1.0 to 2.5) is achieved. A variety of species can be formed when stock solutions of PAC are added to a raw water.
  • Does initial concentration of aluminum chloride affect the yield of Al B?
  • As observed in Fig. 1 (a–d), the effects of initial concentration of aluminum chloride, basicity ratio, reaction temperature and time curves were steep slope and curvature, which revealed that the yield of Al b content in the PΑC species was very sensitive for these factors.
  • Does calcium aluminate react with aluminum chloride to increase basicity?
  • It indicated that the method of increasing the basicity in liquid PACl is viable, calcium aluminate reacts with aluminum chloride (zero base) to generate a high basicity PACl (Eq. (2)). The sample A exhibited the highest aluminum content (13.7%) and the highest basicity (92.9%).
  • Does pH affect the performance of polyaluminum chloride (PAC)?
  • The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
