  • 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.
  • What is polyaluminum chloride coagulant?
  • 1. Introduction Polyaluminum chloride (PAC) coagulant has been developed and used in water and wastewater treatment since the 1980s throughout the world (Jiang, 2001). PAC is made by partial hydrolysis of acid aluminum chloride solution using a specific reactor.
  • Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?
  • At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.
  • 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 occulation material for water treatment. In this work, PAC has been used as a Lewis acid catalyst
