  • 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.
  • Can polyaluminium chloride improve coagulation process in conventional water treatment?
  • The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.
  • Why is poly aluminum chloride a good coagulant?
  • Poly aluminum chloride has become one of the most common coagulants used due to its good performance in removing more particles and consuming less alkalinity and producing less sludge (Abdo et al., 2025; Ghafari et al., 2009, 2010). Starch is a natural, cheap, and abundant substance in the world.
