  • Is there an alternative preparation procedure for polyaluminium chloride (PAC)?
  • An alternative preparation procedure for polyaluminium chloride (PAC), a common inorganic coagulant, is presented in this paper.
  • 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.
  • 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 granular al be used to produce polyaluminium chloride?
  • An alternative way for the production of PAC should be desirable, resulting in a more effectively preparation route, regarding time and cost. In this paper, an alternative method for producing polyaluminium chloride is presented, based on the use of granular Al, as aluminium source.
