  • Does polyaluminum chloride coagulate with hydrolyzed coagulants?
  • Coagulation with hydrolyzing coagulants has been studied thoroughly, but the coagulation behavior of pre-hydrolyzed coagulants such as polyaluminum chloride (PACl), especially the coagulation mechanisms at various coagulant dosages and pH values of raw water, has not been systemically investigated and not been well understood , .
  • 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.
  • What is the coagulation time for aluminum sulfate and aluminum chloride coagulants?
  • However, for aluminum sulfate and aluminum chloride coagulants the coagulation time and settling time were reached to 15 and 35 min, respectively. The results revealed that the residual aluminum concentration in the treated water was very small for synthesized PAC coagulant which was <0.2 mg L −1.
