  • 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 , .
  • Is polyaluminum chloride a good coagulant for water treatment?
  • Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
  • What are composite coagulants?
  • Composite coagulants of polyaluminum chloride (PAC) and natural polyelectrolytes have attracted considerable attention in recent years due to their outstanding properties in drinking water treatment.
  • Do polyelectrolyte composite coagulants improve coagulation performance?
  • El Foulani, Mohamed. Tahiri & Polyaluminum chloride (PAC)/natural polyelectrolyte composite coagulants have received considerable attention recently due to their exceptional properties in drinking water treatment. However, the criteria for selecting polyelectrolytes grafted into the PAC to improve coagulation performance are not yet well defined.
