  • 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.
  • Do high-poly-aluminum chloride sulfate coagulants remove humic acid?
  • High-poly-aluminum chloride sulfate (HPACS) coagulants with different [SO42−]/ [Al3+] molar ratio (S) were prepared and proved to have high coagulation efficiency for the removal of humic acid and strong stability for storage and application. The results showed that the higher the SO42− addition, the bigger the alum
  • Which coagulant is better alum or PACL?
  • (b) the direct filtration process, i.e., coagulation‐flocculation and sand filtration, but without the intermediate sedimentation step. PACl proved to be a more efficient coagulant than alum, as lower dosages of PACl, about 1.35 mg Al/L in this case, resulted to the production of treated water with low turbidity and residual aluminium content.
  • Which coagulants have high coagulation efficiency for humic acid removal?
  • High-poly-aluminum chloride sulfate (HPACS) coagulants with different [SO 42−]/ [Al 3+] molar ratio (S) were prepared and proved to have high coagulation efficiency for the removal of humic acid and strong stability for storage and application.
