  • Are poly-Aluminium chloride and aluminium sulphate effective coagulant agents?
  • The efficiency of poly-aluminium chloride (PACl) and of aluminium sulphate (alum), two commonly applied coagulant agents, was studied comparatively in this work, during full-scale experiments in a drinking water treatment plant.
  • Which coagulant is better PAC or aluminum sulfate?
  • Polyaluminum chloride (PAC) and aluminum sulfate (alum) are both commonly used as coagulants in water treatment processes, but PAC is generally considered a better option in terms of effectiveness and efficiency. Here are a few reasons why: Enhanced Coagulation Optimization: PAC has a higher charge
  • 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.
  • 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.
