  • Why are aluminium based polymers used in water treatment?
  • These shortfalls in the use of alum have led to the synthesis of improved, aluminium-based polymers, which have been used extensively, over the few last decades, for treating water due to their high efficiency at lower dosages, and wider pH and temperature application ranges ( Sahu & Chaudhari 2013 ).
  • 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.
  • 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.
  • Does aluminum sulfate coagulation–flocculation treatment improve water quality?
  • Therefore, continuous research is necessary to improve water treatment methods and guarantee its quality. As part of this study, the effectiveness of coagulation–flocculation treatment using aluminum sulfate (Al 2 (SO 4) 3) was evaluated on a very polluted site.
