  • 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.
  • What is a preformed polyaluminum salt?
  • Polyaluminum chloride (PAC) is a preformed polyaluminum salt that can be produced by adding base to aluminum chloride until an empirical formula of Al (OH)nCl3-n (with n from 1.0 to 2.5) is achieved. A variety of species can be formed when stock solutions of PAC are added to a raw water.
  • Does poly aluminum chloride remove turbidity from aqueous solutions?
  • In this study, the application of poly aluminum chloride (PAC) as a chemical coagulant and rice starch as a natural coagulant aid to remove turbidity from aqueous solutions was investigated.
  • 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 ).
