  • 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.
  • 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.
  • 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.
  • Does polyelectrolyte gelling capacity affect coagulation performance in dam water treatment?
  • As a result, the gelling capacity of the polyelectrolyte is an important factor that should be taken into account in the development of new composite coagulants. The present study evaluated the coagulation performance of composite coagulants containing natural polyelectrolytes of different charges in dam water treatment.
