  • 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.
  • Does polyaluminium chloride coagulate with non-prehydrolysed aluminium salts?
  • Although the mechanism of coagulation with non-prehydrolysed and prehydrolysed aluminium salts is the same, the presence of polymeric forms of aluminium in polyaluminium chloride solutions makes them more stable in water, providing more effective removal of impurities and lower concentrations of aluminium remaining in the treated water.
  • What are the different types of polyaluminium chloride?
  • Different varieties have been synthesized, including polyaluminium chloride (PAC), aluminium chlorohydrate (ACH) and polyaluminium sulphate (PAS) ( Pernitsky & Edzwald 2006 ).
  • What is aluminium sulphate (alum)?
  • * Local tax will be added as applicable Aluminium sulphate (alum) is among the most widely applied coagulant agents, used mainly for the treatment of drinking water. The conventional treatment processes applied in most large‐scale drinki...
