  • What is the coagulation removal rate of polyaluminium chloride (PAC)?
  • Without coagulation removal rates in a single pass of a medium-rate filter were about 50%. This was dramatically improved, to over 90%, by dosing polyaluminium chloride. PAC is directly and continuously dosed from the containers in which it is delivered at a rate of about 0.1ml/m 3 of the circulation flow.
  • 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 polyaluminum chloride coagulate with hydrolyzed coagulants?
  • Coagulation with hydrolyzing coagulants has been studied thoroughly, but the coagulation behavior of pre-hydrolyzed coagulants such as polyaluminum chloride (PACl), especially the coagulation mechanisms at various coagulant dosages and pH values of raw water, has not been systemically investigated and not been well understood , .
  • What is the basicity of PACL powder?
  • Commercial PACl powder (Nanning Chemical Engineering Co. Ltd., Nanning, China), with a basicity (OH/Al) of 1.35 and Al 2 O 3 content of 30% (mass fraction), was dispersed into deionized water to prepare a concentrated stock solution (2 mol·L − 1 Al).
