  • 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 , .
  • Does polyaluminum chloride hydrolysis affect kaolin coagulation performance?
  • The effects of polyaluminum chloride (PACl) hydrolysis prior to coagulation on both the coagulation zone and coagulation performance of a kaolin suspension were investigated by a novel jar test named the “reversed coagulation test”.
  • Can polyaluminum chloride and diatomite improve coagulation performance?
  • The feasibility of using enhanced coagulation which combined polyaluminum chloride (PAC) with diatomite (as coagulant aid and adsorbent) for improving coagulation performance and reducing residual Al… This study investigated the frequent blockages observed in the discharge pipeline in the chemical mechanical polishing wastewater treatment plant.
