  • What is polyaluminum chloride coagulant?
  • 1. Introduction Polyaluminum chloride (PAC) coagulant has been developed and used in water and wastewater treatment since the 1980s throughout the world (Jiang, 2001). PAC is made by partial hydrolysis of acid aluminum chloride solution using a specific reactor.
  • 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.
  • What are composite coagulants based on Pac and natural polyelectrolytes?
  • The composite coagulants based on PAC and natural polyelectrolytes are of great interest compared to PAC alone because of their efficiency, simplicity, and biodegradability of biopolymers.

  • What are composite coagulants?
  • Composite coagulants of polyaluminum chloride (PAC) and natural polyelectrolytes have attracted considerable attention in recent years due to their outstanding properties in drinking water treatment.
