  • What flocculants are used in water treatment?
  • Aluminium-based Flocculants: Aluminium sulphate (alum) is the most common aluminium-based flocculant used in water treatment. Its effectiveness is attributed to its ability to neutralise the electrical charges on colloidal particles, promoting their aggregation and subsequent sedimentation.
  • 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.
  • Can flocculants improve water quality?
  • As the need for efficient and effective water treatment continues to grow, interest in innovative approaches such as using flocculants to enhance water quality has surged.
  • What is polyaluminum chloride (PAC)?
  • RSC Adv. 2021 Dec 22; 12 (2): 655–663. Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment.
