  • What is coagulation flocculation?
  • The coagulation flocculation is considered the most important process in water surface treatment. Coagulation allows by the injection and the scattering of chemical (coagulants) during relatively intense mixing to destabilize naturally occurring particles and macromolecules and/or to precipitate additional particles (Mackenzie and Cornwell 1991).
  • What particles are removed from raw water by coagulation and flocculation?
  • The particles being removed from raw water by coagulation and flocculation are either suspended or colloidal and are composed of clay and other inorganic materials, organic substances, bacteria, viruses, and even color.
  • When were coagulants used in water treatment?
  • The modern use of coagulants for water treatment started more than 100 years ago, when ferric chloride and aluminum sulfate were used as coagulants in full-scale water treatment works.
  • What is coagulation used for?
  • Coagulation is applicable for the removal of various impurities from water, including colloidal particles as well as some dissolved substances [, , , 12].
