  • 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 is covered in coagulation flocculation?
  • The chapter develops theoretical aspects of colloidal systems, their stability, and the interactions between particles. The coagulation-flocculation process is also described, as well as the influencing factors (temperature, pH, water composition, among others).
  • What coagulants are used in water treatment?
  • The most widely used coagulants in water treatment arealuminum sulfate and iron salts. turbidity, suspended solids, temperature, pH, cationic and anionic composition and concentration, duration and degree of agitation during coagulation and flocculation, dosage and nature of the coagulant, and, if required, the coagulant aid.
  • Why is water treated with coagulation and flocculation?
  • Before we look in detail at the coagulation and flocculation process, you might be wondering – why is water treated with this method?
  • The main purpose of coagulation and flocculation is to treat turbid (hazy or cloudy) water, thus improving water quality.
