Coagulation as the First Step in Wastewater Treatment

  • H. Ødegaard


In this paper contamination in municipal wastewater is characterized in terms of particle size, and the fate of particles in biological treatment is discussed. Based on this, it is concluded that coagulation, used as the first step in wastewater treatment, is rational. To demonstrate what is achievable by coagulation of raw wastewater, treatment results from over 100 Norwegian chemical treatment plants are presented.
