These are water treatment processes which are based on the application of physical phenomena for the elimination of solid pollutants floating or suspended in the water, including the forces of gravity, centrifuge, cohesion and retention.

Examples of physical processes in wastewater treatment:

  • Discharge of solids
  • Degreasing
  • Desanding
  • Flotation
  • Evaporation
  • Sedimentation
  • Disinfection
  • Absorption
