The sedimentation of particles are based on the gravity force from the di erences in density between particles and the uid. Sedimentation is widely used in wastewater treatment systems. A successful sedimentation is crucial for the overall eciency of the plant. Common examples include the removal of; ã  Grit and particulate matter in the primary settling basin (settling tanks that ã receive raw wastewater prior to biological treatment are called primary tanks, f  ã orsedimentering). ã Sludge from the bioreactor (activated sludge process). ã  Chemical flocs in the chemical step.
