'''Sedimentation or Thickening Ponds are simple settling ponds that allow the sludge to thicken and dewater. The effluent is removed and treated, while the thickened sludge can be treated in a subsequent technology.'''
The thickened sludge must be removed mechanically (front end loader or specialized equipment) when the sludge has thickened sufficiently.
