A new theory regarding the behavior of activated sludge in a sedimentation tank has been developed, based on the principles of momentum preservation in suspended sludge, the ratio between drag and gravity, and the potential energy of the sludge blanket. Field tests enabled the determination of new criteria for the functioning of secondary sedimentation tanks complying with this new theory.
