In activated sludge process, the detention period is only for 2 hours. So quick treatment.

In sedimentation tank, 30 to 35% of settleable organic matter can be removed.

Activated sludge process can remove 50 to 60% of soluble organic matter.

That is why mostly we recommended for these two treatment units.
