These tanks, also called Most important clarifiers, offer about two hrs of detention time for gravity settling to occur. As being the sewage flows via them gradually, the solids gradually sink to the bottom.
Aerated wastewater then flows to final settling tanks, in which the heavier solids settle to The underside. We take out most of this secondary sludge and Incorporate it with the main sludge for thickening and digestion.
