In a wastewater treatment plant, what is the PRIMARY purpose of the activated sludge process?
Randy
Nice work! The activated sludge process uses a mixed culture of
microorganisms - primarily bacteria - in an aeration basin to break down dissolved
and suspended organic matter. The key is maintaining the right balance of food
(BOD), microorganisms (MLSS), and oxygen. This drives biological oxygen demand
removal before the water moves to secondary clarifiers. Remember: Return
Activated Sludge (RAS) keeps the bug population healthy!
