The baffle in a septic tank is there to control how wastewater leaves the tank and to keep solids from heading out into the drainfield. The inlet baffle slows and directs incoming wastewater so heavier solids can settle to the bottom, while the outlet baffle guides the clarified liquid to the septic effluent outlet and prevents scum or floating material from leaving with it. This setup reduces turbulence, helps the solids stay contained, and ensures the effluent entering the drainfield is relatively clear and evenly distributed. It does not primarily remove nutrients or provide odor control, and it does not increase mixing of the wastewater.
