The SBR is a fill-and-draw activated sludge system. Wastewater is added to a single batch reactor, treated to remove undesirable components, and then discharged. Equalization, aeration, and clarification are all achieved in one reactor — two or more reactors run a predetermined sequence to keep flow continuous.
Click any vessel to read what it does.
The water level, aeration, settling, and decant sequence are shown inside the same vessel to make the batch logic immediately legible.
Aeration and mixing remove BOD while controlled aerobic and anoxic periods support nutrient removal.
Follow the numbered train from inlet to treated-water reuse. Click any stage for its engineering note.
Screening ahead of the reactor removes coarse solids and grit.
Equalization, primary clarification, biological treatment and secondary clarification in a single reactor vessel.
Requires small space — minimal footprint.
Controllable react time and quiescent settling.
High nutrient removal capability, including biological nitrogen and phosphorus removal.
BOD removal efficiency generally 85 to 90%.
Filamentous growth elimination through controlled fill strategy.
