Sequential Batch Reactors (SBR)
The diligent Operator must be aware of following SBR conditions:
Know Your Flow Rate Throughout the Day
• Is the flow rate low, average or high?
• If the facility has a flow equalization tank, know the level of the tank throughout the day.
Observe the Aeration Tank Surface during the React phase
• Is there even air diffusion across the entire surface of the tanks?
• Look for dead spots (diffusor clogs) or blow outs (diffusor rupture)
• Know the DO levels throughout the React (Aeration) phase
Observe the Settling Tank Surface
• What is the target Settling phase blanket depth?
• How is the blanket depth trending from day to day?
• Is there gasification or solids observed floating on the surface?
