Troubleshooting SBRs


  • October 20, 2021
    9:00 am - 12:30 pm

This class reviews the biology and chemistry involved in all phases used during a sequencing batch reactor (SBR) cycle. Phases involved include: 1) static, mix or anoxic and aerated fill phases and single and step fill phases; 2) react phase; 3) settle phased; 4) draw or decant phase; and 5) idle phase or period. The goals of each phase—nitrification, denitrification, biological phosphorus release, biological phosphorus uptake, and oxidation of cBOD using dissolved oxygen–will be discussed. A review of the roles of the bacteria involved in each phase is presented along with the expected changes (biological, chemical, and physical) in critical tests that can be used to monitor the success of each phase. Worksheets are provided for operator use to determine if the time of a phase should be adjusted in order to make the SBR more efficient in achieving discharge permit requirements.
