Sequencing Batch Reactor (SBR)

The Sequencing Batch Reactor SBR (generic name) is a basin, or a set of basins of waste activated sludge (WAS) working discontinuously, alternating filling and emptying phases.

A settling phase is included to deliver treated water. An SBR is thus both an activated sludge basin and a final clarifier. In most applications five phases are repeated during a cycle: filling, reaction, settling, emptying and idle.

Applications:

  • Small or medium sized plants.
  • High sludge ages (N or N/DN purpose).
  • Cold wastewater.
  • Applications requiring flexibility (e.g. industry).
  • Concentrated waters (e.g. industry)
  • Low SVI.
