Sequencing Batch Reactors / Sequential Batch Reactors

Sequencing batch reactors (SBR) or sequential batch reactors are a type of activated sludge process for the treatment of wastewater.

SBR is a high-performance wastewater treatment solution that combines the advantages of batch and continuous flow approaches. This high-performance and versatile technology is compliant with the most stringent discharge standards and provides stable performance despite any flow variations. This high-quality product generates minimal operating costs and is easy to maintain or modify.

This technology is extensively used for treating domestic sewage and industrial effluents.

SBR reactors treat wastewater such as sewage or output from anaerobic digesters or mechanical biological treatment facilities in batches. Oxygen is bubbled through the mixture of wastewater and activated sludge to reduce the organic matter. The treated effluent may be suitable for discharge to surface waters or possibly for use on land.

This Technology is ideal for:

  • Treatment of high load municipal or industrial wastewater and treatment of percolates in warm or cold climates
  • Optimizing operating and equipment costs through a streamlined design
  • Upgrading conventional treatment systems simply and at a minimum cost
  • Meeting requirements respecting effluents, regardless of the prevailing conditions
