What Are Sequencing Batch Reactors?

Sequencing Batch Reactors (SBRs) are a type of activated sludge system that incorporates aeration, clarification, effluent decanting, and sludge wasting into a single vessel. The SBR is operated in batch mode through fill, aerate, settle, and decant/waste phases. The vessel can be a tank, a basin, or even a lagoon. 
  

Applications

SBR systems are well-suited for facilities needing biological treatment in a compact, easy-to-operate system. Industries that can benefit from SBRs include:
   

Bakeries 
Beverage production facilities 
Breweries and Wineries 
Chemical plants 
Dairies 
Food processing plants 
Meat and poultry processing plants 
Pharmaceutical plants 
Pulp and paper mills 
Rendering plants 
Textile mills
