Sequencing Batch Reactors (SBR)

Sequencing batch reactors treat wastewater in a batch treatment process.

Oxygen is bubbled through the wastewater to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD), producing a high-quality effluent with a low turbidity and nitrogen levels capable of meeting Title 22 effluent quality standards. The SBR accomplishes equalization, aeration, and clarification in a timed sequence in a single reactor basin.   By varying the operating strategy; aerobic, anaerobic, or anoxic conditions can be achieved to encourage the growth of desirable micro-organisims.


The OMNIFLO® SBR system is ideally suited for treating 0.01 to 60  million gallons per day (MGD) with a wide range of effluent requirements.  Applications include:

  • Municipal wastewater including Biological Nutrient Removal
  • Water recycle & reuse
  • BOD & COD reduction
  • Industrial Wastewater
    • Food & Beverage
    • Pulp & Paper
    • Petrochemical & Oil refining
    • Chemical/ CPI
    • Landfill/ Leachate applications
    • Textile Industry
