OMNIFLO® SBR systems: Single-basin equalization, treatment and clarification

Proven performance under demanding conditions

Evoqua's OMNIFLO®​ SBR system using Jet Tech technology includes state-of-the-art equipment and controls to deliver superior performance under the most demanding conditions.

The OMNIFLO SBR is a fill-and-draw, non-steady state activated sludge process in which one or more reactor basins are filled with wastewater during a discrete time period, and then operated in a batch mode. The system accomplishes equalization, aeration, and clarification in a timed sequence in a single reactor basin.

The OMNIFLO SBR system is ideally suited for treating 0.01 MGD to 60 MGD with a wide range of effluent requirements. Applications include:

  • Municipal Wastewater including Biological Nutrient Removal
  • Industrial Wastewater
    • Food & Beverage
    • Pulp & Paper
    • Petrochemical & Oil refining
    • Chemical/ CPI
    • Landfill/ Leachate applications
    • Textile Industry


  • ​Biological Nutrient Removal (BNR)
  • High quality effluent at widely varying flows and loadings   
  • Perfect quiescent settling and solids retention capabilities
  • Choice of aeration/mixing devices
  • No need for redundant clarifiers
  • State-of-the-art controls
  • Retrofit of existing basins

 key benefits

  • Capital, O&M and energy savings—Typically less concrete than continuous flow processes, no MLSS or RAS recycle. Less mechanical equipment typically outside basin and flexible cycle parameters (oxygen provided when needed during cycles).
  • Small footprint—Equalization, biological treatment, and clarification performed in a single basin. Common wall and deep tanks are standard with no need for separate redundant clarifiers.
  • Flexible tank design—Unlimited tank configurations, from steel field-erected package plants to pre-stressed concrete tanks.
  • Safe operation and maintenance—No internal electro-mechanical equipment in the basin requiring maintenance, creating a safer operating environment for treatment plant personnel.
