Sequencing Batch Reactors (SBR Wastewater Systems)

Our bioCYCLETM is one of the most efficient and compact systems in the industry.


What is an SBR system?

bioprocessH2O’s bioCYCLETM Sequencing Batch Reactor (SBR) is a compact system that is used for the treatment of industrial and municipal wastewater. The SBR utilizes a fill-and-draw activated sludge process within a single tank to achieve several biological processes, including aerobic and anoxic treatment.


What can an SBR system be used for?

The bioCYCLE™ SBR may be used for the removal of pollutants including COD, BOD, ammonia, nitrate, and phosphorus. Once the cycles are complete, the treated effluent may be discharged directly into the environment or to the sewer. The operation of the bioCYCLETM SBR process is simplified due to the instrumentation and controls that are included with each system. Each biological and sedimentation process is monitored and can be controlled remotely ensuring efficient treatment through each cycle.

Our bioCYCLETM SBR technology provides a cost-effective, easy to operate solution that is mechanically simple, flexible, and compact. It is able to treat different kinds of effluents such as municipal, brewery, landfill, and dairy wastewaters.

If you’re looking to upgrade an old SBR, bioprocessH2O can provide all the required equipment and expertise to modify your existing treatment basin into a bioFAS™ Moving Bed Biofilm Reactor (MBBR), bioFLOW Membrane Bioreactor (MBR), or bioPULSE Airlift MBR.

There are four main steps to the SBR process.

  1. Charging - The wastewater goes first into the first holding chamber, where the solid substances are filtered. From there, the wastewater is directed into the SBR tank.
  2. Aeration - The biological cleaning by microorganisms now takes place in the SBR tank. Alternating between short aeration and rest phases in a controlled cleaning process. The "activated sludge" can now develop with millions of microorganisms and clean the water.
  3. Rest phase - During the rest phase the live sludge sinks to the bottom of the system. This allows a clearer water zone to form at the top of the SBR tank.
  4. Clear water extraction - The purified wastewater is now fed into a discharge waterway or into an infiltration system. Afterwards, the sludge is fed back from the second tank into the first tank.

Our bioCYCLE SBR technology provides a cost-effective, easy to operate solution that is mechanically simple, flexible, and compact, while requiring minimal maintenance.
