About the Integrated Bio-Reactor
The Integrated Bio-Reactor (IBR) is a unique modification of the activated sludge process in which the clarifier is placed within the aeration tank. The above-ground design reduces system footprint and saves on costs associated with excavating and constructing traditional concrete basins.
Composed of aerobic, anaerobic, and clarification zones, the IBR is designed to treat typical municipal wastewater. The operation and maintenance of the IBR is simple, as the system's only moving mechanical parts are the aeration blowers, which drive air into the reactor.
- Bolted-steel structure eliminates need for expensive concrete tanks
- 30-foot high tank walls allow for increased oxygen transfer
- Internal clarifier tank reduces system footprint
- Reduced detention time delivers higher processing rate
- Minimal moving parts means lower power requirement and reduced maintenance

Significant Sludge Reduction
Municipal wastewater treatment plant for 1M inhabitant city:
- High rate sludge production: 55g BOD5 x 1M x 0.55 = 30.25 Tons/day
- Extended aeration = 24.75 Tons/day
- Integrated Bio-Reactor = 4.95 Tons/day
Sludge reduction per year: (30.25 - 4.95) x 365 = 9,234.5 Tons/year
Comparitive Energy Consumption
Municipal wastewater treatment plant for 1M inhabitant city:
- High rate aerobic = energy required 5,958 kWh
- Extended aeration = 4,182 kWh
- Integrated Bio-Reactor = 1,895 kWh
Energy reduction per year: (5,958 - 1,895) x 24 x 365 = 35,591 MW/year

Client Testimonial
The 2.65MGD IBR system built at Russky Island, Russia has been fully automated and operational since the end of 2012. Our client was so impressed with the project that he left us with his endorsement and testimonial.
President Dmitry Medvedev Impressed with Russky Island
During his statement at a preparatory meeting for APEC 2012, for President of Russia, Dmitry Medvedev says that the new wastewater treatment facility alone was worth holding the summit at Russky Island.
