Sequence Batch Reactor (AeroSBR)

Sequence batch reactor (SBR) technology is a suspended growth biological treatment process whereby the microorganisms are aerated, settled and the effluent decanted in the same reactor.

In sequence batch reactor technology, wastewater undergoes cycles of aeration, mix, settle and decant. The process degrades soluble organic material and removes nitrogen via the nitrification and denitrification process. Excess bio solids are removed by a waste activated sludge pump.

Aerofloat’s sequence batch reactor technology (AeroSBR) offers an economical solution for companies. The unique design of Aerofloat’s patented SBR system includes aeration lances which can be removed for cleaning while the process is still in operation. This eliminates the need to drain the tank or shut down the SBR system.

The AeroSBR uses Aerofloat’s unique, patent-pending aeration lance design and its unique air locked syphon (AeroALS) decanter to ensure a maintenance friendly plant.

Aerofloat has extensive experience in the biological treatment of wastewater and can offer its AeroSBR patented design, or manufacture conventional SBR systems if larger, more traditional systems are required.

Clarification in Same Reactor

Clarification in Same Reactor

Aerating, settling and decanting in the same reactor overcomes the need for a separate clarifier, and in the case of the MBRs, also prevents frequent membrane cleaning or replacement.

Air Locked Syphon (ALS) Decanter

Unlike conventional SBR units with lowering decanting weirs, the AeroALS decanter can be installed in covered tanks, enabling the AeroSBR to be sealed and vented, preventing any unpleasant odours from escaping.

The AeroSBR is a unique take on traditional sequence batch reactor technology. Using proven principles, the AeroSBR uses Aerofloat’s patent-pending aeration lance design and its unique ALS decanter to provide a cost-effective, maintenance friendly alternative for biological treatment. Aerofloat’s SBR technology is easy to operate, economical and innovative.

Aerofloat’s sequence batch reactor (AeroSBR) is housed in conventional industrial polyethylene tanks. The flowrate of the AeroSBR is predominately dependent on the quality of the incoming feed and the residence time within the reactor.

Aerofloat designs and builds its own proprietary equipment and is able to produce custom solutions. Aerofloat has full design and manufacturing capabilities in-house and can also build traditional SBR units.
