The Aerofloat Solution
Wastewater and sewage generated from the site’s office and facility buildings required a robust and flexible system that could adapt to the daily fluctuations in flow rates. Nearly half of the minimum 180 occupants were using the site for showers during the peak flow times, with that number expected to grow by half again in the near future. Aerofloat therefore recommended its innovative, adaptable biological system to tackle the client’s wastewater and sewage.
Aerofloat designed its biological wastewater treatment solution using Sequence Batch Reactor (AeroSBR) technology, incorporating Air-Locked Syphon decanters and patented aeration lances that ensured minimal operational downtime.
Its SBR technology enabled suspended growth biological treatment process whereby the microorganisms in the wastewater can be aerated, settled and the treated clear effluent decanted in the same reactor, overcoming the need for a separate clarifier.
The sewage treatment plant was designed to treat a future daily flow of 15.6m3/day and ensure effective treatment of the biochemical oxygen demand (BOD) and ammonia levels in the wastewater.
The AeroSBR was also designed to minimise operational downtime and servicing requirements. Aerofloat’s patented aeration lances were easily removed for cleaning even while the system was in use – saving local staff on system maintenance time.
