Design engineering is at the heart of what Aerofloat does. Watch to see Aerofloat’s unique process configuration for Aerofloat’s sewage treatment plant design at University of Queensland. The unique approach allows us to use the anoxic reactor also as a balancing tank, instead of requiring two separate tanks. This is achieved by pumping forward from the anoxic zone to the aerobic zone, which is different to conventional activated sludge plants which pump recycled activated sludge back from the aerobic zone to the anoxic zone. This process configuration allows us to minimise the footprint of the site while ensuring that diurnal peak flows can be attenuated and treated throughout the day.

Can you tell us about some of the unique things that we put into this design at this sewage treatment plant?
We were able to meet UQ’s flow balancing requirements while minimising the number of tanks on site by using this anoxic tank also as a flow balancing tank, and we’re able to do this by pumping forward from the anoxic zone to the aerobic Zone, which is a unique feature of our process design as most plants have a full anoxic tank which overflows to the aerobic Zone and then recycled activated sludge is pumped backwards. This gives us the unique advantage that we have an optic tank and a balance tank in the same tank, which minimises the footprint of the site.
