Bio-Wheel
The Bio-Wheel™ is an integrated fixed-film activated sludge (IFAS) rotating aerator.
The Bio-WheelTM is made of a steel frame containing corrugated plastic plates and is integrated into an activated sludge tank. The plastic plates are configured to trap air as the wheel turns and release it beneath the surface of the activated sludge to impart oxygen into the liquid phase.

System Design
The Bio-Wheel™ combines the advantages of activated sludge process with the stability and simplicity of fixed film processes in a single tank. It provides process aeration through rotation of the wheel eliminating the noise and energy loss associated with process blowers.
The Bio-Wheel™ is a green technology allowing the minimization of energy required for activated sludge aeration. The patented corrugated plastic plates are stacked together and then asembled on the wheel frame. During rotation of the Bio-Wheel™, the plates trap air within the wheel before releasing it in the bioreactor.
The Bio-Wheel™ surface area is used for the development of fixed-film bacteria that enhance nutrient removal and increase the average SRT of the system. The biofilm is exposed to environmental air as the wheel turns further enhancing oxygen transfer to the biomass.
