AquaStar Surface Aerator
Description
The AquaStar is the culmination of an intense three-year research and development effort. Combined with decades of field experience and ongoing innovation, the AquaStar has been optimised for diverse conditions. Particular attention has been devoted to making the AquaStar effective and highly efficient over a wide range of power intensities. It is suitable for high rate processes as well as low rate applications. Extensive field testing has provided our firm with unrivalled experience and data on oxygen transfer efficiencies in climates ranging from the tropics to alpine.
Our in-house manufacturing capability has ensured the design is optimised to deliver reliable long-term performance. Sophisticated strain gauge testing has been employed to ensure that the AquaStar delivers robust long term performance despite arduous field conditions. Many installations have remained in service for over 25 years.
Aquatec Maxcon has manufactured and installed in excess of 400 AquaStar aerators since developing and patenting the design in 1991. Key installation include 89 qty AquaStar 30kW floating aerators at Melbourne Water Werribee Treatment Complex, 33 qty AquaStar 37kW and 24 qty AquaStar 15kW floating aerators at Versova - Mumbai, India and 16 qty AquaStar 60kW floating aerators at Sydney Water West Camden STP.
Design
The AquaStar vertical shaft surface aerator is available in a fixed bridge or floating configuration. Both configurations provide suitable access for maintenance and inspection. The floating configuration has a wide footprint and a low centre of gravity ensuring a stable and safe work platform capable of safely carrying all operational and service loads.
Design Advantages
- The AquaStar impeller has a unique patented design to optimise mixing rates and deliver superior oxygen transfer efficiency
- Suitable for applications ranging from high power and high aeration intensity to low power and low aeration intensity applications such as lagoons
- The folded impeller blade profile prevents ragging or fouling, even when used with unscreened wastewater
- Tip speeds of the impeller are less than 7m/s inhibiting shearing of fragile activated sludge flocs
- Reliable with minimal maintenance and low long term operation costs
Applications
- Treatment of raw sewage
- Activated sludge systems
- Intermittent aeration systems
- Oxidation ditches
- Industrial wastewater
- Chemical oxidation
- Gas stripping
- Open water aeration
- Fish farms
