AquaStar Surface AeratorDescription 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 beenoptimised for diverse conditions. Particular attention has been devoted to making the AquaStareffective and highly efficient over a wide range of power intensities. It is suitable for high rateprocesses as well as low rate applications. Extensive field testing has provided our firm withunrivalled experience and data on oxygen transfer efficiencies in climates ranging from thetropics to alpine. Our in-house manufacturing capability has ensured the design is optimised to deliver reliablelong-term performance. Sophisticated strain gauge testing has been employed to ensure that 1 / 3AquaStar Surface Aeratorthe AquaStar delivers robust long term performance despite arduous field conditions. Manyinstallations have remained in service for over 25 years. Aquatec Maxcon has manufactured and installed in excess of 400 AquaStar aerators sincedeveloping and patenting the design in 1991. Key installation include 89 qty AquaStar 30kWfloating aerators at Melbourne Water Werribee Treatment Complex, 33 qty AquaStar 37kW and24 qty AquaStar 15kW floating aerators at Versova - Mumbai, India and 16 qty AquaStar 60kWfloating aerators at Sydney Water West Camden STP. Design The AquaStar vertical shaft surface aerator is available in a fixed bridge or floatingconfiguration. Both configurations provide suitable access for maintenance and inspection. Thefloating configuration has a wide footprint and a low centre of gravity ensuring a stable and safework 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 deliversuperior oxygen transfer efficiency - Suitable for applications ranging from high power and high aeration intensity to low powerand low aeration intensity applications such as lagoons - The folded impeller blade profile prevents ragging or fouling, even when used withunscreened wastewater - Tip speeds of the impeller are less than 7m/s inhibiting shearing of fragile activated sludgeflocs - Reliable with minimal maintenance and low long term operation costs Technical Please contact Aquatec Maxcon for AquaStar technical information  here .
