Aqua Turbo® AER-AS floating aerators
In the summer of 2017 Aquasystems International NV was contacted by Saria Ltd with regards to the treatment of wastewater at its Widnes facility.
The treatment process at Widnes WwTW includes wastewater from the plant being fed to two large tanks which are aerated by submersible systems. This increases the temperature of the wastewater, and Saria Ltd wanted to achieve a more efficient processing solution. Aquasystems recommended its floating surface aerators as a way to reduce the temperature of the water and enhance the biological process.
Aquasystems International NV provided one each of its 45kW and 37kW Aqua Turbo® AER-AS floating aerators from its extensive hire fleet. The two units were installed in the summer of 2017, together with starters and cabling. The aerators were installed in situ and commissioned within a few days without any disruption to the existing plant.
The aerators are being used to support the existing activated sludge plant and the units are run continuously to enhance the existing plant. Additionally, there is a benefit from significant temperature reduction in the region of 10-15°C, and an overall performance improvement.
The two units were purchased following an extensive six month trial.
A spokesman for the Secanim Group commented that “all parties involved are extremely pleased with the performance of Aqua Turbo® floating aerators during this extensive testing programme at the Widnes works. The works has met its consent due to the additional aeration capacity provided by Aquasystems International NV."
