Requirement

In early 2019 Aquasystems were contacted by manufacturer A Preston Pet Foods, which required more effective processing of their wastewater being fed from the plant to two tanks.

At the time, the two tanks were aerated by diffuser systems, which increased the temperature of the wastewater. Aquasystems recommended two of its 5.5kW floating surface aerators to reduce the temperature of the water and enhance the biological process.

Solution

The two 5.5kW Aquaturbo TYPE AER-AS floating aerators, together with starters and cabling, were installed towards the end of 2019. The aerators were installed in situ and commissioned within a few days without any disruption to the existing plant.

Outcome

The aerators have been used to support the existing activated sludge plant, and the units have run continuously to enhance the existing plant. In addition, a significant temperature reduction of 10 to 15°C was achieved, and an overall performance improvement obtained.

More units have now been purchased for the new plant.

Testimonial

A spokesperson for the cllient commented that the “all parties involved are extremely pleased with the performance of the Aquaturbo floating aerators at the company's Preston works. The works has met its consent due to the additional aeration capacity provided by Aquasystems International NV”.
