Challenge

In 2015, a major refurbishment was carried out at the Flag Fen sewage treatment works (STW) by Skanska Kvaerner, as part of the AMP 5 programme with Anglian Water.

The main project involved the refurbishment of two of the existing aeration lanes. This required the complete closure of the lanes for the cleaning of the diffusers.

As the work was to take place over a number of months, the two operating aeration lanes required additional oxygen in order to cope with the works’ flow.

Work done

Aquasystems International NV provided 1 x 110kW, 2 x 45kW and 2 x 37kW Aqua Turbo floating aerators TYPE AER-AS from their extensive hire fleet. The five units were installed in 2015, together with generators, starters and cabling. All the aerators were installed in situ and commissioned within a few days without any disruption to the existing plant.

Outcome

The aerators were run almost continuously to support and enhance the performance of the existing activated sludge plant. Additionally, the amount of oxygen provided by the aerators ensured that de-nitrification was minimised, thus reducing the risk of rising sludge in the settlement tanks.

Vernon Giblet of Skanska Kvaerner commented that the “all parties involved are extremely pleased with the performance of Aqua Turbo Floating Aerators during this extensive refurbishment programme at The Flag Fen works. The works has met its consent due to the additional aeration capacity provided by Aquasystems International NV”.
