Context

Yorkshire Water carried out a major refurbishment at the Lower Brighouse STW works, as part of the AMP 6 programme.

Eight of the existing aeration lanes were refurbished which necessitated the complete closure of each lane for diffuser cleaning or replacement.

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

Product supplied

Aquasystems International NV initially provided eight 55kW AER-AS Aquaturbo floating aerators from their extensive hire fleet. The units were installed together with electrical control panels and cabling, all provided by Aquasystems.

Outcome

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

All parties involved are extremely pleased with the performance of Aquaturbo floating aerators during this extensive refurbishment programme at The Lower Brighouse Sewage Treatment works. The works has met its consent due to the additional aeration capacity provided by Aquasystems International NV.
