Context

Yorkshire Water carried out a major refurbishment of two of the existing aeration lanes at the Mitchell Laithe STW works, as part of the AMP 7 programme.

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

Product supplied

Aquasystems International NV provided four 55kW AER-AS Aqua Turbo floating aerators from its extensive hire fleet. The units were installed together with electrical control panels and cabling, all provided by Aquasystems.

Outcome

The aerators were used to support the existing activated sludge plant and the units have 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 Aqua Turbo floating aerators during this extensive refurbishment programme at the Mitchell Laithe treatment works.

The works met consent due to the additional aeration capacity provided by Aquasystems International NV.
