Aquasystems supplied and commissioned six Aquaturbo® aerators for wastewater treatment at Southern Water’s Hailsham North Works.

The contract commenced in January 2011 and the units were installed to provide the Hailsham North plant in East Sussex with additional aeration for their existing oxidation ditch.

The existing three horizontal brush type rotors, each with 30kW gearbox-driven motors, did not achieve the demands of the process.

Six 15kW Aquaturbo® floating aerators were installed to upgrade the works and meet the increase in population equivalent demand, attributed to local housing development within Hailsham and the neighbouring areas.

By installing AER-AS floating aerators, the dissolved oxygen levels in the oxidation ditches was increased from 0.2 to upwards of 3-4 mg/l.

The project was led by 4Delivery Ltd and the scheme was part of Southern Water’s Capital Delivery Programme for AMP 5. The Aquaturbo® aerators were delivered on time and within budget and commissioned without problems.

The Aquaturbo® units are direct driven and are easily installed with mooring cables and one electrical connection. There are no gearboxes and maintenance is minimal due to all the wetted parts being manufactured in stainless steel.
