Rotork electric valve actuators have been used throughout a GBP 55 million new build project procured by West of Scotland Water Authority.

Rotork electric valve actuators have been used throughout a GBP 55 million new build project procured by West of Scotland Water Authority (now Scottish Water) under the Private Finance Initiative to introduce the most up-to-date waste treatment technologies for the benefit of the Greater Glasgow area Central to the scheme - known as the Greater Glasgow Solution - is a new sludge treatment centre, designed and built by Va Tech Wabag UK at Daldowie on behalf of the operations company SMW, a wholly owned Scottish Power company

Capable of handling an annual dry solids load of up to 65kt, the new plant processes sludge from other treatment works in the area, including Shieldhall, where a new pumping station has also been built.

The recently constructed scheme also handles up to 570m3 (tonnes) of liquid effluent per hour, which is treated in aeration/membrane bioreactors, enabling it to be discharged into the River Clyde in an environmentally clean condition.

Nearly 100 Rotork actuators have been installed in the new plant at Daldowie and Shieldhall.

The majority are IQ units operating knife gate and wedge gate valves, together with AQ units operating butterfly and ball valves.
