Installation of the UK’s first two Scum Skimmers has been completed: one on a Final Settlement Tank (FST) at Europe’s largest sewage works, Thames Water Beckton WWTW, and the other on a Primary Settlement Tank (PST) at Severn Trent’s Lichfield STW.

The Scum Skimmer was developed in 1997 and is in use throughout Europe and the rest of the world. Over 1000 installations to date are proof that the Scum Skimmer is the most reliable and effective way to remove floating scum from wastewater tanks and chambers.

The Scum Skimmer has opposing screws which float on the wastewater surface and draw scum into a central hopper. A submersible pump then pumps the scum out of the system via a designated disposal route.

The Scum Skimmer’s floating design ensures that it remains effective with fluctuating water levels of up to 500mm. They can be designed to suit each individual application, including circular and rectangular tanks, and channels of all sizes.

The Scum Skimmer is driven by a small, 0.11 kW drive unit and a maintenance-free, engineered plastic chain – giving powerful scum removal with very low energy usage. Maintenance of the system is minimal with weekly visual checks and a 6-monthly scum pump oil change.
