Thames Water is investing in sludge treatment equipment from Hydro International at its Beckton sewage treatment works.

The contract is to install Hydro’s Zickert mechanical sludge scraping equipment in two of the sixteen existing primary settlement tanks at the STW in Barking. It follows the successful installation and evaluation of Hydro’s Zickert for a previous upgrade of tanks at Beckton.

As part of the ongoing upgrade at Beckton, Hydro is supplying Zickert longitudinal tank bottom scrapers, scum scrapers and other associated equipment to improve primary sludge settlement performance. As well as the economic advantages and excellent whole life cost, Zickert system scrapers have a low profile which allows enclosure of the tanks should this be required.

Hydro Wastewater Division General Manager Chris Day said: “As we move towards the AMP5 round, the water industry is increasingly looking to refurbishment projects to maximise the performance of its existing installations and achieve the best economic value. Using innovative water treatment technology, such as Zickert, Thames has been able to demonstrate the high performance, minimal maintenance and low lifetime cost of the installation.”
