Zickert aids London upgrade

摘要

Thames Water is investing in innovative Zickert sludge handling technology from Hydro International in record-breaking contracts totalling £24M at its London sewage works. The Zickert continuous bottom scraping and surface scum removal technology will collect sludge from 53 primary settlement tanks at Beck-ton, Crossness and Mogden sewage works. The projects are designed to increase sewage treatment capacity, improve operating efficiency and reduce odour. In the largest project under way at Beckton STW, 24 existing sedimentation tanks will use new Zickert sludge scrapers, adding to eight existing Primary tanks already converted to the Zickert system. The complete £16.5M installation will cover more than 56,000m2. Thames Water is making the investment in Zickert top and bottom sludge scrapers based on the proven performance of existing installations. Zickert offers significant advantages over conventional sludge scraping technology with lower operating and infrastructure costs.
