Innovative Design Aspects of Advanced Digestion at Beckton and Crossness

Thames Water’s latest two advanced digestion schemes, at Beckton and Crossness in East London, are currently being commissioned. Previously, all sludge generated at these sites had to be either incinerated or treated with lime. Each of these new advanced digestion facilities is designed for to process an average of 100 tDS/d and will provide
significant operating cost savings as well as providing enhanced operational flexibility for sludge treatment.
This paper gives a brief overview of the advanced digestion process, similar at each site, with particular attention paid to innovative aspects of the design, such as the implications for re-using existing digesters, whole life cost analysis for CHP engine selection, and the reasons for selecting Bucher presses to produce digested cake with a
high dry solids content.
The Biosolids conference attracts the most authoritative global experts in the area of biosolids and organic resource handling, treatment and recycling. The programme covers both the latest innovations and updates of existing technologies. Presentations from respected industry experts and newcomers follow the development of technologies and legislation from inception to full-scale installations.
The conference regularly gathers over 200 delegates from all over Europe, many of them return every year both for the technical presentations and fantastic networking opportunities.
Regular conference themes include:
• Thickening and Dewatering
• Modelling Sludge Handling and Utilisation
• Commissioning and Operating Experiences with Thermal Hydrolysis
• Tackling Potential Odour Problems
• Operating Experiences and Potential Problems in Digester Operation
• Ensuring Optimum Energy Recovery from Biogas
• Liquor Treatment and P Removal
• Alternative Products from Sludge
• Enhancing the Value of Biosolids and Digestate
• Pathogens and Pollutants In Digestate
• Sharing Experiences
