What we will cover
▪ History of ITHP: Thames Water’s Research
▪ Case Study: Site description
▪ Preliminary Results
Second generation: Intermediate THP
When compared to FULL THP…
• Smaller THP plant: 2/3 of Full THP
• Increased gas yield: 500-510m3/tDS Biogas Yield: 500-510 Nm3/tDS Dewatering 30-35%DS
• Higher dewaterability of final cake – Lower digestate volumes: 14.5% less to haulage
• Enhanced according to BAS and Class A product • 40% less steam required in the biosolids line.
• Larger digester volume
