Amersfoort 2 Central Digestion 3 PE dosing 4 Sludge pre- treatment 5 Sludge drying 6 P-recovery 7 CHP study 8 Sudge sale Results: Central digestion + Thermal Pressure Hydrolysis No PE dosing (effluent quality) Bio-P en P-recovery Sludge drying: 75% feasible, but many risc’s CHP, no ORC

10. Project Omzet.Amersfoort (2010) Proposal: Three Phases: 1.Central digestion + Thermal Hydrolysis 2.Bio-P en P-recovery 3.Sludge drying with excess heat LIFE+ subsidy: Realisation innovative aspects (TPH, P, sludge drying) Monitoring results Knowledge sharing

11. Project Omzet.Amersfoort Expected results: – Phase 1: Energy: Amersfoort Energy Neutral Region 65% self sufficient Heat: dependent on process Sludge: 30% d.w. ROI: 6 years – Phase 2: Phosphate: 40% recovery of total phosphate region Chemical usage: Reduction 50% – Phase 3: Sludge drying Sludge: 90% d.w. for 75% of the sludge ROI 7 years
