  9. Research Omzet.Amersfoort (2010) • 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: • Central digestion + Thermal Hydrolysis • Bio-P en P-recovery • 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

  12. 2013: Procurement • Procurement of Phase 1 and 2 at once • Selection: SH+E • TPH: Stulz – Lysotherm : • P recoverywith Wasstrip and Pearl

  13. ResultProcurement Phase 1 and 2: Energy en Phosphate: Amersfoort Energy neutral 130% Surplus: 2 M kWh/jaar Region 65% self sufficient 70% Heat: dependent on process maximum 40% recovery of total phosphate region 42% Chemical usage: Reduction 50% Sludge: 30% d.w. 31% ROI: 6 years 6,7 jaar
