1. 6. Phosphorus recovery from sewage sludge fluidized bed gasification processes

   Författare :Thomas Karl Hannl; Marcus Öhman; Matthias Kuba; Nils Skoglund; Flemming Jappe Frandsen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; sewage sludge; agricultural residues; bed material; fluidized bed; feldspar; ash transformation; potassium; phosphorus; ICP-AES MS; SEM; EDS; XRD; thermodynamic equilibrium modeling; Energy Engineering; Energiteknik;

   Sammanfattning : One of the most sustainable pathways of sewage sludge treatment in recent years has been thermal conversion. The benefits of thermal treatment of sewage sludge are the recovery of energy or valuable chemical products, the destruction of harmful organic compounds, the separation of heavy metals from the P-rich coarse ash fraction, and the decreased and sanitized ash volume.
