Abstract:
The present invention provides a method for recovery of phosphate, in the form of magnesium ammonium phosphate (MAP), from a process for treating a biomass material which process comprises a digestion step performed in a digestion tank and includes a pre-treatment step employing a thermal hydrolysis, characterised in that a magnesium source is added to the material in the process flow before said flow enters the digestion tank, and phosphate is recovered as MAP as an integral part of a solid or semi-solid digestate product from the digestion tank.

Claim (Index 12):
A biomass treatment plant for production of biogas, said biomass treatment plant including:\n at least one biomass pre-treatment reactor ( 2 ) having an biomass material inlet for feeding untreated biomass material ( 1 ) and having a pre-treated biomass material outlet; at least one digestion tank ( 3 ) having a pre-treated biomass material inlet connected to said pre-treated biomass material outlet and having a biogas outlet ( 9 ) and at least one digestate product outlet ( 5 ) for the digestate product including as an integral part recovered magnesium ammonium phosphate (MAP); a carbon dioxide separation device ( 10 ) having a biogas inlet connected to said biogas outlet ( 9 ) and having a carbon dioxide outlet ( 13 ) and a carbon dioxide reduced biogas outlet ( 11 ); the at least one biomass pre-treatment reactor ( 2 ) being provided with a steam inlet connected to a steam source, and the at least one biomass pre-treatment reactor ( 2 ) being adapted to perform thermal hydrolysis at a temperature of 140-220\u00b0 C., at saturation pressure; and the at least one digestion tank ( 3 ) being adapted to subject the pre-treated biomass material to an anaerobic digestion at a pH in a range of 7.5 to 8.5 thereby providing a digestate; characterised in that:\n a magnesium ion source inlet is arranged to add a magnesium ion source ( 4 ) to the biomass before introduction of the pre-treated biomass into the biomass digestion tank ( 3 ); and \n in that the carbon dioxide reduced biogas outlet ( 11 ) of the carbon dioxide separation device ( 10 ) is connected to a produced biogas outlet ( 14 ) of the biomass treatment plant and is connected to a carbon dioxide reduced biogas inlet ( 12 ) of the digestion tank ( 3 ) for partial re-introduction of obtained carbon dioxide reduced biogas to the digestion tank.
