Abstract
A method and plant for recovering phosphate from a biomass material, the biomass material suitably being a waste activated sludge from an upstream wastewater treatment process including a biological P removal process. The method includes an anaerobic digestion stage and steps for recovering independent streams rich in POand Mg, or rich in POand NH, thereby increasing the amount of P recovered and avoiding struvite formation in the anaerobic digester and accessory equipment thereof, such as pipes.
