Digestate Drying
Drying Digestate from Biogas Plants – Fluidised Bed Fertiliser Advances
Drying digestate from biogas plants has major benefits. In the advanced TEMA Process™ a fluidised bed dryer dries the residual waste after digestion (the solid and fibrous (thick) portion of the digestate slurry). The mixed stream of the thick fraction and the concentrated thin fraction is dewatered to 70-75% Moisture Content. This is followed by […]
