Title
(DE) VERFAHREN ZUR BEARBEITUNG VON BIOSCHLAMM
(EN) A METHOD FOR THE TREATMENT OF BIOSLUDGE
(FR) PROCÉDÉ POUR LE TRAITEMENT DE BOUES BIOLOGIQUES
Abstract
(EN) (57) Abstract The invention relates to a method for the treatment of biosludge, wherein the method comprises mixing biosludge with a bio-based material to form a mixture, wherein the dry matter of the biosludge is at least 0.01 % (w/w) of the total dry matter of the mixture; treating the mixture at a temperature in the range of 60 -295°C under pressure in the pres- ence of steam; and releasing the pres- sure. (Fig. 1)
(FR) La présente invention concerne un procédé pour le traitement de boues biologiques, le procédé comprend le mélange de boue biologique avec un matériau à base biologique pour former un mélange, dans lequel la matière sèche de la boue biologique est au moins 0,01 % (w/w) de la matière sèche totale du mélange ; le traitement du mélange à une température dans la plage de 60 à 295 °C sous pression en présence de vapeur ; et la libération de la pression.
