Abstract

L'invention concerne un procédé de traitement des boues résiduaires ou boues organiques similaires, consistant à mélanger un gâteau de boue essorée et un produit d'addition alcalin puis à sécher ce mélange dans des conditions de pasteurisation en utilisant la chaleur de la réaction exothermique avec l'alcali. Le séchage s'effectue par extraction de l'humidité qui s'évapore du mélange via la chaleur exothermique.
