Abstract

L'invention concerne un procédé de traitement des eaux usées ou de boues organiques similaires destiné à produire un produit pasteurisé et séché. Le procédé consiste à: séparer la boue en au moins une première partie et une seconde partie; sécher la première partie de sorte qu'elle présente une teneur en matière sèche supérieure à celle de la seconde partie; mélanger la première partie et la seconde partie afin de produire un mélange présentant une teneur en matière sèche intermédiaire entre celle de la première partie et celle de la seconde partie; ajouter une admixtion alcaline au mélange afin de pasteuriser ce dernier et produire ainsi le produit sans nécessité d'effectuer un séchage subséquent par aération.
