Title
(EN) WASTEWATER SLUDGE PROCESSING SYSTEM
(FR) SYSTÈME DE TRAITEMENT DE BOUES D'EAUX USÉES
Abstract
(EN)
The Wastewater sludge processing system takes sludge directly from the municipal waste water treatment plant and processes it using a low-temperature, low pressure process that has no waste products. The process dries the sludge and separates it into oil that is turned into biodiesel feedstock, cellulose/minerals that are used for heating the process, and water that is reused in the process.
(FR)
L'invention concerne un système de traitement de boues d'eaux usées qui prend les boues directement à partir de l'installation urbaine de traitement des eaux usées et les traite à l'aide d'un procédé basse température, basse pression qui n'a pas de produits de déchets. Le procédé permet de sécher les boues et les sépare en huile qui est transformée en charge d'alimentation biodiesel, cellulose/minéraux qui sont utilisés pour le chauffage du procédé, et de l'eau qui est réutilisée dans le procédé.
