Abstract

L'invention porte sur un procédé de déshydratation de boues aqueuses telles que des boues d'épuration. Ce procédé consiste à mélanger un matériau fibreux (par exemple un matériau cellulosique broyé) aux boues tout en les soumettant (a) à une pression ou à une dépression alors qu'elles se trouvent sur un filtre, puis (b) à un champ électrique entraînant le liquide à travers le filtre.
