The invention comprises a method of treating sludges which includes the steps of applying an electric field to the sludge to effect dewatering prior to further dewatering of the sludge. Typically the sludge comprises dilute phase sludge, and the electric field is a DC electric field. The pH of the sludge may be adjusted to between substantially 5 and substantially 6 prior to applying the electric field.
L'invention porte sur un procédé de traitement de boues qui comprend les étapes d'application d'un champ électrique à la boue pour effectuer une déshydratation avant une déshydratation additionnelle de la boue. De façon caractéristique, la boue comprend une boue en phase diluée, et le champ électrique est un champ électrique à courant continu. Le pH de la boue peut être ajusté entre sensiblement 5 et sensiblement 6 avant l'application du champ électrique.
