Abstract

The invention relates to a sludge dewatering method making it possible to reach a high level of dryness with a limited use of electrical power. Said method includes: - a step for chemically conditioning (S1) the sludge (10) to be dewatered, during which a flocculation additive (11b) and a coagulation additive (11a) are added to the sludge (10); and - an electro-dewatering step (S4).
