Abstract

Sludge dewatering process that makes it possible to achieve a high degree of dryness for a limited electricity consumption, comprising a step of chemical conditioning (S1) of the sludge to be dewatered (10) during which a flocculation aid (11b) and a coagulant aid (11a) are added to the sludge (10), and an electro-dewatering step (S4).
