Abstract

Procédé de déshydratation de boues assistée par réactif floculant ledit procédé comprenant une injection de réactif floculant dans les boues et une étape de déshydratation desdites boues caractérisé en ce qu'il comprend une étape préliminaire consistant à mixer lesdites boues dans un mixeur (4) comprenant une chambre cylindrique (4a) munies de pales (4c) montées rotatives sur un axe (4b) tournant à une vitesse de rotation comprise entre 500 tours/min et 4000 tours/min, de façon à les déstructurer et à abattre leur viscosité, et à évacuer les boues provenant dudit mixeur (4) via un réseau (11) vers ladite étape de déshydratation, et en ce qu'il comprend une étape de dépressurisation dudit mixeur (4) et dudit réseau provoquant la lyse par cavitation desdites boues, ladite étape de dépressurisation étant menée pendant une durée d'au moins 0,1 seconde. Installation correspondante.
