Abstract

L'invention concerne un procédé selon lequel la structure cellulaire de micro-organismes est détruite sous l'effet d'ultrasons agissant sur des suspensions desdits micro-organismes. Ces suspensions de micro-organismes sont notamment des boues de stations d'épuration biologiques. Ce traitement par ultrasons permet de parvenir à une diminution du volume et de la masse des boues d'épuration à évacuer.
