Abstract

L'invention concerne un appareil de filtrage d'effluents, du type de celui décrit dans le brevet principaL Cet appareil comporte plusieurs perfectionnements, en particulier des moyens d'aspiration 15 pour créer une dépression dans le bac il disposé sous le poste de tamisage-filtrage, des moyens d'aspiration 24 agencés au-dessous du poste de décolmatage pour aspirer les gouttelettes en suspension éjectées à travers la toile, et une vis hélicoïdale d'entraînement des boues 29 associée à un cône convergent 32 pour réaliser une déshydratation plus complète des boues recueillies. L'appareil conforme à l'invention exécute une filtration des effluents et une déshydratation des boues, d'efficacité notablement accrue.
