Title (EN) METHOD AND APPARATUS FOR SKIMMING FLOATED SLUDGE
(FR) PROCÉDÉ ET APPAREIL D'ÉLIMINATION DE BOUE FLOTTANTE
Abstract:
(EN) A method and device for separating floated matter such as sludge located near the surface of a fluid body is contemplated that employs pneumatic force to separate the floated matter. The contemplated device employs pneumatic force for lifting and blowing the floated matter into an inlet channel. The device is configured to provide substantially uniform airflow across the inlet channel. The inlet channel of the device may also include an adjustable section which allows airflow velocity along the channel to be controlled in a periodic fashion.
(FR) La présente invention concerne un procédé et un dispositif de séparation de matière flottante telle qu'une boue à la surface d'un corps fluide qui utilise la force pneumatique pour séparer la matière flottante. Le dispositif de l'invention utilise la force pneumatique pour lever et souffler la matière flottante dans un canal d'amenée. Le dispositif est conçu pour donner un flux d'air sensiblement uniforme dans le canal d'amenée. Le canal d'amenée du dispositif peut également comprendre une section réglable qui permet le contrôle de la vitesse du flux d'air dans le canal de manière périodique.
