Abstract
L'invention concerne la déliquéfaction améliorée du lit compacté d'un appareil d'épaississement/clarification du type lit épais. Un tel appareil comprend un récipient destiné à recevoir une bouillie de particules liquides et solides en suspension dans le liquide. Le récipient définit une zone de décantation libre, une zone intermédiaire de décantation entravée, une zone de clarification supérieure et une zone de compactage inférieure. Le récipient est également pourvu d'un élément de déliquéfaction s'étendant vers le haut entre deux zones au moins, de manière à faciliter d'une part l'écoulement vers le haut du liquide libre à partir de l'une des zones inférieures et d'autre part, la décantation des particules. Un arbre à racloir rotatif pourvu de pics est conçu pour libérer le liquide interstitiel piégé dans une zone inférieure. Les pics créent des passages libérant le liquide généralement à la verticale. Le liquide libéré se déplace vers le haut vers l'élément de déliquéfaction pour atteindre la zone de clarification. La zone inférieure, dont on a éliminé l'eau interstitielle, réduit de volume et devient donc plus concentrée ou plus dense.
