Abstract

Se revela la deslicuefaccion mejorada del lecho compactado del espesador/clarificador de lecho profundo. Un aparato así comprende una vasija que recibe unalechada de líquido y partículas solidas suspendidas en el líquido. La vasija define una zona deasentamiento libre, una zona de asentamiento obstruídaintermedia, una zona de clarificacion y una zona de compactacion inferior. Se provee un miembro de deslicuefaccion en la vasija, extendiéndose hacia arribaentre por lo menos dos zonas para facilitar el flujo hacia arriba del líquido libre desde una de las zonas inferiores y el asentamiento de las partículas. Uneje de rastrillo giratorio con piquetes están disenados como para liberar líquido intersticial atrapado en una zona inferior. Los piquetes proveen caminos parael líquido se libere generalmente verticalmente. El líquido liberado viaja hacia arriba hasta el miembro de deslicuefaccion y adentro de la zona declarificacion. La zona inferior, liberada del agua intersticial, se aplasta adiconalmente poniéndose más concentrada o densa.The improved dislicuefaction of the compacted bed of the deep bed thickener / clarifier is revealed. Such an apparatus comprises a vessel that receives a slurry of liquid and solid particles suspended in the liquid. The vessel defines a free settlement zone, an intermediate obstructed settlement zone, a clarification zone and a lower compaction zone. A disinfection member is provided in the vessel, extending upwardly between at least two zones to facilitate the upward flow of the free liquid from one of the lower zones and the settlement of the particles. Rotating rake attachment with pickets are designed to release interstitial fluid trapped in a lower area. Pickets provide paths for the liquid to be released generally vertically. The released liquid travels up to the disinfection member and into the declarification zone. The lower zone, released from interstitial water, is additionally crushed by becoming more concentrated or dense.
