Abstract

UN RECIPIENTE DE TRATAMIENTO (50) CONTIENE UN LECHO FLUIDIZABLE (70) DE MATERIAL SUELTO EN PARTICULAS DE ARENA CORTANTE ADHERIDAS A GRANULOS DE POLIETILENO PARA OFRECER UN HABITAT PARA MICROORGANISMOS EFECTIVO EN EL TRATAMIENTO DE AGUAS RESIDUALES. EL MATERIAL TIENE LA DENSIDAD PREFERIDA LIGERAMENTE MAYOR QUE 1.0 G/CC, UNA SUPERFICIE ESPECIFICA EN EXCESO DE 600 M{SUP,2}/M{SUP,3}, Y UN TAMAÑO DE PARTICULA ENTRE 3 Y 10 MM. EL LECHO Y EL AGUA RESIDUAL SE FLUIDIFICAN Y AIREAN POR BURBUJAS DE AIRE EMITIDAS POR AIREADORES AUTOSELLANTES (71) DISPUESTOS EN LA BASE DEL LECHO Y QUE SE PUEDEN COLOCAR Y QUITAR DESDE MAS ARRIBA DEL NIVEL DEL AGUA. EL MATERIAL SUELTO PUEDE DESCANSAR DIRECTAMENTE EN LA SUPERFICIE DEL AIREADOR.
