Abstract

PROCEDIMIENTO Y APARATO PARA ESPESAR UN LODO DIGERIDO.CONSISTE EN APORTAR LODO DIGERIDO QUE SE TRATA DE ESPESAR Y HACER PASAR UN GAS COMO AIRE A TRAVES DEL LODO DIGERIDO A UNA INTENSIDAD DE MAS DE 0,1 A 5 DE GAS POR 1 DE LODO, SOBRE LA BASE DE VOLUMEN, POR HORA. EL APARATO CONSTA DE UN DEPOSITO (1) SECUNDARIO DIGESTOR QUE PRESENTA UNA PLANTA CIRCULAR CON FONDO INCLINADO, UNA PARED LATERAL Y UN EXTREMO SUPERIOR ABIERTO; UN TUBO DE ALIMENTACION (2) PARA EL LODO DIGERIDO SITUADO PERMANENTEMENTE A LO LARGO DEL FONDO; Y UNA SERIE DE TUBOS DE ALIMENTACION (3) PARA EL GAS QUE SE PROYECTA A TRAVES DE LA PARED LATERAL EN DONDE EL LODO DIGERIDO PASA A TRAVES DEL DEPOSITO (1) DESDE EL TUBO (2) Y ES AIREADO POR EL PASO DEL AIRE A TODO EL VOLUMEN DEL LODO (4) DESDE LOS TUBOS (3).
