Abstract

ESPESADOR DE LODOS CON DISPOSITIVO DE OXIGENACION PARA INSTALACION DEPURADORA DE AGUAS RESIDUALES. LA INSTALACION COMPRENDE UN ESPESADOR DE LODOS (22) QUE PROPORCIONA UNA PARTE SOBRENADANTE (S) Y UN LODO CONCENTRADO (B) EN SU FONDO. UN DISPOSITIVO DE OXIGENACION (56) TOMA MEDIANTE TUBERIAS (50, 51) UNA PARTE DE LODO SOBRENADANTE Y LA OXIGENA EN UN PUESTO DE OXIGENACION VOLVIENDOLA A INTRODUCIR EN EL ESPESADOR (22) MEDIANTE DIFUSORES DE FALDON (62, 63). DE ESTA FORMA SE EVITA EL DESARROLLO DE OLORES NAUSEABUNDOS A LA VEZ QUE SE GARANTIZA UN AUMENTO DE LA CONCENTRACION DE LOS LODOS.
