Abstract

UN METODO Y APARATO PARA TRATAR FANGOS DE AGUAS RESIDUALES LIQUIDOS, DESPUES DE SU GENERACION Y SEPARACION DEL LIQUIDO DE AGUAS RESIDUALES, IMPLICA EL IMPULSO DE UNA PLURALIDAD DE CORRIENTES SEPARADAS DE FANGO VIA, POR EJEMPLO, UN ROTOR (37), E IMPULSANDO DESPUES EL IMPACTO DE PARTICULAS DE FANGO Y CELULAS MICROBIALES CONTENIDAS EN LAS CORRIENTES IMPULSADAS DE FANGO CONTRA UNA SUPERFICIE DE CONTACTO TAL COMO UN ESTATOR (59), PARA RECIRCULACION DEL FANGO A LO LARGO DE UNOS PASOS (62) Y (64) TOROIDALES, Y MEDIANTE ELLO FRAGMENTAR LAS PARTICULAS EN PARTICULAS DE TAMAÑO MENOR, Y ROMPER SEPARADAMENTE LAS CELULAS ORGANICAS. COMO RESULTADO DE TAL PROCESO DE FRAGMENTACION, EL AGUA SITUADA EN LOS POROS DE LAS PARTICULAS DE FANGO SE LIBERA, REFORZANDO ASI UN PROCESO POSTERIOR DE DESHIDRATACION REALIZADO SOBRE EL FANGO. LA DESTRUCCION DE LAS CELULAS PERMITE UN PROCESO DE ABSORCION POSTERIOR DE SOLIDOS, PARA TRABAJAR MAS EFICAZMENTE, EN TANTO QUE PERMITE TAMBIEN UNA CONVERSION MAS COMPLETA PARA DISOLVER AZUCARES, PROTEINAS Y BIOXIDO DE CARBONO.
