Abstract

SE DESCRIBE UN APARATO (1) PARA TRATAR UN FLUIDO, EN ESTE CASO AGUA RESIDUAL, QUE COMPRENDE UN CONTENEDOR O TANQUE (2), UNOS MEDIOS (3) PARA SUMINISTRAR EL AGUA EN SECUENCIAS ALTERNAS AL CONTENEDOR, Y UNOS MEDIOS 84) PARA OXIGENAR EL LECHO DE MEDIOS GRANULARES (5) Y OFRECER MEDIOS FILTRO AIREADOS. EL LECHO FILTRO SE AIREA DURANTE LA OPERACION POR AIRE, AIRE OXIGENO-ENRIQUECIDO U OTRO GAS QUE SE INTRODUCE EN O ADYACENTE A LA BASE ( COMO SE OBSERVA) DEL LECHO A TRAVES DE UNOS MEDIOS (4), QUE PUEDEN SER UN COLECTOR PERFORADO, UN DIFUSOR O SIMILAR QUE SE EXTIENDE SOBRE LA SUPERFICIE TOTAL DEL LECHO. TAMBIEN EL LECHO ES UN MEDIO GRANULAR TAL COMO MINERALES NATURALES O UN MEDIO DE ESCORIA DE ALTO HORNO PARA LA SUPERFICIE DE PARTICULAS DISCRETAS A LA CUAL SE UNEN BACTERIAS Y MICROORGANISMOS ( UNA BIOMASA) QUE EFECTUAN EL TRATAMIENTO DEL FLUIDO. EL FLUJO POR LOS MEDIOS (3) DERIVADO DE LAS AGUAS CLOACALES ES CONTRA CORRIENTE AL AIRE, Y ES PARTICULARMENTE UN FLUJO NO NITRIFICADO QUE HA SIDO PREVIAMENTE TRATADO PARA REDUCIR LA BOD ( DEMANDA BIOLOGICA DE OXIGENO) Y LAS CONCENTRACIONES DE SOLIDOS EN SUSPENSION. EL MEDIO (5) TIENE UN PROMEDIO DE TAMAÑO DE PARTICULA DE 2.8-408 MM Y UNA POROSIDAD DE 13.9%. AL LLEVAR A CABO EL PROCESO LA INVERSION PERIODICA DEL FLUJO A TRAVES DEL LECHO FILTRADO MANTIENE EL GRADIENTE DE CONCENTRACION DE MICROORGANISMOS (BIOMASA) SUSTANCIALMENTE UNIFORME COMO CONCENTRACION DESEADA DE MICROORGANISMOS POR TODA LA PROFUNDIDAD DEL LECHO BAJO TODAS LAS CONDICIONES DE OPERACION EN LAS FORMAS ILUSTRADAS. EL APARATO OFRECE UN TRATAMIENTO EFICIENTE DE LAS AGUAS CLOACALES.
