Abstract

SE CONOCE LA UTILIZACION DE UN DETECTOR DE CORRIENTE DE FLUJO UNIDIRECCIONAL (SCD) EN UN SISTEMA PARA SUPERVISAR LA CONDICION DE CARGA DE UN FLUIDO DE MUESTRA Y PARA CONTROLAR LA ADICION DE UN AGENTE DE FLOCULACION/COAGULACION. ADEMAS SE SABE DE LA DISPOSICION DEL SCD PARA SUPERVISAR UNA MUESTRA TOMADA DEL SUMINISTRO DE FLUIDO, Y PARA CONECTAR EL SCD EN UN CICLO DE RETROALIMENTACION PARA CONTROLAR DIRECTAMENTE LA DOSIFICACION DEL AGENTE DE FLOCULACION EN EL SUMINISTRO DE MUESTRA. LAS DIFICULTADES SURGEN EN SISTEMAS COMPLEJOS, Y UN CONTROL INADECUADO DE LA DOSIFICACION DE AGENTE DE FLOCULACION RESULTA DEL EFECTO DE QUE EL AJUSTE DE DOSIFICACION ES ECLIPSADO POR OTRAS INFLUENCIAS DE CARGA VARIABLES. LA INVENCION PROPONE UNA SOLUCION EN LA QUE UN CICLO DE RETROALIMENTACION SECUNDARIO QUE INCLUYE LA DOSIFICACION DE UN PRODUCTO QUIMICO (QUE PUEDE SER EL MISMO QUE EL AÑADIDO AL SUMINISTRO PRINCIPAL) EN EL SUMINISTRO DE MUESTRA ES PROVISTO EN TORNO AL PROPIO SCD. DE ESTA FORMA, EL EFECTO CORRECTIVO DE LA DOSIFICACION SECUNDARIA NO ES TRASTORNADO POR LAS OTRAS INFLUENCIAS.
