Abstract

LA PRESENTE INVENCION ES UN METODO PARA MONITORIZAR EL NIVEL DE ACTIVIDAD MICROBIOLOGICA DE UN SISTEMA DE FLUIDO QUE COMPRENDE LOS SIGUIENTES PASOS. (PASO A) AÑADIR AL SISTEMA UNA CANTIDAD CONOCIDA DE AL MENOS UN REACTIVO BIORREACTIVO DE DESDE ALREDEDOR DE 10 PPB A ALREDEDOR DE 100 PPM. EL REACTIVO BIORREACTIVO SE AÑADE A UN NIVEL PARA PROPORCIONAR UN SISTEMA QUE TENGA UNA CONCENTRACION DEL REACTIVO BIORREACTIVO IGUAL O SUPERIOR A LA CONCENTRACION DE DETECCION MINIMA DE DICHO REACTIVO BIORREACTIVO EN EL SISTEMA. (PASO B) LA CONCENTRACION DEL REACTIVO BIORREACTIVO ES CONTINUAMENTE MEDIDA POR CUALQUIER MEDIO CONOCIDO. (PASO C) LA CONCENTRACION DEL REACTIVO BIORREACTIVO PRESENTE MEDIDA EN (PASO B) ES RESTADA DE LA CONCENTRACION DEL REACTIVO BIORREACTIVO AÑADIDO EN EL (PASO A). LA DIFERENCIA SE UTILIZA PARA CALCULAR EL NIVEL DE CONSUMO DEL REACTIVO BIORREACTIVO. (PASO D) EL NIVEL DE ACTIVIDAD MICROBIOLOGICA EN EL SISTEMA DE FLUIDO SE CALCULA UTILIZANDO EL NIVEL DE CONSUMO DEL REACTIVO BIORREACTIVO.THE PRESENT INVENTION IS A METHOD FOR MONITORING THE LEVEL OF MICROBIOLOGICAL ACTIVITY OF A FLUID SYSTEM THAT INCLUDES THE FOLLOWING STEPS. (STEP A) ADD TO THE SYSTEM A KNOWN AMOUNT OF AT LEAST ONE BIO-REACTIVE REAGENT FROM AROUND 10 PPB TO AROUND 100 PPM. THE BIOREACTIVE REAGENT IS ADDED TO A LEVEL TO PROVIDE A SYSTEM THAT HAS A CONCENTRATION OF THE BIOREACTIVE REAGENT EQUAL OR HIGHER THAN THE CONCENTRATION OF MINIMUM DETECTION OF SUCH BIOREACTIVE REAGENT IN THE SYSTEM. (STEP B) THE CONCENTRATION OF THE BIOREACTIVE REAGENT IS CONTINUOUSLY MEASURED BY ANY KNOWN MEANS. (STEP C) THE CONCENTRATION OF THE PRESENT BIOREACTIVE REAGENT MEASURED IN (STEP B) IS SUBTRACTED FROM THE CONCENTRATION OF THE ADDITIONAL BIOREACTIVE REAGENT IN (STEP A). THE DIFFERENCE IS USED TO CALCULATE THE CONSUMPTION LEVEL OF THE BIOREACTIVE REAGENT. (STEP D) THE LEVEL OF MICROBIOLOGICAL ACTIVITY IN THE FLUID SYSTEM IS CALCULATED USING THE CONSUMPTION LEVEL OF THE BIOREACTIVE REAGENT.
