Verfahren zur Bestimmung der Effektivität eines Filters und Filteranordnung zur Durchführung des Verfahrens

摘要

The filter arrangement comprises a filter which is divided into a first compartment which is cross-flown by a first liquid and a second compartment which is cross-flown by a second liquid in an opposite direction. At least one substance, which can pass through a membrane, passes through said membrane. The invention is characterized in that at least one sensor is arranged in the region of the filter and/or in the line upstream from and/or downstream from the filter, whereby said sensor detects the concentration of at least one substance contained in the first liquid and/or second liquid. The method for determining the effectiveness of a filter in a filtering arrangement is characterized in that said concentration is determined on the basis of the concentration values detected by the sensor (s) during the filtering process.
