Abstract:
Microfiltration device for a fluid filtration process, said microfiltration device having a plurality of microfiltration modules arrayed in parallel rows, having a device for cleansing the microfiltration modules, having a measuring device for recording trans-membrane fluid pressures, and having an analyzer, the analyzer being located and operable for analyzing filtered fluid for one or more of the following components; color, apparent extract, bitterness, pH and alcoholic content of the fluid, characterized in that the analyzer is attached to a control device which is operable to interrupt the filtration process upon the measuring device recording a predetermined trans-membrane pressure which exceeds a value that is determined as optimal based on the analyzer's measurements after the fluid has passed through said microfiltration modules, and thereafter discontinue said fluid filtration process and activate a chemical cleansing process.
