Abstract:
1. An apparatus for filtering liquid products, particularly organic liquids, including a filtration bell provided with filtering means including an array of rotating filtering membranes, said filtration bell being connected, on one side, to a feeding circuit adapted to draw the liquid to be filtered from a feeding tank to said filtration bell and, on an other side, to a retentate return circuit, and to a permeate outlet circuit, said apparatus further comprising: a monitoring and control unit; first sensing means connected for signal communication with said monitoring and control unit and suitable for detecting and acquiring at preset time intervals ΔT a value of a first pressure PT second sensing means connected for signal communication with said monitoring and control unit and suitable for detecting and acquiring at preset time intervals ΔT a value of a second pressure PT flow rate detection means in signal communication with said monitoring and control unit and suitable for detecting and acquiring at preset time intervals ΔT a flow rate value FIT in said outlet circuit; first valve means for controlling a flow rate in the permeate outlet circuit, the first valve means being arranged in said permeate outlet circuit downstream of said second sensing means and controlled by said monitoring and control unit, said first valve means being set in an open position during a filtration cycle; said monitoring and control unit including means for comparing and processing the values of said first pressure PT and second valve means for creating a pressure differential are provided in said retentate return circuit, wherein the control unit is configured to adjust said second valve means and said first pressure PT
