<p>In an embodiment of the present invention a method is disclosed for filtration of a fluid comprising a step of activating the fluid to pass at least through a filter element (13) such as to perform a filtration and, during the filtration, to perform a control cycle comprising following steps of: monitoring a value of a first and a second process parameter of filtration chosen from among: time passed since the start of the control cycle, quantity of fluid which has passed though the filter element (13) since the start of the control cycle, and pressure differential at the heads of the filter element (13); using the monitored values of the first and second process parameter in order to determine the coefficients of a correlation function which sets the first and second process parameter in a single relation; selecting one from the first and second process parameters as a reference parameter and the other as a control parameter; setting a desired value of the reference parameter; applying the desired value and the previously-determined coefficients to the correlation function, in order to estimate a corresponding value of the control value. The results of this estimate can be used to set the optimal conditions in which to carry out the filtering.</p> |
