Abstract: The proposed method includes an initial checking step, during which a pump of a filtering circuit is operated at a given checking operation frequency meanwhile a pump checking operation value is measured, and using the measured data a calculation of the water flow rate when pump operates at a given operation frequency lower than the given checking operation frequency is performed. The pump is then operated at said given operation frequency for a first filtering period of time. When said period is concluded the checking step, at checking frequency, is newly performed obtaining a new checking operation value, and this value is used to calculate a required operation frequency necessary to produce a flow rate equal to the initially calculated flow rate, and the pump is operated at said new calculated operation frequency for a second filtering period of time.
