1. A method of operation of a system comprising a membrane filtration system, the method comprising:
measuring, by a flow sensor, a flow rate of a permeate fluid flowing through a filter of the membrane filtration system;
receiving, by a control unit, a signal indicative of the measured flow rate of the permeate fluid;
determining, by the control unit, a first flux rate of the filter based on the measured flow rate signal of the permeate fluid;
comparing, by the control unit, the first flux rate with a first predetermined flux rate;
operating the membrane filtration system, by the control unit, in a normal filtration mode in response to the first flux rate being greater than or equal to the first predetermined flux rate;
operating the membrane filtration system, by the control unit, in (i) a modified filtration mode or (ii) a cleaning mode in response to the first flux rate being less than the first predetermined flux rate, wherein the cleaning mode of the membrane filtration system is further based on a determined normalized water permeability value of the filter; and
resetting the first predetermined flux rate in accordance with a change in transmembrane pressure (TMP) when the filter is operated over a number of cycles until the determined normalized water permeability value of the filter is less than a predetermined percentage of a predetermined base value of the filter.
