Abstract
A method for assessing a state of fouling of a reverse osmosis system is provided. The method includes deriving a plurality of impedance values from a low frequency region of an electrical impedance spectrum of a reverse osmosis membrane comprised in the reverse osmosis system, and determining a state of fouling of the reverse osmosis system based on the plurality of derived impedance values. Use of the method for in-situ monitoring of fouling on a reverse osmosis membrane, and an apparatus for assessing a state of fouling of a reverse osmosis system are also provided.
