摘要：
A method of determining a state of biofouling of a membrane is provided. The membrane is contained within a flow cell and the flow cell has an outer surface coupled to a tranducer, The method comprises introducing inorganic particles into the flow cell such that the inorganic particles form a part of a top surface of a foulant layer on the membrane. The transducer then emits acoustic waves towards the membrane and an acoustic signature of reflected sound waves are detected. A state of biofouling of the membrane is determined based on the detected acoustic signature. A method and an apparatus are also provided for determining a state of biofouling in commercial membrane modules such as spiral wounded membrane modules.
