“…One approach is direct monitoring of foulant deposition on the surface of a membrane, which may be achieved through a variety of techniques, including microscopy, laser sensoring, reflectometry, spectroscopy, and 3D imaging [3][4][5][6][7][8][9][10][11][12]. A comprehensive review of various experimental techniques, capabilities and sensitivity specific to membrane protein fouling is provided in [13].…”

“…Different membrane module types can be investigated as long as the investigated membrane area is larger than the sensor surface. UTDR has therefore already been applied to a broad variety of modules, including flat-sheet [86,87,88,89,90,91,92,93,94], tubular [95] hollow fiber [96,97,98,99] and even spiral wound [100,101] membrane modules. Depending on the frequency, some ultrasonic waves are unavoidably attenuated by the module housing before they arrive at the interface of interest.…”

“…Depending on the frequency, some ultrasonic waves are unavoidably attenuated by the module housing before they arrive at the interface of interest. The penetration at low frequencies is much greater than that at higher frequencies, however, the resolution is greater at higher frequencies, requiring a trade-off between the attenuation and the resolution of the acoustic waves [91].…”

Pressure-driven membrane processes are often used for the separation and purification of organic compounds originating from biomass. However, membrane fouling remains a challenge as these biobased streams have a very complex composition and comprise a high fouling tendency. Conventional, the fouling is monitored based on either a decrease in flux or an increase in pressure over time. Those conventional techniques provide no information on the location, composition or amount of fouling. As fouling is often cumulative, it will be detected as a loss of performance. Once fouling becomes irreversible, it is often not possible to clean the membrane without chemicals and the filtration/separation process has to be stopped eventually. In situ real-time monitoring of membrane fouling could provide dynamic information on the development of fouling, allowing optimization of the process. This paper reviews the state of the art in in situ monitoring techniques that could be applied to membrane processes in the biotechnology, biorefinery and food sectors and briefly reflects on the current awareness of in situ monitoring techniques among experienced industrial users of membrane processes. The physical principles as well as the strengths and weaknesses are addressed, and potentially, promising techniques are identified.

“…Even though ingenious experiments have been designed and performed to investigate the concentration polarization and the corresponding fouling problems in membrane filtration, only qualitative or semiquantitative results have been obtained, which are inadequate to gain a complete understanding of the fouling mechanism [12][13][14][15]. During the past decades, numerous theoretical researches have also been *Corresponding author.…”

2015): Numerical investigation of the membrane fouling during microfiltration of semiconductor wastewater, Desalination and Water Treatment, Membrane fouling is a problem of vital importance in microfiltration. A numerical method was used to investigate the membrane fouling phenomenon during microfiltration of semiconductor wastewater. In the numerical model, the concentration-dependent physical properties were considered and a dynamically updating boundary condition was incorporated to deal with the flux variation with fouling resistance. The mechanism of suspension transition from liquid phase to gel phase was adopted to characterize the formation of membrane fouling. With this method, the flow field and the concentration distribution as well as the fouling resistance in the membrane module were obtained. The results revealed the mass transfer character in the concentration boundary layer and its influence on the formation of membrane fouling. The enhancement effect of cross-flow on membrane filtration was analyzed in terms of wall shear rate and dimensionless Peclet number. Agreement between the simulation and the experimental results demonstrated the applicability of this numerical method in evaluating membrane fouling during microfiltration.
