Summary of Project whilst at the UNESCO Centre for Membrane Science and Technology:
AN EXAMINATION OF THE NATURE OF CRITICAL FLUX AND FOULING BY DIRECT OBSERVATION
The concept of critical flux was proposed to explain experimental
observations that below a certain flux, there was no detectable fouling.
Over time this concept has been applied and misapplied to describe a
number of phenomena associated with the onset of critical fouling.
The technique known as Direct Observation Through the Membrane (DOTM) was developed to make use of transparent microfiltration membranes and faciliates the observation of microscopic fouling phenomena at the membrane surface.
In this project the DOTM technique has been used to determine the flux at which particle deposition commences (~critical flux) and to study the subsequent fouling under a range of operating regimes, such as the effects of feed-channel spacers and vertical gas sparging (shown below).
Membranes for this project were kindly provided by Whatman, UK.
