Foam fractionation is a well-developed technology used to separate surface-active
compounds from solution by exploiting their affinity for the air–water interface. The …

Biosurfactants could potentially outperform traditional surfactants in many applications whilst
being more sustainable to source, manufacture, use and dispose of. However, currently …

Foam fractionation is a separation process in which proteins and other amphipathic species
adsorb to the surface of bubbles. The bubbles are then removed from the solution in the form …

This study models soluble surfactant transport on and within a foam film during a foam
fractionation process. Marangoni flow drives surfactant onto the film, and also surfactant …

The expansion device is the critical component of micro-to-small scale organic Rankine
cycle (ORC) systems, substantially affecting system efficiency and cost. Low isentropic …

This paper shows that the foam drainage characterisation of Stevenson (2006a) provides a
useful basis for the modelling of foam fractionation systems with and without reflux following …

In this research, a continuous multistage ion foam fractionation column with bubble-cap trays
was employed to remove cadmium ions from simulated wastewater having cadmium ions at …

Technological advancement, on the one hand, leads to the enhanced quality of the final
product but on the other hand, generates a good quantity of effluent. The wastewater …

Enrichment in foam fractionation is enhanced by reducing the liquid flux while maintaining
the flux of bubble surfaces. We show that it is possible to do so in a continuous foam …

This study models convective transport of soluble surfactant in a foam fractionation system
with reflux. Owing to reflux, initial surfactant concentration in films is lower than in Plateau …
