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 …

Inherently occurring foam formation during aerobic fermentation of surface‐active
compounds can be exploited by fractionating the foam. This also serves as the first …

Per-and poly-fluoroalkyl substances (PFAS) are a group of recalcitrant compounds whose
widespread use in a variety of consumer products has led to contamination of groundwater …

Foam fractionation is one solution to recover per-and polyfluoroalkyl substances (PFASs)
from aqueous sources. The separation process is based on the sorption of PFASs to the air …

Biosurfactants are surface-active agents that are produced by a variety of microorganisms
including yeasts, filamentous fungi and bacteria. In this work, we report on the ability of …

In recent years, significant progress has been achieved in the study of aqueous foams.
Having said this, a better understanding of foam physics requires a deeper and profound …

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 …

The quality of foaming products (such as beer and shampoo) and the performance of
industrial processes that harness foam (such as the froth flotation of minerals or the foam …

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

A simple model is presented for foam fractionation. The basis of the model is that the liquid
fraction profile across the foam column is known quasistatically at any instant in time, and …
