How Gibbs Adsorption and Hydrodynamic Cavitation Enable Sub-Micro Flotation
Stable emulsions are one of the hardest problems in industrial water treatment. Oils, fats, surfactants and hydrophobic contaminants can remain suspended in water long after gravity separation should have removed them. The reason is not simply poor settling. It is interfacial chemistry. When surfactants stabilise oil droplets, they reduce the interfacial tension between oil and […]
