Gibbs Adsorption & Hydrodynamic Cavitation: The Physical Mechanism of Sub-Micro Flotation
Abstract This paper describes the physical mechanism by which G-Cav™ vortex-induced multistage hydrodynamic cavitation achieves the simultaneous removal of emulsified oils, dissolved surfactants, and hydrophobic contaminants from aqueous streams. Two coupled processes are at work: cavitation-driven emulsion breaking, in which transient implosive pressure events mechanically disrupt stabilised oil-water interfaces; and Gibbs adsorption interfacial scavenging, in […]
