Abstract

A microbubble generator comprising: a first Venturi section (110); a second Venturi section (130); and a mixing section (120) for coupling fluid flow between the first Venturi section and the second Venturi section, wherein the first Venturi section (110) has a first convergent section (112) coupled to a first divergent section (116), providing a first constriction for a flow of liquid through the microbubble generator, and having a gas inlet aperture (118) at or close to the narrowest part of the constriction for drawing gas into a liquid flowing through the first constriction, the second Venturi section (130) has a second convergent section (132) coupled to a second divergent section (136), and providing a second constriction for a flow of liquid through the microbubble generator, and wherein the mixing section (120) couples between the first divergent section (116) and the second convergent section (132).
