Chapter 1: Techniques
1.1 Microbubble Generation: - Venturi Injection: Involves forcing air through a constricted passage, leading to a pressure drop and the creation of microbubbles. - Ultrasonic Cavitation: Utilizes high-frequency sound waves to generate microbubbles through the rapid formation and collapse of tiny gas cavities in a liquid. - Electrolysis: Produces microbubbles through the decomposition of water molecules by passing an electric current. - Membrane Emulsification: Utilizes semi-permeable membranes to create microbubbles by dispersing air in a liquid under pressure.
1.2 Characteristics of Microbubbles: - Size: Typically less than 50 micrometers in diameter. - Surface Tension: Higher than conventional air bubbles. - Lifespan: Longer due to their smaller size and higher surface tension. - Dissolution Rate: Microbubbles dissolve readily in water, releasing dissolved gases more effectively.
