How are Nanobubbles Created
Nanobubbles can be generated in a few different ways:
Hydrodymic Cavitation
Hydrodynamic Cavitation is a physical phenomenon that occurs when a liquid flows through a constriction - such as a valve, orifice, or venturi - causing the local pressure to drop below the liquid’s vapor pressure, leading to the formation of vapor bubbles. When the liquid subsequently enters a higher-pressure region, these vapor bubbles collapse violently, releasing intense localized energy...
Electrolysis (Electrochemical Method)
Electrolysis is an electrochemical process in which electrical energy is used to drive a non-spontaneous chemical reaction. In simple terms, it splits compounds using electricity - most commonly, water (H₂O) into hydrogen (H₂) and oxygen (O₂) gases...
Pressurized Gas–Liquid Mixing
Pressurized Gas–Liquid Mixing is a process in which gas is dissolved or dispersed into a liquid under elevated pressure to enhance mass transfer, increase solubility, or create micro- or nano-scale bubbles. This technique is commonly used in industries like wastewater treatment, chemical processing, fermentation, and nanobubble generation...
Membrane Sparging / Nanoporous Membranes
Membrane sparging - especially using nanoporous membranes - is an advanced method for generating nanobubbles by forcing gas through ultra-fine membrane pores directly into a liquid. This technique offers high control over bubble size, gas transfer efficiency, and bubble dispersion...
Ultrasound (Acoustic Cavitation)
Ultrasound (Acoustic Cavitation) is a physical phenomenon where high-frequency sound waves (ultrasound) cause the rapid formation, growth, and collapse of microscopic bubbles (cavities) in a liquid. It is a powerful and widely used technique in both industrial and scientific applications.
