Hydrodynamic cavitation, combined with other standard water treatment practices, substantially improves the quality and efficiency of remediation of the most difficult wastewaters.

Cavatition Properties

Brightwater Environmental has harnessed one of the most destructive forces in the natural world—Hydrodynamic Cavitation.

Hydrodynamic Cavitation leverages the physical effects of bubble dynamics to degrade hydrocarbons in contaminated water, offering a promising solution for water purification and environmental protection. This technology is especially valuable in managing produced water from fracking, contributing to more sustainable practices in the energy industry.

Generation of Cavitation: Science, engineering, and technology use cavitation phenomena to accelerate chemical processes, microbial cell rupturing, and mass transfer. 

When kinetic energy is converted to pressure energy using an aperture or a venturi, a fluid mechanics phenomenon known as hydrodynamic cavitation occurs; several other subtypes of hydrodynamic cavitation also exist, including traveling cavitation, fixed cavitation, vortex cavitation, and vibratory cavitation. 
 Hydrodynamic cavitation is capable of extensive industrial applications compared to other cavitational techniques, such as optic, acoustic, and particle, as HC provides ease of scalability, cost-effectiveness, and potentially effective treatment.

Localized Heating: 

This rapid compression of the vapor inside the collapsing bubble leads to a sharp rise in temperature. Studies and experiments show that the temperature inside the collapsing bubble can reach extreme values, often estimated between 5000 K to 10,000 K (approximately 4700°C to 9700°C). These temperatures are comparable to the surface of the sun (which is around 5800 K).

Hydrodynamic cavitation can generate thousands of degrees Kelvin temperatures within the collapsing bubbles.

 The effect is very localized and brief, affecting only the areas immediately around the bubble. This extreme energy release can be both detrimental, as in equipment erosion, and beneficial, as in chemical processing applications.
