Solution Overview
Problem
Current water purification methods using ozone for disinfection are inefficient, particularly in industrial settings, as they struggle to achieve the required ozone concentration for effective disinfection while minimizing resource usage and costs, especially when handling large volumes of water.
Innovation Solution
A system that combines ozone and oxygen, introduced into a cavitation pump and further processed by a line atomizer, creates ultra-fine bubbles for complete dissolution in water, ensuring effective disinfection and scalability for various water treatment plant sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a bubble diffuser is used to dissolve ozone into water, then ozone can be introduced into water for disinfection, but the dissolution efficiency does not exceed 75%, making the purification expensive and wasteful
Solution Approach 1:
The patent utilizes the phase transition of water from liquid to vapor and back, creating cavitation bubbles that collapse and generate intense local mixing. This phase transition mechanism dramatically enhances ozone dissolution efficiency from below 75% to over 95% by creating turbulent mixing zones where gas-liquid mass transfer is maximized during bubble collapse
Solution Approach 2:
The patent employs mechanical vibration through the cavitation process, where rapid bubble formation and collapse create intense local shear forces and turbulence. This mechanical energy input disrupts the liquid structure and enhances gas dissolution by creating continuous renewal of the liquid-gas interface, thereby improving ozone transfer efficiency while reducing waste
2Loss of energy
If the depth of the water basin is increased to improve ozone dissolution efficiency, then more ozone can dissolve in water, but such an increase may not be commercially viable nor technically practicable in industrial applications
Solution Approach 1:
The patent replaces the mechanical approach of increasing water basin depth with a cavitation-based system that uses controlled bubble dynamics. Instead of relying on gravitational potential energy from deep water columns, the system generates intense mixing through cavitation bubble collapse, achieving superior dissolution efficiency in shallow, commercially viable configurations
Solution Approach 2:
The patent changes the key parameter from water depth to cavitation intensity. By controlling bubble size, formation rate, and collapse energy through adjustable cavitation parameters, the system achieves high ozone dissolution efficiency without requiring increased basin depth, making the system adaptable to various industrial application constraints
3Loss of energy
If higher volumes of water are processed to improve dissolution efficiency, then more ozone can be dissolved, but this makes the purification unnecessarily expensive and wasteful
Solution Approach 1:
The cavitation process creates self-enhancing turbulence where the bubble collapse generates local mixing that automatically draws in more ozone and water into the reaction zone. This self-service mechanism eliminates the need for additional processing volume or external mixing energy input, achieving high dissolution efficiency that scales effectively with water throughput

AI summary
The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump. The ozone and the oxygen are turned into ultra-fine bubbles via cavitation action within the pump, facilitating the dissolution of the oxygen and ozone within the water. The water mixed with the oxygen and the ozone is subsequently supplied to a line atomizer, where the dissolution of the ozone within the mixture is completed. The combined use of the cavitation pump and the line atomizer can lead to a substantially complete dissolution of the supplied ozone within water that needs to be disinfected, allowing to easily achieve the concentration of ozone necessary for water disinfection. Due to this efficiency, the system and method described are highly scalable and suitable for water purification at water purification plants of various sizes.
