Method and Device for Producing a Liquid Which Contains a High Concentration of Very Small Bubbles

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and device for producing a liquid with a very high concentration of extremely small bubbles (nanobubbles or ultrafine bubbles) by circulating the liquid multiple times through a nanobubble generator using pressure differences (not mechanical pumps) to drive the flow. The system includes two reservoirs, a nanobubble generator, and either a pressurized gas unit or movable pistons to create the pressure needed to transfer the liquid without introducing contaminants or causing unwanted heating.

Use CasesContent extracted from patent full text and abstract with AI.

• Medical applications such as ultrasound contrast agents or oxygenation of blood substitutes
• Cleaning and sterilization in the food and beverage industry
• Enhancing gas solubility in liquids for chemical and biological research
• Water treatment (e.g., removal of contaminants, improving aeration)
• Production of highly carbonated beverages
• Pharmaceutical processing where sterile, contaminant-free bubbles are needed

BenefitsContent extracted from patent full text and abstract with AI.

• Achieves higher concentrations of nanobubbles compared to conventional methods
• Avoids contamination since no mechanical pumps or moving parts are required in direct liquid contact
• Minimizes heat generation, preserving gas solubility and liquid properties
• Process can be fully automated and precisely controlled for reproducible results
• Reduces maintenance and equipment wear compared to pump-based systems
• Can utilize various gases and adjust bubble concentrations for different applications

Patent Abstract

The invention relates to a method for producing a liquid which contains a high concentration of very small bubbles. For this purpose, a liquid is provided in a reservoir (5) and is introduced into a second reservoir (6) by a nanobubble generator (7). The method is characterized in that the force for moving the liquid is provided by a pressure difference in the containers, i.e., in particular by a highly pressurized gas or a reduced volume of one of the reservoirs, said gas flowing out of a pressurized gas unit (2) connected to the corresponding reservoir. The liquid can be conducted into the first reservoir again in order to increase the concentration of very small bubbles, and the aforementioned steps can be repeated any number of times. The invention also relates to a device for carrying out the method, having two reservoirs, a nanobubble generator, and a pressurized gas unit which contains a highly pressurized gas or a capability to reduce the volume of the reservoirs.
