Bubbles are gas filled cavities in water. The contact area between bubbles in water filled with tiny bubbles is much larger than water filled with bigger bubbles. The gas pressure inside a small bubble is higher than in a large bubble, therefore the surface tension of a small bubble is higher as well.
There are various technologies to generate nanobubbles (ultrafine bubbles). This article gives an overview of the most used techniques, such as pressurized dissolution, static mixers, and rotational flow.
Great things happen when the world agrees, fine bubbles are an innovative technology, but without proper standards for the industry development, there are obstacles. From 2013 ISO started the creation of an International Standard for fine bubbles popularly know as nanobubbles.
The electrical properties of gas bubbles are important in determining the interaction of nano-bubbles if and when they merge together and how they interact with other materials such as solid particles or oil droplets. Knowledge about this helps application development in for example, protein skimmers, froth flotation, food processing, washing surfaces and purification.
Selecting a nanobubble generator can be a daunting task when you are new to the technology. In the following article we explain the differences of the various units. This helps you to select the best nanobubble generator for your research, application development or ultrafine bubble production.
