What are nanobubbles?
Bubbles in diameter smaller than the wavelength of light are called ultrafine bubbles, and they are too small to see. In general bubble with a diameter smaller than 200 nanometer are called ultrafine bubbles. Ultrafine bubbles have many other remarkable features that ordinary bubbles do not possess. For example, these bubbles can stay in a liquid for a long time, and are electrically charged, and are extra highly pressured as well. These special features of ultrafine bubbles have attracted attention from many industries such as agriculture, wastewater, fisheries, drinking water for animals, food, cosmetics, chemical, medical.

Interested to know why nanobubbles are officially called ultrafine bubbles? In this article we explain the reasons why the ISO technical committee has decided to use the official name ultrafine bubbles instead of nanobubbles.
Nanobubbles are useful in accelerating the metabolism of living organisms, but the mechanism is not yet well understood. In a study, they investigated the production of reactive oxygen species (ROS) by Nano Bubbles and the effect on seed germination. The conclusion of the study was seeds in nanobubble water had a higher germination rate than all those submerged in the different other conventional used solutions.

The Turbiti O2 is the multipurpose ultrafine bubble generator suitable for agriculture, horticulture and fish cultivation sites. Super saturation of oxygen for water day storage tanks in horticulture. Drinking water solutions for chicken, cows, pigs and horses, giving high DO water with ultrafine bubbles to animals with enhance their food digestion more efficiently and results in healthier animals.
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.
Carnation flower growers in Japan use nanobubble irrigation technology against fusarium, withering and dying plants, to improve stem quality, flower size, shoot count, volume of stems and growth speed. In the growing season 2017 / 2018, acniti conducted trials, the test area had irrigation water with billions of ultrafine bubbles of an average size of 110 nm and high DO water with 30 mg/l.
A new innovative way to transport fish while sleeping is almost ready to go onto the market. A combination of CO2 and ultrafine bubbles make this possible.
The custom design ultrafineGalF drinking water, fills the need, for a unit for the food and beverage industry to produce ultrafine bubbles or nanobubbles. The ultrafineGaLF custom design unit has the ability to be Clean in Place. CIP is a method of cleaning the interior surfaces of pipes, vessels, process equipment, filters and associated fittings, without disassembly. The GaLF custom is suitable for use with Ozone, Hydrogen, Oxygen and Nitrogen.
The Turbiti O2 pump skid is the multipurpose ultrafine bubble generator suitable for agriculture, horticulture and fish cultivation sites. Super saturation of oxygen for water day storage tanks in horticulture. Drinking water solutions for chicken, cows, pigs and horses, giving high DO water with ultrafine bubbles to animals with enhance their food digestion more efficiently and results in healthier animals.
Manoa lettuce is a lettuce variety susceptible to tipburn. Tipburn is the drying and dying of leaf tissue along the edges of the leaf. During a test at a grower in Hawaii it was shown that by increasing the DO levels and adding ultrafine bubbles, reduction of tipburn is realized and quality and production improvements are made.
The ozone nanobubble mixer is a nanobubble generator which is specifically designed for the use with ozone. Research with universities has shown, that ozonated nanobubble water, keeps longer its ozone residue in the water than when it is used only with a venturi also the amount of ozone gassing out is reduced.
The turbiti nanobubble generator is a first-class workhorse. Turbiti can be placed in the most demanding environments. The nanobubble generator requires a low head pump, so it's efficient in energy usage. Combined with the benefits of a static mixer, Acniti has implemented their proprietary swirl flow technology to generate efficiently and effectively nanobubbles. The turbiti OEM series gives dealers and partners the opportunity to implement the turbiti into their own equipment. The Turbiti concept gives you a worry free nanobubble solution.
Large volume submersible ultrafine bubble generator in combination with a dissolved oxygen generator, for aerating effectively lakes, horticulture, fishponds and shrimp cultivation. Aeration is for many biological processes very important the Acniti submersible unit guarantees high DO values for ideal biological activities creating an optimal environment for high production output.
The miniGaLF is an entry level GaLF model designed for companies, universities, research institutes and individuals that want to learn about ultrafine bubble technology.
High concentration nanobubble generator, producing the highest concentration of bubbles in the industry. Creates billions of nanobubbles in water.
Standard ultrafine GaLF developing optimum measuring and analyzing technologies
Washing of surfaces and laundry is one of the promising areas were nanobubbles can make a difference in the application. Reducing the amount of detergent, has a positive effect by reducing pollution, washing laundry without detergent, would greatly benefit the environment. Nanobubbles can lower the surface tension of water, the large amounts of oxygen molecules in bubbles charge the water negative.
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.
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.
Nanobubbles 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.
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.
Nanobubbles can be measured by the same technology as measuring small particles. You can measure bubbles by camera (count pixel size) or laser (count blackout time), also as a simple method to know number index, you can refer information of turbidity. When you measure UFB, most common way is to analyze Brownian Motion.

Algae blooms are often a reason to start pond remediation. Probiotics in combination with ultra-fine bubbles can increase the efficiency of the wastewater treatment process. Acniti supplies probiotics in tablet form an easy and safe way to dose and apply the beneficial bacteria.
Bubbles are all around us, in our foods, beer, pop drinks bread and cheese, but also in the bricks of our house. Bubbles are gas-filled cavities in water, the lifetime of a bubble is short at most a few minutes, only ultra-fine bubbles are stable for longer periods like months, that is making them very special and that enables us to change the properties of water.
