An ultrafine bubble generator is a device that mixes water and a gas and produces ultrafine bubbles. Ultrafine bubbles should be smaller than 200 nano meter to be called an ultrafine bubble. Since 200 nano meters is quite large to be called nanoscopic the name nanobubbles is is for this reason not officially used by ISO. The ISO has named nano sized bubbles ultrafine bubbles. The naming convention follows the same names as for particles.
Basically, there are two types of ultrafine bubble generators, first there are gas-water circulation types of ultrafine bubble generators. Second there is a gas-water pressurization-decompression also often referred to as pressurized dissolution type of ultrafine bubble generator. All units are based on one principle or the other or a combination of both. In the gas-water circulation type the gas is introduced into a water vortex and the gas bubbles are formed by breaking the vortex. In the pressurized dissolution method about 5% of gas is under pressure dissolved in water and forms a supersaturated solution. When the water is depressurized the gas escapes from the water and forms ultrafine bubbles. It's like opening a bottle of beer or a can of coke, the drink in the bottle is depressurized and bubbles are formed. The pressure in a beer or coke is to low to form any ultrafine bubbles.
Acniti sells ultrafine bubble generators with the gas-water circulation type, we have branded them the turbiti series. Acniti also sells the pressurized dissolution ultrafine bubble generators which are branded as GaLF. GaLF stands for Gas Liquid Foam.

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.
The turbiti ultrafine bubble generator is a first-class workhorse nanobubble generator. Turbiti has no moving parts so maintenance is minimal, it can be place in the most demanding environments. The nanobubble generator requires a low head pump, so its efficient in energy usage. The Turbiti concept gives you a worry free nanobubble solution generating billions of bubbles for many years.
The miniGaLF is an entry level GaLF model designed for companies, universities, research institutes and individuals that want to learn about ultrafine bubble technology.
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 ultrafine ozone bubble mixer is a nanobubble generator which is specifically designed for the use with ozone. Research with universities has shown, that ozonated ultrafine bubble 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.
High concentration ultrafine bubble generator, producing the highest concentration of bubbles in the industry. Creates billions of nano bubbles in water.
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.
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 ultrafin bubble generator for your research, application development or ultrafine bubble production.
Low cost Ultrafine Bubble Monitoring ALT-9F17 system, to measure reliably the concentration of ultrafine bubbles (nanobubbles) in your water.
Customized GaLF solutions built into your own applications, this is a stainless steel model
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.
The miniGALF is IDEC`s entry level GaLF model designed for first experiences with nano bubble technology. The miniGaLF -Plus enables higher concentration of nano bubbles by multi-passes of water through the miniGaLF.
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.
Washing of surfaces and laundry is one of the promising areas were ultrafine bubbles 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. Ultrafine bubbles can lower the surface tension of water, the large amounts of oxygen molecules in bubbles charge the water negative.

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 miniGaLF is ACNITI`s entry level GaLF model designed for companies, universities, research institutes and individuals that want to learn about Ultrafine bubble technology. In this blog a movie is shown of the connections and the performance to create ultrafine bubble (nanobubbles) with high DO water.
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.
