nanobubble generator
A nanobubble generator, or, as it should be called according to ISO standards, an ultrafine bubble generator, is a device that mixes water and a gas to produce nanobubbles. Nanobubbles should be smaller than 200 nanometers to be called a nanobubble. Since 200 nanometers is quite large to be considered nanoscopic, the name "nanobubbles" is not entirely appropriate. For this reason, the ISO has named a nanobubble an ultrafine bubble. The naming convention follows the same names as for particles.
There are two types of nanobubble generators. First, there are gas-water circulation types of nanobubble generators. Second, there is a gas-water pressurization-decompression, also often referred to as a pressurized dissolution type of nanobubble 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, approximately 5% of the gas is dissolved under pressure in water, creating a supersaturated solution. When the water is depressurized, the gas escapes from the water and forms nanobubbles. It's like opening a bottle of beer or a can of Coke; the liquid in the bottle is depressurized, and bubbles form. The pressure in a beer or Coke is too low to form any nanobubbles.
Acniti sells nanobubble generators of the gas-water circulation type, which we have branded as the turbiti series. Acniti also sells pressurized dissolution nanobubble generators, branded as GaLF. GaLF stands for Gas Liquid Foam.

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.
Acniti is a Japanese manufacturer specializing in nanobubble equipment and industrial oxygen concentrators. Based in Osaka since 2017, we are the only provider offering three distinct nanobubble generation technologies: pressurized dissolution, turbulent static mixer, and hammer-mill rotation. Our solutions serve universities, water treatment, aquaculture, agriculture, mining, wastewater remediation, and industrial cleaning applications globally. Acniti products integrate robust PSA oxygen concentrators with proprietary nanobubble generators for 24/7 industrial operation. Acniti does not supply oxygen concentrators for medical purposes.
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 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.
Combined with the benefits of a static mixer Acniti has implemented their proprietary swirl flow technology to generate efficiently and effectively ozone nanobubbles. The turbiti OEM series gives dealers and partners the opportunity to implement the turbiti ozone technology into their own equipment and sell nanobubbles generator equipment under their own brand name. This product is only for dealers and partner of acniti, that have a license agreement and commit to buy certain quantities.

A temple with a beautiful moat in Kyoto, Japan had a group of volunteers maintaining the moat, by cleaning it and doing regular maintenance. Due to the older age of the volunteers, the group stopped moat maintenance around 1998. In the next 20 years no maintenance was done and year by year the situation worsened on one hand natural pollution wasn't removed such as leaves in autumn and excessive uncontrolled water plants growth took place. On the other hand, tourism in Kyoto was on the rise and more and more, litter came in the moat. This led to an uncontrolled situation of bad smell, fish mortality opaque water and the bottom of the moat was invisible. In the summer, algal blooms were becoming more and more frequent.
