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.

Oxygen plays an important role in plant respiration, which causes energy production and plant growth. Increasing the percentage of oxygen in water improves the root structure and the activity of useful microbes in the rhizosphere. Naturally, an effective and practical system can increase productivity by improving the quality of irrigation water and increasing dissolved oxygen in irrigation water. Acniti oxygen concentrator and Acniti turbiti O3 are very effective supplements for irrigation of agricultural fields and at the same time improve water quality and increase dissolved oxygen (DO) and ozone in irrigation water. To determine the role of oxygen and ozone nanobubbles in the growth of lettuce, an experimental research was conducted. Research showed that by using Acniti nanobubbles generators, will increase the level of dissolved oxygen in water, and makes the roots of lettuce grow more and its weight increases significantly.
Water is one of the fundamental components of life. A large part of living cells is made up of water. Birds need twice as much water as the food they eat. To satisfy the need for water in poultry and birds, you must make water freely available to them. Note that the unavailability and limitation of water consumed by poultry slows down their growth. The water used in poultry feeding should not contain parasites, bacteria, pollution or chemicals, and fresh and clean drinking water must be provided. Bacterial agents are one of the most common water-borne infections. Drinking contaminated and untreated water can cause huge losses in the poultry industry. Using chemicals and antibiotics to disinfect drinking water can cause health problems and drug resistance in chickens. In the last decade, researchers have tried to find a suitable alternative to disinfect and improve the quality of drinking water for farm animals, especially chickens. One of the most available and best options is oxygen-nanobubbles water. By providing oxygen- nanobubbles water, the growth and development of chickens increases, and on the other hand, it enhances their resistance against microbial infections. In this article, we evaluate the benefits of oxygen-nanobubbles water in the poultry industry.

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.

When you measure UFB, most common way is to analyze Brownian Motion.
Acniti partner Foreport in Taiwan conducted a vegetables young plant cultivation trial, irrigating with oxygen nanobubbles. The nanobubble irrigation water had a DO of 20 ppm versus the regular irrigation water which had 6.8 ppm.
