Nanobubbles
Visualization of invisible nanobubbles in water.
The easiest way to visualize nanobubbles is via a Green Laser beam. The ones you use for a PowerPoint presentation, or some people have them to play with their cats.
Acniti recommends using a Green Laser beam, with a light spectrum of 532 nm and a power usage of 150 mW.

Ozone nanobubbles are attractive for water purification, treatment, and disinfection. ozone nanobubbles have a higher mass transfer rate than ordinary bubbles and there for nanobubbles more efficiently use ozone as a powerful oxidizing agent and sterilizer to kill or inactivate bacteria and viruses.
Concrete is the main part of building materials and it is almost impossible to replace concrete with other natural resources. According to several scientific articles, the application of nanobubbles improved the compressive and tensile strength of concrete. on the other hand, mixture of zeolite, Chekneh pozzolan, and nanobubbles water significantly improve the strength and durability of the concrete, which is a meaningful alternative to cement and mixing water to reduce air pollution, increase concrete performance, and reduce concrete production costs. Nanobubbles technology is the best, cheapest, simplest and safest way to improve the mechanical feature of constructional materials.
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.
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.
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.
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. After 6 weeks results were taken it was concluded that the crop treated with nanobubbles was 25-30% heavier. The nanobubble irrigated crop also had a better developed root system which will lead to less root diseases and better survival rates during hot summers.
Learn how the Complutense University of Madrid uses Acniti nanobubble technology to increase wastewater treatment efficiency and remove emerging contaminants. The research highlights that this technology enhances plants without requiring major infrastructure investments—a significant pain point for municipality and industrial plant managers.
Not all bubbles behave the same. Milli, micro, and nanobubbles each have distinct physical properties that determine how gas transfers in water, how long bubbles persist, and how useful they are in real applications. This guide breaks down bubble size categories, surface area physics, zeta potential, and gas pressure - so you can choose the right bubble technology for your process.

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.
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.
Traditional nanobubble generators rely on pumps and pressure, which wastes energy and stirs up water. The microStar uses patented hammermill rotation - a shaft spinning at 3,400 RPM crushes ozone gas into high-concentration nanobubbles with zero turbulence. Available in three sizes, from lab research to industrial disinfection and seawater treatment.

The Turbiti is a turbulent mixer nanobubble generator built for industrial water treatment, aquaculture, and horticulture. Proprietary swirl flow technology generates nanobubbles with no moving parts and minimal maintenance. The stainless steel housing, built-in one-way gas valve, and particle tolerance up to 2 mm make it a reliable fit for both fresh and saltwater applications, from greenhouse crops to shrimp and salmon cultivation.
Low DO levels in deep reservoirs and ponds stall aquaculture yields and rot root zones in horticulture systems. The Turbiti submersible nanobubble mixer solves this by operating entirely underwater, injecting 100-200nm bubbles directly into the water column for maximum oxygen transfer efficiency. Built from 316L stainless steel, it installs without a pump house and runs on 115 or 230V.
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.
Nanobubble Ozonation is a highly effective water treatment process that utilizes ozone's powerful oxidizing properties to disinfect water, eliminate viruses, bacteria, and other pathogens. It also removes contaminants like iron and manganese, improving taste and odor. This method generates no harmful residuals, making it an eco-friendly choice for safe drinking water preparation.
