With a 0.992 correlation against the NS500, it's a proven NanoSight alternative for industrial process control, automated nanobubble concentration measurement, and energy optimization - bringing accurate ultrafine bubble monitoring out of the lab and into production.
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.
Stagnant water in urban ponds and moats triggers seasonal algal blooms that cause fish mortality, foul odor, and murky water. Acniti solved these problems at Kyoto's 810m Higashi Honganji temple moat using submersible nanobubble aerators paired with a natural probiotics program, raising dissolved oxygen from 4.5 to 9 ppm and clearing the water completely within three months.
Probiotics water treatment with nanobubbles and powerful micro-organisms and bacteria. Efficient micro-organisms working in combination with ultra-fine bubbles
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.
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.
Acniti offers dissolved oxygen controllers and handheld monitors designed for nanobubble generators and oxygen generators.

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.
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.
aquaGaLF is a nanobubble generator for clean water applications including drinking water treatment, aquaculture, and industrial process water. Its hybrid technology produces ultrafine bubbles that raise dissolved oxygen levels and improve water quality. Available in 1.5, 6, and 12 m3/h. Requires particle-free water.
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.

Recirculating aquaculture systems for fish cultivation
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.
Explore groundbreaking research on air nanobubbles and their revolutionary impact on oxygen transfer in wastewater treatment systems.

Learn about the experimental results using Acniti's Microstar Nanobubble Generator, which demonstrates improved oxygen mass transfer coefficients and optimal bubble size distribution.
Benefits for the combination of nanobubbles and probiotics Aquaculture
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.
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.
Low dissolved oxygen (DO) limits biological activity in aquaculture, horticulture, and water treatment. Nanobubble technology solves this by adding two levels of oxygen to water: dissolved O2 and suspended gas cavities. This page covers DO fundamentals, saturation tables, and the role of enhanced aeration.
