Explore groundbreaking research on air nanobubbles and their revolutionary impact on oxygen transfer in wastewater treatment systems. This comprehensive study reveals how nanobubble technology achieves six times faster dissolved oxygen increases compared to conventional aeration methods, offering significant energy savings and enhanced treatment efficiency. Learn about the experimental results using Acniti's Microstar Nanobubble Generator, which demonstrates improved oxygen mass transfer coefficients and optimal bubble size distribution.
The Oxiti Aerator 100 is a high-capacity industrial air pump designed to feed nanobubble generators in deep-water installations. It delivers 40-100 LPM of clean air at depths up to 6 meters, enabling continuous oxygen dissolution and nanobubble generation. Oil-free and maintenance-free for up to 15,000 hours, it's built for continuous aquaculture, water treatment, and aeration operations.
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.

The wall mounted Turbiti is the multipurpose nanobubble 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.
Ozone is one of the most powerful disinfectants available, but getting it into water efficiently is the challenge. Turbiti Ozone nanobubble mixers use proprietary swirl flow technology to dissolve ozone as ~100 nm bubbles, extending ozone residual and improving treatment performance across a range of water volumes and applications.
Acniti offers dissolved oxygen controllers and handheld monitors designed for nanobubble generators and oxygen generators. The DO controller automates aeration using PLC-based setpoint control, while the Polaris handheld sensor provides portable DO measurement with NFC and Bluetooth. Both target aquaculture, shrimp farming, and high-DO water treatment applications.
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.
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.
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.

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.
Self-cleaning filters prevent pumps from blocking and make aeration more efficient. These pump are also excellent as dewatering filters for drainage of tanks or flooded areas. This video explains the inner-workings of this smart water-filter.
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.

The Oxiti Booster is a compact PSA oxygen generator built for industrial applications that need sustained high pressure. The Mini Booster delivers up to 140 kPa continuously, and the Booster reaches up to 400 kPa - both at up to 8 LPM, rated for 24/7 operation. Built from Japanese components, including Thomas Compressors and Fuji Electric. Not for medical use.
The Oxiti is a heavy-duty industrial oxygen concentrator using PSA technology to deliver 85-96% pure oxygen at various flow rates. Featuring a rugged aluminum chassis and Japanese components, it is engineered for harsh environments in aquaculture, water treatment, and nanobubble applications. Strictly for non-medical industrial use.
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.
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.
Standard venturi injection lets ozone off-gas before it can work. The Turbiti O3 Mount combines venturi injection with turbulent nanobubble mixing to keep ozone dissolved far longer. No pump or external power needed - just connect water in, out, and ozone gas. Available in models 828 and 838, covering 75-400 LPM for greenhouse disinfection, livestock drinking water, and industrial wastewater ozonation.
Choosing the wrong benchtop nanobubble generator derails experimental reproducibility. Gas chemistry, shear profile, and thermal budget all determine whether miniGaLF, Turbiti Fusion, or microStar fits your protocol. This guide breaks down all three systems so your hardware matches your science, not the other way around.
