Nanobubbles

Ultrafine bubbles for purification of water in aquaculture, ponds, lakes, horticulture, agriculture and industry. Experiments have shown increased growth rate in agriculture and aquaculture.

Key Advantages Lake Remediation:

• Introduces two forms of gas into the water: dissolved and nanobubbles

• Very high oxygen transfer efficiency (OTE) regardless of water depth: >85%

• Evenly oxygenates the entire water column
• Highest oxygen utilization when compared to all alternatives
• Stable dissolved oxygen levels
• Simple and immediate ramp up or down capability
• Superior water quality and disease prevention
• Breakdown of off-flavor compounds in RAS systems


Key Advantages Industry:

• Scaling Removal
• Improved Heat Transfer
• Evenly Treats The Entire Water Column
• Biofilm Removal
• Antifouling (prevents attachement of new organizmes)
• Reduced Maintenance Costs
• Cleaning Drain Pipes
• Superior water quality and disease prevention
• Better Equipment Performance
• Tasty Water
• Disinfection


Key Advantages Hatcheries:


• Hatchery tank aeration
• Water quality improvement
• Evenly oxygenates the entire water column
• Highest oxygen utilization when compared to all alternatives
• Stable dissolved oxygen levels
• Healthy fish
• Superior water quality and disease prevention
• Breakdown of off-flavor compounds in RAS systems
• Biofilm control
• Increased fish growth rate

• Increased fresh fish storage


Key Advantages Buildings:


• Scaling removal
• Improved heat transfer
• Protects piping with still standing water
• Biofilm removal
• Reduced maintenance costs
• Cleaning drain pipes
• Superior water quality and disease prevention
• Better equipment performance
• Tasty water
• Disinfection

• Cleans water heaters, coolers, evaporators and other euipment

• Increased hygenie by use with handwash, shower and cleaning



ISO 20480-1:2017 Bubble size definition
Microbubbles: Greater than 1 and Less than 100 μm
Fine bubble: Less than 100 μm
Ultrafine bubbles: Less than 1 μm, normally between 100 and 200 nm

Nanobubble is old term for Ultrafine bubbles

Ultrafine bubbles mix with the water and do not rise like microbubbles, the bubbles can be bound to the water for several weeks.

About 1 million Ultrafine bubbles fit inside a microbubble, which forms a surface of 2000 x microbubbles.

Comparison with microbubbles on the left, untreated in the middle and ultrafine bubbles on the right.

Ideal for use in onshore facilities such as hatcheries and smolt facilities, problems such as biofilm and oxygen content are solved, at the same time the water is clear and clean with good well-being for the fish. The entire plant is oxygenated and oxygen is bound to the water for several weeks.

From PLoS ONE 8(6): e65339 Research


Ultrafine bubbles (<200 nm in diameter) have several unique properties such as long lifetime in liquid
owing to its negatively charged surface, and its high gas solubility into the liquid owing to its high
internal pressure. They are used in variety of fields including diagnostic aids and drug delivery,
while there are no reports assessing their effects on the growth of lives. Nanobubbles of air or
oxygen gas were generated using a nanobubble aerator (BUVITAS; Ligaric Company Limited,
Osaka, Japan). Sweetfish (for 3 weeks) and rainbow trout (for 6 weeks) were kept either within air-
ultrafine bubble water or within normal water. Oxygen-ultrafine bubble significantly increased the
dissolved oxygen concentration of water as well as concentration/size of ultrafine bubbles which
were relatively stable for 70 days. Total weight of sweetfish increased from 3.0 to 6.4 kg in normal
water, whereas it increased from 3.0 to 10.2 kg in air-ultrafine bubble water. In addition, total weight of
rainbow trout increased from 50.0 to 129.5 kg in normal water, whereas it increased from 50.0 to
148.0 kg in air-ultrafine bubble water.
