Nanobubbles

Nanobobler for rensing av vann i akvakultur, dammer, innsjøer, hortikultur, agrikultur og industri.

Forsøk har vist kraftig økning i vekst rate for fisk.

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



Nanobobler blander seg med vannet og stiger ikke opp som mikrobobler, boblene kan være bundet til vannet i flere uker.

Ca 1 million nanobobler får plass inne i en mikroboble noe som utgjør en overflate på 2000 x mikroboblens.

Sammenligning med mikrobobler til venstre, ubehandlet i midten og nanobobler til høyre.

Ideelt for bruk i landanlegg som klekkerier og smoltanlegg, problemer som biofilm og oksygeninnhold løses, samtidig blir vannet klart og rent med god trivsel for fisken. Hele anlegget blir oksygenert og oksygen bindes til vannet i flere uker.

From PLoS ONE 8(6): e65339 Research


Nanobubbles (<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-
nanobubble water or within normal water. Oxygen-nanobubble significantly increased the
dissolved oxygen concentration of water as well as concentration/size of nanobubbles 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-nanobubble 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-nanobubble water.
