Nanobubble Oxygenation in Recirculating Aquaculture Systems (RAS)

Nanobubbles are miniature gas bubbles that have been shown to have unique physiological benefits for fish. Nanobubbles can also more efficiently catalyze reactions of chemicals, thereby improving the efficiency of recirculating water treatment. Nanobubbles may also enhance activities of microbes and improve biofiltration in RAS. They are an environmentally friendly technique that could possibly reduce the size of the filtration systems resulting in significant potential for design and operational cost reduction.
This project will seek to study the revolutionary potential of nanobubbles at the University of Wisconsin-Stevens Point Northern Aquaculture Demonstration Facility with collaborators:
University of Wisconsin-Sea Grant Institute
UW-Extension
Wisconsin Aquaculture Association
Praxair, Inc.
Gaia Water, Inc
This project is funded by NOAA National Sea Grant College Program. The outcome of this project as well as deliverables will be posted on the project webpage here: www.uwsp.edu/c...

I was surprise to find out about this and more surprised that nanobubble tech has been around for so long. This could be a game changer for aquaculture if the energy analysis comes out to be acceptable. But with renewables, this should not be a problem (just an ROI calculation)

[@BubbleTec]

Microbubble solutions are very good. We look forward to the innovative development of the sustainable aquaculture industry. I'm enjoying the video. Thank you.

Keep up the great work!

This is very interesting and confirms some of the work and research we have already done. Our company manufactures and exports our patented NanoBubblers to several countries across the globe. We will be happy to assist if you are interested to test one of our NanoBubblers as well ?

How is the progress, and will the research data will be provided to general public, if yes when will it be?

[@uw-stevenspointnorthernaqu8491]

The research will be published in a peer reviewed journal and we will notify of project completion and deliverables through our website and newsletter. Please subscribe to receive our newsletter here: www.uwsp.edu/cols-ap/nadf/Pages/Quarterly-Newsletter-.aspx

Hey, just came across this video that was published 2 years ago. Has the research been published?

[@jrmarchesini]

This is so interesting. Any news? are there any results?

[@uw-stevenspointnorthernaqu8491]

Thanks for watching, no we are in the middle of this research. When results are available we will have them on our website, otherwise an easy way to receive updates is our newsletter, you are welcome to sign up for it here: www.uwsp.edu/cols-ap/nadf/Pages/Quarterly-Newsletter-.aspx

The Jesus Lizard, here comes dudley. Very nice

[@ariffiyana2814]

Iam using RAS system also. And i wish i could upgrade with nanobubble. Thx.

[@johncarrigan5530]

What is the method here for generating nannobubble? Is there a significant energy cost?

[@syahiraismail7222]

Nanobubbles generator

[@toddjones5222]

Great intro video. Do you have any research planned to study the efficacy of nanobubbles for reducing the effects of eutrophication?

[@uw-stevenspointnorthernaqu8491]

Thank you for your comment, and no not at the moment, we are focusing mainly for use in RAS at this time.

[@rahmanshaik]

@@uw-stevenspointnorthernaqu8491 Are you using it in filter system also or only in tanks, can you please clarify?

[@uw-stevenspointnorthernaqu8491]

@@rahmanshaik we actually had the nano bubble generator in a sump that fed the fish tanks directly via gravity. Please email our Operations Manager and we can further discuss: [e-mail]

hello, can help me to size my biofilter. the pond is 20m3 of water and the biomass weighs 240 kg and the food has a protein rate of 43% . how to size biological filtration efficiently '?

I have just graduated last year and in a week fist juvenile fish arriving to my modest farm around 5000 fingerlings. I am really concerned about oxygen now the price is four times higher, what is the best solution .... thanks

What about issues of Hyperoxidation??

[@uw-stevenspointnorthernaqu8491]

We are tracking total dissolved gases throughout the project have not seen any major issues so far

Water is not H2O, oxygen is hydrophobic it can not dissolve in water! fish breathe in water as do we with the water vapor in the air.

[@mihaiilie8808]

Its a bad design,non eficient ,high energy consuming if your injecting air into water and especially fresh water wich is less dense than saltwater and bubbles unite faster this reducing the surface area of the bubbles. Overall its a good sistem for oxigenation and water cleaning but you do it wrong ,non efficient.

[@jonosterman2878]

You might want to do some studying up on what nanobubbles are before you make statements like this. You dont seem to understand what they are.
