Spotted: The Los Angeles-based company Moleaer has developed industrial-scale nanobubble systems for chemical-free water treatment. The company has just secured $9 million (€7.56 million) in funding for their patented nanobubble technology. With the new fund, Moleaer says that they plan to support more sustainable food production, improved water purification and a greater diversity of natural resources. 

According to Moleaer, the technology works by injecting billions of nano-sized gas bubbles into liquid. With a width of 70-120 nanometers (2500 times smaller than a grain of salt), nanobubbles are extremely efficient in improving water quality, enhancing water treatment processes, and increasing productivity in industrial and agricultural applications due to their size and structure. 

The funding round was led by S2G Ventures’ Oceans and Seafood Fund and joined by ADM Capital’s Cibus Enterprise Fund and Energy Innovation Capital. Moleaer is amongst the first to receive financing from the recently established Oceans and Seafood Fund, which is dedicated to developing sustainable solutions to support the seafood industry. 

With the new financing, Moleaer plans to grow its global commercial and production operations, enhance the research and development of new nanobubble applications, and provide new service offerings — such as equipment and wands.  

According to UCLA professor Michael Stenstrom, its unique nanobubble technology delivers the highest confirmed oxygen transfer rate in the aeration and gas-to-liquid transfer sector – with an efficiency of over 85 per cent per foot of water. This high oxygen transfer rate, according to Moleaer, boosts the efficiency of industrial operations ranging from food production to water treatment and resource recovery.  

So far, the company’s nanobubbles have succeeded in boosting berry size by 14 per cent and salmon biomass by 22 per cent.The technique was also found to improve agricultural production by increasing irrigation water quality, resulting in a 50 per cent reduction in crop loss due to disease. Moleaer is also collaborating with NASA to grow crops in space.
