Problem addressed

Compared to ordinary macro bubbles which rise rapidly and burst at the surface of water, nano bubbles with intrinsic larger gas-liquid interfacial area can stably stay and completely dissolve in water for better functional air or gas dissolution.

  • NAMI's nano bubble generator developed by computation fluid dynamic enhances the dissolution and surface area of different gases by generating nano-sized bubbles. The air-carrying nano bubbles promote the growth of hydroponic plants and fish. 
  • By integrating ozone, the ozone-carrying bubbles possess excellent oxidizing power for water and wastewater treatment. 
  • Combining with ultrasound technology, the nano bubble water can enhance ingredient extraction and the formation of nanoemulsion.
Key impact
  • Excellent gas dissolution
  • Wide applications
  • Low energy consumption
  • Low cost
  • Gold Medal at the “2017 Geneva International Exhibition of Inventions”
