Technical Comparison 

Other companies say that they produce nanobubble, but it is mostly microbubble with a little nanobubble. Through Fawoo’s nanobubble generator, it produce real nanobubble, and those bubbles remain in water for a long time and keep high level of DO(dissolved oxygen).

Structure of FNBG 

Oxygen from the oxygen generator is supplied to the ozone generator, generated ozone(O3) and oxygen(O2) go into a water tank. Ozone(O3) and oxygen(O2) in the water tank go to a motor(M1-Water Pump) that is sucking water from the outside. Water with ozone(O3) and oxygen(O2) from the motor(M1) goes to a motor(M2),
and nanobubbles are generated. Finally, generated nanobubble water is released outside through the water tank.
At the time, ozone(O3) and oxygen(O2) exist inside of nano/microbubbles, and the remaining gas is reused by gathering in the water tank.

'Nanosight – LM10’ from ‘Malvern Panalytical’ in UK

Measure nanoparticles individually and visualize those particles

Particles included in the sample are scattered when the laser is reflected and visualized by light.



Measurement Result 


Use FNBG-200 and change the amount of oxygen injected (4 sets)

Measure DO after generating nanobubble / Measure particle size after 24 hours

Particles included in the sample are smaller than 300㎚ even though DO is changed.

Particles between 50~300㎚ exist in the sample of 1㎖.

Additional Note 

When raw water with DO 6ppm passes though the FNT model, it generates nanobubble water with about DO 60ppm (±10%).

It can produce 6 times more output if you dilute raw water five times in generated nanobubble water(20 ton/day). → (20 ton/day x 6 = 120ton/day, diluted water DO = 15ppm)

In other words, it can generate 400tons of nanobubble water with DO 15ppm with a 40L oxygen tank (120tons/day x 3 days 8 hours= 400 Tons).


[NOTE] Typical water or raw water used in the data refers to tap water in South Korea. Depending on the quality, composition, and temperature of tap water, the levels of oxygen and ozone dissolved in nanobubble water may vary.

Structure of FNBG


Oxygen from the oxygen generator is supplied to the ozone generator, generated ozone(O3) and 
oxygen(O2) go into a water tank. Ozone(O3) and oxygen(O2) in the water tank go to a motor(M1-Water Pump) 
that is sucking water from the outside. Water with ozone(O3) and oxygen(O2) from the motor(M1) goes to a motor(M2), 
and nanobubbles are generated. Finally, generated nanobubble water is released outside through the water tank. 
At the time, ozone(O3) and oxygen(O2) exist inside of nano/microbubbles, and the remaining gas is reused by gathering i
n the water tank.
