 / Energy Efficiency  
Based on Fawoo’s model,
 FNBG-600

Output of nanobubble: 600ton/day

Electricity consumption: 5.3㎾/hour

Bubble Size
Smaller than 300㎚ Other companies produce micrometer(㎛) bubbles.
Installation 
/ Maintenance
Optimal space utilization through miniaturization and light weight

Wheel mounting for easy movement Simple electrical connection

Placement of parts by area for easy management

Parallel connectivity to increase output

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.

Performance Test of FNBG 
- Test Model: FNBG-600
- Concentration & Size of Nano Bubble 

Measuring Equipment 


'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

after generating (Measured after removing microbubble completely)


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

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

Half-Life of DO Measurement  

The table below shows a half-life of DO between the amount of dissolved oxygen (DO) in the nanobubble over time and the first day comparison.

Production Cost  

Oxygen consumption cost: Using an oxygen generator 


Power consumption cost: ₩15,260/day 
Power consumption: 5.3㎾ (FNBG-600) 

5.3㎾ X 24hours X ₩120(cost for 1㎾) = ₩15,260  
Total Cost: Oxygen Cost( 0) + Electricity Cost = ₩15,260/day
