Small nozzle, big benefits
Introduction to micro-bubble
generating nozzle
Introducing micro-bubbles to public baths and
aquaculture farms easily
Microbubbles of 1 μm to 100 μm are expected to provide visitors with health effects, such as skin beautification and blood flow promotion, in public baths (large-scale public bath & spa facilities, spas, etc.).
Micro-bubbles are also known to eliminate a deficiency of oxygen in water at aquaculture farms, helping the growth of aquatic organisms.
Using our small micro-bubble generating nozzle, you can easily introduce micro-bubbles.
Advantage of the micro-bubble generating nozzles
-
Low cost
Can be introduced at a lower cost than existing bubble generators!
-
High dissolving efficiency
Gas dissolves more easily in water, and thus higher effects can be expected!
-
Small space and easy installation
All you need to do is attach a small nozzle.*
There is no need for large-scale equipment!
* The installation method varies depending on the application.
Low costExamples of components
- Micro-bubble (MB) generating nozzle
- Example 1: Mounting on a general-purpose pump
- Example 2: Gas-liquid mixing system at an aquaculture pond
- Example 3: Carbon dioxide gas supply unit
High dissolving efficiency
A Micro-bubble (MB) generating nozzle self-aspirates gas by utilizing the internal negative pressure generated by the change in the cross-sectional area of the water passage when water is pumped into the generating device, and it makes the gas aspirated by the water flow finer and spurts it out.
* Comparison between dissolved oxygen levels by our MB generating nozzle system and theoretical dissolved oxygen levels at the time of general air blowing (our test results)
| Blown gas | Oxygen |
|---|---|
| Gas blowing flow rate | 0.48NL/min |
| MB generating nozzle size | 25A |
| Water capacity | 81 L |
| Circulating water flow rate | 35L/min |
| Dissolved oxygen meter | DO-31P manufactured by DKK-TOA Corporation |
Furthermore, Micro-bubble (MB) generating nozzles are used to increase the amount of dissolved gas in the water at aquaculture farms and public baths because the following effects can be expected.
- At aquaculture farms
- Promoting growth of aquatic organisms
- In public baths
- Promoting blood circulation and beauty by carbon dioxide baths
Space-saving and easy installation
All you need to do is attach a small nozzle. There is no need for large-scale equipment. Also, the nozzle main unit is small and space-saving.
It can be easily installed as it can be retrofitted to the piping.
