We will introduce effective ways to utilize micro fine bubbles (MFB). When using micro fine bubbles, it is important to note that microbubbles disappear within 2 to 3 minutes, while nanobubbles remain suspended in water for a long time. Therefore, microbubbles are suitable for showering during baths, but nanobubbles are necessary for agriculture, as well as in the fisheries industry, industrial applications, and water purification. It is recommended to install a buffer tank, temporarily store the water there, and then circulate it with an underwater pump or a surface pump for a while to create nanobubbles before use. Our micro fine bubble generator also has a mixing effect. If pesticides or fertilizers are added to the buffer tank, they will be agitated and converted into nanobubbles. However, since the effectiveness of nanobubbled pesticides or fertilizers may increase, it is necessary to take measures such as reducing the mixing ratio. *For more details, please refer to the PDF materials or feel free to contact us.

Micro-nano bubbles still have many unexplained aspects, but verification in the field is gradually progressing.

In traditional cutting, machining, and drilling processes, oil was primarily used, but in response to environmental issues, it has shifted to a coolant liquid that is 5% oil and 95% water, which is more environmentally friendly. As a result, the smell of oil has been reduced, but problems have arisen, such as water rotting and producing odors during the summer, which is significantly influenced by whether the water in that area is hard or soft. To address this, by micro-nano-bubbling the coolant liquid, it has been confirmed that anaerobic bacteria contained in or generated in the coolant liquid are inactivated, leading to a reduction in foul odors. Additionally, during the micro-bubbling process, it has been confirmed that the mixing effect is enhanced, and the emulsification is sustained. **Effects:** - Reduction of foul odors - Sustained emulsification - Enhanced heat exchange effect - Improved surface accuracy of workpieces - By combining with high-performance filtration systems, the lifespan of blades is extended by about 20%. *For more details, please refer to the PDF document or feel free to contact us.*

Microbubbles are believed to have some activating effects on living organisms, and detailed research is being conducted at universities and specialized institutions. However, until now, it has been challenging to generate microbubbles in cultivation settings such as hydroponics and open-field farming. However, with our microbubbles, you can easily utilize microbubbles and nanobubbles simply by attaching them to a water supply device. It seems that there are already farmers who have succeeded with crops like strawberries, but the specific methods of use are not publicly available due to corporate confidentiality. As a company, we would like to be a bit more open and promote the use of microbubbles and nanobubbles in the future for the cultivation of strawberries and tomatoes, vegetable farming in plant factories, cleaning, transportation, and more. *For more details, please refer to the PDF materials or feel free to contact us.

Microbubbles are bubbles that are 5 to 50 microns in size. In normal conditions, the diameter of water bubbles is about 2 millimeters (2000 microns), so it is difficult to wash away dirt deep within the pores with just regular showers or baths. Furthermore, recently there has been an increase in cosmetics that utilize fine nano-level particles, making it even harder to remove dirt that has entered the pores. This is where microbubbles are expected to play a significant role. In addition, we have answered various questions about microbubbles on our company website, so please take a look at the related links below. *For more details, please refer to the PDF materials or feel free to contact us.

We conducted an evaluation test to determine whether cavitation, which generates microbubbles, actually occurs in our micro-bubble product. A transparent sample was created based on our product. The testing period was from May 1, 2018, to March 31, 2019. As a result of the experiment, it was confirmed that cavitation occurs solely from the pressure of standard tap water, and that approximately 2% of the air contained in the tap water is being converted into micro-nanobubbles. [Summary] ■ Testing period: May 1, 2018 – March 31, 2019 ■ Request details: - Evaluation test to determine whether cavitation occurs in our product to generate microbubbles. ■ Test results: - Cavitation occurs solely from the pressure of standard tap water. - It was confirmed that approximately 2% of the air contained in the tap water is being converted into micro-nanobubbles. *For more details, please refer to the related link page or feel free to contact us.

The evaluation of our products such as ShowerAA for showers, FamilyGG, and WashAA for washing machines, as well as ProGG for stop valves, has been increasing. Consequently, more companies are proposing to install these products at the meter section instead of individually, suggesting a "whole house microbubble system." However, if these are installed too easily at the main water supply, pressure loss can occur, especially when multiple outlets are used simultaneously, which can lead to inconvenience for the homeowners. While it is generally recommended to install them at each individual faucet, we will propose methods for implementing a whole house microbubble system. Please be cautious of sales proposals from those who lack knowledge about pressure loss. **Effects of converting tap water into nanobubbles (ultra-fine bubbles):** - Improved cleaning power - Reduced dirt inside drainage pipes - Suppression of decay (inactivation of anaerobic bacteria) - Promotion of heat exchange - Water savings (approximately 20-40% due to water pressure), etc. These are utilized in various industrial applications such as machine tools, aquaculture, agriculture and forestry, rice washing, brewing, water purification, and cleaning. *For more details, please refer to the PDF materials or contact us.*

Micro-nano bubbles still have many unexplained aspects, but verification in the field is gradually progressing. This time, we will present how to utilize micro-nano bubbles along with some examples. Please also read about the measurement of effects in cutting and grinding using micro-fine bubbles published previously.

In workplaces where coolant is used, the occurrence of factory-specific odors has become an increasing problem. Especially in recent times, when factory tours and evaluations from nearby residents are a concern, and even more so in an era where improvements in the workplace environment for employees are demanded, the generation of odors has become one of the environmental factors that cannot be ignored. In particular, during the hot summer months, the occurrence of odors intensifies, necessitating countermeasures. However, increasing the frequency of coolant replacement or installing air conditioning can be financially challenging. The cause of odor generation in coolant is the proliferation of anaerobic bacteria in the coolant, and as it changes from oil-based to water-soluble, it inevitably becomes more prone to decay. *For detailed content of the article, please refer to the PDF document.

In restaurants, the installation of grease traps is mandatory. Recently, convenience stores have also increased their cooking of fried foods, making the maintenance of grease traps essential. However, the reality is that stubborn grease stains are difficult to clean. Micro-nano bubbles have the property of lifting grease stains from surfaces, and by simply using micro-nano bubble water in kitchens, micro-nano bubbles flow into the grease trap, lifting dirt and making cleaning easier. *For more detailed information, please refer to the PDF document. Feel free to contact us for more details.

Since our company launched the micro-nano bubble generator "WashAA" for washing machines, user interest in the effects of micro-nano bubbles for showerheads, toilets, kitchens, and more has been increasing. In response to such needs, more companies are proposing to install micro-nano bubble generators in the supply pipes after the water meter, aiming to fully convert buildings such as houses and apartments into micro-nano bubble systems. *For detailed information, please refer to the PDF document. For more details, feel free to contact us.*

The circulating water in cooling towers is exposed to the atmosphere, which causes it to decay and grow moss and other organisms. If it is not regularly cleaned with chemicals or other means, its functionality will decline. (This leads to increased electricity costs due to decreased cooling efficiency, as well as rising costs for chemicals and cleaning.) As a countermeasure, one method is to nano-bubble the circulating water, which inactivates anaerobic bacteria that cause decay. Additionally, by ozonating the circulating water into nano-bubbles, it can be purified even more effectively. *For more detailed information, please refer to the PDF document. Feel free to contact us for further inquiries.*

By converting the showerhead into micro-nano bubbles, the drainage pipes become less likely to clog, extending the time before they need to be replaced. However, theft of high-function showerheads is frequently occurring in ryokans, hotels, public baths, sports gyms, saunas, and other facilities. In particular, when high-function micro-nano bubble showerheads are introduced, promoting their effects tends to pique interest, leading to an increase in theft cases. Since shower rooms are private and the shower hose can be easily detached, it is simple to conceal the showerhead in personal belongings and take it outside the facility. Additionally, large public baths cannot have security cameras installed, making it difficult to identify who took the showerhead. *For more detailed information, please refer to the PDF document.

Did you not have doubts about the longevity of drill blades for cutting and perforating using micro-nanobubbles? While micro-nanobubbles have been noted for improving the cutting performance of drills due to their hydrophilicity and reduced surface tension, it turns out that nanobubbles, rather than microbubbles, also have a significant effect. As a result, there seem to be many voices expressing that the effect cannot be felt with generators that have many microbubbles and few nanobubbles (types that draw air from the outside). *For more detailed information, please refer to the PDF document. Feel free to contact us for more details.

Perhaps due to the growing popularity of micro-nano bubble shower heads, there has been an increasing demand for bathtubs to also incorporate micro-nano bubbles.
