Birth of the Loop Flow Microbubble Generation Nozzle
The birth of the loop flow microbubble generation nozzle is in the "rice field."
The impetus for developing the loop flow microbubble generation nozzle came from the inspiration I got from observing the phenomenon of stealth bubbles.

![[Case] Purification experiment of salmon farming at 60m depth in the Magellan Strait, Chile.](https://image.mono.ipros.com/public/product/image/c52/2000719282/IPROS63440031661405878955.png?w=280&h=280)
[Case] Purification experiment of salmon farming at 60m depth in the Magellan Strait, Chile.
In the experiment, we are using a "400L/min OK nozzle" to inject fine bubbles into the seabed!
As part of the Magellan Strait seabed purification experiment, we are currently conducting seabed purification experiments in the Magellan Strait of Chile, and we are seeing good results. In Chile, salmon farming has been carried out in the strait's bays for many years, leading to the accumulation of leftover feed and waste on the seabed, which has deteriorated the environment to the point where it is no longer suitable for salmon farming. The project, carried out by the responsible parties in collaboration with aquaculture operators, aims to purify the seabed so that salmon farming can be resumed. Fish farming is taking place in bays around the world, facing similar issues to those in Chile, to varying degrees. Therefore, the results of this experiment are expected to be disseminated globally. Here, we summarize the content of email exchanges regarding the experiments conducted by the responsible parties, and we also provide our own suggestions on the 300m seabed purification method. *For detailed information on the case, please refer to the related links.

[Application Example] Coverage of measures against clams in Lake Shinji.
An example of application where the collaboration of fine bubbles and jet injectors is believed to have been effective.
As a measure against the clams in Lake Shinji, we would like to introduce an application example using the "100L・500L/min OK nozzle." After fishing, we took turns with fellow fishermen to aerate the lake bottom for two hours every day using a jet sprayer to inject fine bubbles. It is believed that the collaboration of fine bubbles and the jet sprayer has been effective. [Overview] ■ In July 2012, the "100L OK nozzle" was introduced. ■ Approximately one year later, clam catch increased. ■ In August 2014, the "500L" was introduced by the Shinji Lake Fisheries Cooperative. *For more detailed information about this case, please refer to the related links.

[Example] Use of fine bubbles in clam farming
Used a total of 6 "100L/min OK nozzles"! It became so clean that there is no need for cleaning.
Here is an example of using fine bubbles in clam farming. Immediately after generating fine bubbles, dirt surfaced to the extent that workers were reluctant to continue. One unit was used in this tank, and now the waste that had accumulated at the bottom has disappeared, making it clean enough that there is no need for cleaning. Additionally, a new tank compatible with fine bubble usage has been created. The ammonia concentration has drastically decreased. Furthermore, there have been reports that scallops and top shells suffer damage and die. Microbubbles may be clogging their respiratory systems. 【Sea Water Analysis Results for Clam Farming Tank *Evaluation: 1 is no problem, 5 is problematic】 <Water Quality Analysis Data: 15-ton Tank> ■Ammonia: 0.0mg/L - Evaluation 1 ■Nitrite: 0.0mg/L - Evaluation 1 ■Nitrate: 50mg/L - Evaluation 4 ■Phosphorus: 2.0mg/L - Evaluation 5 ■pH 7.5 *For more details on the case, please refer to the related links.

[Case Study] Floating Separation Experiment of Plastic Chips
In 10 minutes, nearly 100% of the cutting powder will rise! The specific gravity of plastic is greater than that of water and is negatively charged.
We would like to introduce a case study using the "7L/min OK nozzle" for the floating separation experiment of plastic shavings. 【Experimental Results】 ■ Nearly 100% of the shavings floated after 10 minutes ■ Almost 100% separation was achieved with fine bubbles It was also found that when the generation of fine bubbles was stopped, more than half sank ■ The items that sank were close to 1mm in size ■ The mechanism of floating is thought to be that positively charged particles gather around the negatively charged fine bubbles, and negatively charged shavings gather around them, resulting in flotation. *For more details on the case study, please refer to the related links.

[Case Study] Use of Nanobubbles in Irrigation Cultivation of Mini Tomatoes
Mini tomatoes thrive with nanobubbles! Depending on the variety, there are cases where the harvest increased by 5% to 35%.
Here is a case study from Kumamoto Prefecture using nanobubbles in the irrigation cultivation of mini tomatoes. In 2014, simply incorporating the "200L/min OK nozzle" into the existing pipeline resulted in an increase in harvest of 5% to 35%, depending on the variety. In 2015, by adding 10% oxygen and using the OK nozzle with pig manure, organic fertilizer was produced, leading to a 46% increase in harvest. 【Case Summary】 <2014> ■ Just incorporating the 200L/min OK nozzle into the existing pipeline ■ Harvest increase of 5% to 35% depending on the variety ■ Use of well water ■ Irrigation volume approximately 150% ■ Liquid fertilizer without solidification ■ Increased fertilizer amount ■ Irrigation tubes are cleaned *For detailed information about the case, please refer to the related links.

[Example] Custom nozzle with a small flow rate of 500 mL/min
Manufactured a 500mL/min nozzle! Adjusted to increase vacuum level, resulting in an increase in bubble generation.
We would like to introduce a case study using the '500mL/min small custom nozzle' from OK Engineering Co., Ltd. In July 2011, at a water pressure of 0.15MPa, the discharge rate was 410mL/min, and the vacuum level was approximately -0.03MPa under normal settings. A 500mL/min nozzle was manufactured, and adjustments were made to increase the vacuum level at the nozzle agitation section to -0.09MPa when the water pressure was 0.25MPa, resulting in a slight increase in bubble generation. Currently, we are ensuring that the vacuum level of the nozzle exceeds -0.05MPa at a water pressure of 0.15MPa. [Case Summary] <July 2011> ■ A 500mL/min nozzle was manufactured. ■ Since the generation amount is low, it is necessary to increase the vacuum level if required. ■ Adjusted to increase the vacuum level to -0.09MPa at a water pressure of 0.25MPa. ■ There was a slight increase in bubble generation. *For more detailed information about the case, please refer to the related links.
