Greetings
Taking advantage of my 40 years of experience in designing exclusive machine tools, I have developed the loop flow OK Nozzle. There are nearly 100 types of loop flow OK Nozzles designed and manufactured so far. In particular, the field of application of fine bubbles is so wide that we are currently focusing on manufacturing “special order OK nozzles” to support each purposes.
We believe that generating and using fine bubbles will lead to the restoration and protection of the natural environment, and if we do this consciously, we will be able to protect the environment more efficiently. I feel that the time will come when it will be used in many homes, in many rivers, in the sea, on the coast, in sewage treatment plants, for factory waste liquid treatment and so forth. In the fields of agriculture and aquaculture, the power of fine bubble bioactivation has made it possible to increase food production at low cost. In the same cultivation house for irrigation of cherry tomatoes, the harvest has increased by 46%, and in flounder farming, the weight has increased by 20%. We hope that this business will be an opportunity to create new industries. Also, I will greatly be happy to work with you for that purpose.

Having been researching fine bubbles since 2000 and in September 2006, a loop flow fine bubble generating nozzle was developed. The idea of nozzle mechanism flashed though my mind in July 2006, watching the stealth bubbles during a water-bloom surfacing experiment in a rice field.
