Dear Mr./Ms. Aeration staff
Nice to meet you, my name is Fujisato Tetsuhiko from Bubble Tank Co., Ltd.
We manufacture and sell parts used for water treatment in Japan.
We will introduce equipment that can dramatically increase the amount of dissolved oxygen simply by arranging equipment on the upper side of the air diffuser pipe that is already installed in the aeration treatment tank and catching the rising bubbles.
We hope that by establishing excellent water treatment technology, humankind can survive with less energy.
This is an image showing the behavior of treated water and gas by skeleton equipment.
This is a youtube video of the behavior of water and gas.

The fourth from the top of the Google English translation URL below is the aeration booster.

This is a YouTube video of supersaturated water.
Please click to see.

The purpose of this video is to point out that the "gas contact method," which is traditionally considered good, is not the best.
The two methods mentioned above, bubble aeration and microbubbles, are both not very efficient.
When bubbles are placed in a liquid, the gaseous component hardly dissolves.
The components of bubbles in water do not dissolve into water during ascent, but dissolve into the liquid film at the moment the bubbles are destroyed at the water surface.
The video in the URL below is the device with the highest dissolution rate.
When all the liquid ejected from the upper nozzle overflows from the container, it is discharged as a thin film.

As most of the wastewater discharged on a daily basis around the world is treated, conventional aeration treatment is considered to be acceptable.
However, this video shows that it is possible to increase the amount of dissolved oxygen in wastewater simply by collecting bubbles, without consuming any new additional energy.

Very little progress has been made in aeration equipment due to the common belief that dissolution rates increase when the contact area and contact time are large and long.
Much energy is thrown away wastefully at present.
Oversaturated water (Sewage treatment water is mainly supersaturated water with nitrogen gas.)
