Nano bubbles have a diameter of less than 50 microns and unique physical characteristics that differ from other types of bubbles. They are too small to rise up through liquid and get compressed by negative ions at the gas-liquid interface so they don’t combine to form larger bubbles. This means they remain in the liquid for a long time. They eventually shrink leaving their entire gas load in the liquid. Nano bubbles are generated using various methods. It is only Anzaikantetsu MCS Patented Carbon Ceramic Nano Bubbler technology that provides the most efficient process that generates the smallest nano bubble and at the largest concentration. With this method a vapor phase is formed via venting through nano-level ultrafine pores, and then a liquid flow over the ultrafine pores boundary that precisely ends the vapor phase. This then results in the generation of ultrafine bubbles. Any gas into any liquid.

There are many ways to inject air into the water volume such as a fountain or a mechanical aerator.  These technologies do add oxygen to the water but most of it will be lost to the atmosphere when it rises through the water column to the surface.  Nano Bubbles on the other hand Do Not rise; they actually stay suspended or even sink in the water column.

The nano bubble is unique in that it is not very buoyant. The bubble surface takes on a negative ion charge further raising the surface pressure at the liquid gas interface. This phenomenon causes the bubble to sink and will help transfer oxygen to depth as it slowly diffuses.

As the ultra-fine nano bubble sink as it continues to shrink in size. The added benefit of a nano bubble is the half life of about 15 days.  Towards the end of this cycle the bubble will implode onto itself releasing the Oxygen at depth where it is most needed. This activity will prevent the formation of odor producing bacteria and further algal growth. Turbidity of the water column will be reduced.

When the bubble implodes it will release OH- (Hydroxyl radical) which in turn offers remedial oxidation potential that cleans contamination while also releasing additional localized oxygen from the water molecules. It has also been observed, the nano bubble will penetrate silts, soils and sediments found on lake bottoms. Lake bottoms are slowly restored as dissolved oxygen levels rise, organic masses reduced and aquaculture begin to re-grow.

  • Agriculture
  • Tanker Truck Wash out Facility
  • Hydroponic
  • Fish Farming
  • Aquaculture
  • Pond restoration
  • Oil and Gas Frac Flowback
  • and more…

Nano Bubble provides increased DO for it is maintained throughout the water column. Even more important, the Nano Bubble will sink to where the molecular changes are initiated, furthest away from the atmosphere and sunlight and where settled solids collect on the bed of the formation. Overall the use of Nano Bubbles will provide better results in reducing algae growth by increasing the dissolved oxygen in the water column much better than traditional aeration techniques. It has been determined that the Nano Bubbler can inject 1,000,000,000 Nano Bubbles into a cubic centimeter. 1 milliliter of water fits into a cubic centimeter.

Nano Bubbler advanced aeration starts turning over the waterbody and increases the microbial breakdown of organic sediment in both the water and pond/seabed sediment. This process increases dissolved oxygen and reduces odor without the use of chemicals, naturally, reducing the need for harmful chemicals. The Nano Bubbler eliminates the need for any filtration, or use of harmful chemicals or even the potential need to treat with then remove chlorine prior placing water back in ponds.

Project to Eliminate Blue-Green Algae at the Outer Moat of the Imperial Palace Hibiya, Tokyo

The Algae problem of the Imperial Palace Moat, Tokyo, has been reported on many occasions in the Japanese media, especially the Hibiya Outer Moat, which is the main focus of this project. Located at the water gate output point, it has a problem not only with Algae layers, but also odour in the main entrance of the Royal Palace. The Japanese Government investigated many solutions, but finally decided that Anzai Kantetsu Co. Ltd., should be involved in this project, using its patented Nanobubble. Read More >>

Colon Bacillus Trials on Lake Biwa – Japan

Lake Biwa is the largest fresh water lake in Japan, located almost in the centre of country, it is 70 miles east of the ancient capital of Kyoto. The area is approx. 5.5 times that of the heavily polluted Lake Apopka in Florida. At a length of 40 miles, the lake is a popular recreation spot for swimmers, water skiers, campers and fishermen.

Reduction of Sludge – Lake Hyōko – Japan

Lake Hyōko (瓢湖) is a 281-hectare (690-acre) reservoir area in the city of Agano, Niigata, Japan. (Extracts taken from longer report). The reservoir was created in 1639 during the Edo period of Japanese history. It is noted for its abundant and diverse bird life, and is an important overwintering grounds for Whooper swans and Tundra swans. Read More >>

Remediation of Lake Suwa – Japan

Lake Suwa has a long history of being polluted, mainly because its water arrives from many different sources, from the highly populated and industrial local area. It has been the focus of water pollution/remediation analysis for over a hundred years, with much of the data remaining on public record. Read More >>

Red Tide – Seto Inland Sea – Japan

The Setouchi region is known for its moderate climate, with a stable year-round temperature and relatively low rainfall levels. The sea is also famous for its periodic red tides (赤潮 akashio) caused by dense groupings of certain phytoplankton that result in the death of large numbers of fish. Read More >>

Example of water quality improvement at Hakkeijima Island by introduction of micro nanobubble generator employing ultrafine pores

Although ultrafine bubbles have come to be used in various fields for some time now, there has not been enough discussion concerning enlarging the scale ultrafine bubble generating equipment and making it more energy efficient. This is particularly an important theme for purification of seas, lakes and rivers. The possibility of employing our unique technologies for enlarging scale of and making such equipment more energy efficient for improving marine environments is now being considered. Read More >>

Aichi Environmental Award 2019
Won by Nagasaka Eel Farm using Anzai Nanobubbles

Aichi is a Japanese prefecture in central Honshu Island and an area known as a top producer for farmed eel. Eel is a very popular food in Japan, with the high eating season in the summer months. In 2015, in order to increase productivity and reduce energy costs, Nagasaka Youman (Nagasaka Eel Farm) in Nishio City, engaged Anzai Kantetsu to install its patented Nanobubble technology.

Prawn Farming in Ariake Sea in Southern Japan

The Ariake sea is the biggest tide-land in Japan. It covers an area of 20,000 hectares. The prawn catch in this area has drastically reduced over recent years. The local governments, Fukuoka, Kumamoto, Saga, & Nagasaki, decided to jointly release a batch of farm raised prawns into the sea. From 2004, Arao Fishermen’s Cooperative Association (AFCA) was entrusted by Kumamoto prefecture, with intermediate breeding of prawns and to discharge the prawns into Arao area of the Ariake Sea.

What are Micronano Bubbles?

As is obvious from their name, “micronano bubbles” are extremely small gas bubbles. But their diameter has not yet commonly been defined even in the Japanese Society for Mutiphase Flow. From the physical point of view, however, it seems appropriate that gas bubbles whose diameter is less than 50 microns are referred to as the micronano bubbles. Read More >>
