Nano bubbles have a diameter of fewer 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.

Nano Bubble

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 a 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 begins to re-grow.

Nano Bubble Solutions

• Increased levels of Dissolved Oxygen (DO)
• Reduction in Biological Oxygen Demand and Chemical Oxygen Demand
• Eradication of fish kills that have historically occurred annually
• Eliminates Hydrogen sulfide thus preventing unpleasant odors
• Water clarity increases allowing sunlight to penetrate the water
• Aquatic life returns
• Pond and sea bottoms restored, sediment and sludge cleaned over time
  for healthier return of different aquaculture species
• In an application where sludge is present, volume of sludge is reduced

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 to 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. Read More >>

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
