River & Lake Water Puriﬁcation System

How do you dissolve oxygen in water ?
Isnʼt aeration in a “goldﬁsh tank”! the method that comes to mind?
Aeration is the method of passing air through water, which is a technology in wide
general use.
Today, much development of the technology is aimed at making the bubbles smaller.
However, surprisingly, the point is often missed that it is because the gas is notdissolved in water that bubbles are formed no matter how small the bubbles are
made to be. (Aeration is a technology that is safe to the eye.)“NEW TECHNOLOGY”

Our dissolution technology was inspired by “thinking in reverse”: to pass water
through gas, rather than gas through water. It utilizes the subtle diﬀerence between
atmospheric pressure and the pressure inside the apparatus.
Hardly any bubbles are generated because the gas is almost completely dissolved.
The eﬃciency of dissolution is nearly 100 percent with this technology.

There are gaps in water !
This property of water, of having gaps, is exploited to dissolve the gas.
In water, there is gas (air) that is originally dissolved in these gaps. This gas isreplaced by another gas with the purpose of dissolution. This replacement
dissolution technology has been made possible by the “high-concentration gas
dissolver” apparatus.

Remediation of foul odors
and reduction of sludge volume

Cleanup of Contaminated Soil

It is said that, when a cup is ﬁlled with water, the ﬁlling
fraction of the water molecules is about 40 percent!

And the gaps are

60 percent !

The high concentration O3 dissolution
deodorization, decolorization, and sterilizationThis technology will overturn conventional wisdom!
Various gases (single elements) are dissolved in water.
O2 (oxygen) O3 (ozone) N2 (nitrogen) H2 (hydrogen) CO2 (carbon dioxide) etc.!
For example, the air dissolved in water is replaced with pure oxygen or one of avariety of gases such as ozone, nitrogen, hydrogen and carbon dioxide.
The high-concentration gas dissolution technology is being utilized in various ﬁelds!

Drainage puriﬁcation, bad smell improvement

Examples of use“Wastewater Treatment”

Aquarium / Aquaculture

Dissolution of pure oxygen, not aeration with air! This alone makes the oxygen
concentration about 4.8 times higher. Compared to aeration with air, thediﬀerence in dissolution capability would be 50〜100 times under the same
conditions. This high dissolution capability has made it possible to meet therequirements of wastewater treatment. In addition, remediation of foul odors
and eﬀects of reduction of sludge volume have also been found in wastewater
treatment sites.

“Cleanup of Rivers and Lakes”, “Measure Against Algae Bloom“,“Measure Against Red Tide”, “Measure Against Blue Tide”

Puriﬁcation of lake

Since the cause is the shortage of oxygen at the bottom of the water, thetechnology to increase the concentration of dissolved oxygen at the bottom of
the water solves the problem.
In rivers and lakes with deposits of sludge, as well as in polluted seas, just by
making the bottom of the water an oxygen-rich environment, an array of aerobic
bacteria will promote the cleanup by decomposing the pollutants. Blooming ofalgae will be suppressed by eluting and decomposing nutrient salts.
This apparatus makes it possible to increase the concentration of dissolved
oxygen at the bottom of the water, which was a diﬃcult thing to do withconventional technology.

“Aquarium / Aquaculture”

Manufacture of functional water

Aerating bubbles get in the way of viewing by the visitors in an aquarium.
The use of this apparatus has made the technology friendly to both ﬁsh and visitor.
It is also popular in aquaculture farms, where many ﬁsh are raised, for its power insolving the problem of shortages of dissolved oxygen caused by dense farming
and by poor water quality.

Algal growth system display model“Hydroponic / Solution Culture”

Healthy crops are grown with high-concentration oxygenated water which
provides the necessary oxygen to the roots and activates bacterial action.
Growth is promoted as a result of the activation of photosynthesis by using
water with dissolved carbon dioxide.
The pH of the solution can be easily adjusted as well.

“Cleanup of Contaminated Soil”

Good results achieved by the cleaning eﬀects of the combined use ofhigh-concentration oxygenated water and soil bacteria as a measure to clean up
soil contaminated by oil leakage is gaining attention both inside and outside Japan.

“Deodorization / Bleaching / Sterilization”

Hydrogen sulﬁde removal

O3 (ozone) does the job. No scent of ozone is released in the surroundings
because it is almost completely dissolved in the water. It is possible to use ozone
gas, which is harmful in a sense, safely and with high eﬃciency.
Solutions of more than ORP800mv and at concentrations higher than 5PPM canbe obtained.
“CO2 is a Natural Resource”
CO2 is separated from such gases as chimney exhaust fumes or natural gas anddissolved in water. This helps the solution of such issues as the environmental
problem, the food problem and the energy problem by its enhancing eﬀects on
the growth of plants and in the aquaculture of algae.

Water quality improvement“Functional Water”

Replacement of oxygen in water with nitrogen …… prevents oxidation andputrefaction.
High-concentration hydrogenated water and oxygenated water are being used
for such purposes as drinking water.
The pH is adjusted by dissolving carbon dioxide.

“Remediation of Foul Odors”

Wastewater treatment

Organic matter in water is mineralized by the work of bacteria. An environment
with an insuﬃcient amount of dissolved oxygen becomes a domain in whichanaerobic bacteria thrive, in which the organic matter is converted to suchgases as ammonia, hydrogen sulﬁde and methyl mercaptan, generating foul odors.
No foul odor is generated in a domain in which aerobic bacteria thrive in anenvironment with a suﬃcient amount of dissolved oxygen.
