Achieving Water Circulation for Better Use of Urban Potential

Once upon a time, the city of Edo, old capital of Japan boasted the world’s
largest population of two million people. It was a model “Eco City”
harnessing trailblazing recycle system with carp swimming in waterways,
people enjoying thoroughly-installed waterworks, human waste completely
recycled. This way of making a city represented Japanese spirit just as ouraction to nature in country village forest, “Satoyama.”
We will continue handing down to our children such DNA of the Japanesemind by blooming it with modern technology. As the western-styleurbanization progresses in our land, water circulation has been worsening
ever more. In the midst of those circumstances, we have set our corporate
mission as restoring water circulation as close to that of nature as possible.
Toshikogyo Co., Ltd. are committed to be involved in the whole process ofurban water circulation from supply to drainage and help people to enjoy
better, comfortable and ecological life in our own way.

Greetings
We at Toshikogyo Co., Ltd. strive to achieve prosperity and progress of our three parties; ourvalued customers, society and environment at large and ourselves, through pursuing our businessof water environmental engineering.
How should we live our lives?” This question leads directly to the question of “What should a
corporate mission be? “ Toshikogyo Co., Ltd. has constantly been engaged in water environment
in cities since its founding in Meiji 42nd or 1908. Ever since several years before the millennium,
we have cast a question to ourselves: What should a company like ours inheriting our own roots
take on to exist in these times and in the future? After many rounds of soul searching and thoughtprocess , we have come to a conclusion and here is our corporate mission. That is “Restoring
Water Environment.”
We have come to believe that it is nothing but the pursuit of three goods of customers, society atlarge, and ourselves that needs to be done as our business evolution of our new era.
It goes without saying that among all values, the starting point of standard is “life at present.” At
Toshikogyo, we want to conduct our business to be good to “life at present.”
You may have heard the story of one drip of humming bird in the wildfire. We want to know ourplace and do our very best to fulfill such place. We will endeavor to be better today thanyesterday, and better tomorrow than today, proceeding to self-actualization through our dailyjob. Furthermore we do hope that this is going to be a booster for the self-evolution of all thepeople related to our enterprise.
Our corporate vision, “Co-existence, Co-Prosperity, plus Co-Evolution” is a crystal of our beliefs
stated herein. We keep this backbone deep in our heart in the execution of daily jobs.

Ultimate Water Reforming Technology
born out of the Nature of Japan
Water reforming device, THE BIOWATER was developed recreating nature of Japan rich in water resources. Water from therain soaking through the earth touches mineral crystal. Purified water gets back to the surface of the earth. This whole process
is now recreated by a fantastic device. This device contains a special ceramic fan made of heated artificial mineral crystals. We
use no filter. We add nothing to water. Nor we deduct nothing from water. We are simply recreating nature’ s wisdom. Oncetap water passes this device, water’ s character is modified to become natural water like “Iwashimizu” or “fresh and clear water
trickling out of rocks.” Installation is a very simple procedure – just to set it directly to your water supply pipe. Water pressure
propels the ceramic fans inside the device, requiring no electricity, saving the maintenance costs. The nature’ s mechanism ofJapan has blessed us with an ultimate water reforming technology, something we can pride ourselves on to our next generation.

THE BIOWATER enhances the Power of Water.
◎ Life Activating PowerCut flower lives longer. Animals and plants grow faster.
[Please refer to the left photograph.]◎ Antifungal Power

Effective microorganisms or favorable bacteria are activated to contain thegrowth of common bacteria, coliform, O157 or Legionella bacteria.

◎ Antioxidant PowerPower is enhanced to remove active oxygen which causes aging and disease.

◎ Cleansing Power

Cleansing power is strengthened from micro dust in manufacturing
precision parts to washing clothes at home.

◎ Environment Cleanup PowerEven waste water contains good amount of gases, activating aerobic bacteria
leading to the reduction of sludge and other pollutants. This lessens
environmental burden.

◎ Water Reform Keeping Power

Effect of water reforming is maintained for a long period. Laboratory test
demonstrated an effective period of over 10 months. In the field test, it was
confirmed to be effective after 5 years of use.
[Please refer to the right photograph.]

Cut flower is robust again.

Reforming power is maintained for 5 years.

We put a bouquet of dracaena in BW
reformed water, then roots started to
grow from the cut stem in 2 months.
After a year, the stem grew thick. After ayear and a half, roots grew to the size
nearly three times as large as the stem as
the photo shows.

(Water was filled in 2007, photo was taken in 2012.)

Elan Vital -Portable Water Reforming
System- changes tap water this much!
Elan Vital is a portable water
reforming device. By simply
putting it in a bottle, tap watertransforms itself into tender“Iwashimizu”
rock-produced clear water.
Chlorine in tap water remains effective for a long time while its odor
or bitterness is gone. Antibacterial and antioxidant effects are enhanced
to make water good, safe and healthy. Reforming sustainable period
is prolonged and long-term preservation of water is now possible.
Time required to reform is one hour per one liter as a rule of thumb,but the longer the time is the milder the water becomes. It works on well
water or other natural water as well as tap water.

Tap Water Test Piece Concavity and Convexity (BW unprocessed)[Proof 6] Rust and Decay Prevention of Water Supply Pipes■ JR Takasaki Station
Please find the three line graphs from our field test data from ourfunded research with Japan Railway (JR) Takasaki Station. We
compared the roughness of the bare metal after scraping the corroded
portions from the test piece. Test piece in which BW unprocessedwater flowed had severe roughness while the test piece in which BW
processed water flowed had smooth surface. In the comparison of
corrosion mass per area of the test pieces, BW processed water showed
less than half the amount of that of BW unprocessed well water and lessthan one third of that of BW unprocessed tap water. This confirms the
corrosion control effect of THE BIOWATER.

Oxide Layer Method

Ordinary “Red Rust Measures” treats the water supply pipe in some way or another. On the other
hand, our “Oxide Layer Method” using THE BIOWATER is a method to stop the red rust formation
on water supply pipes by reforming the flowing water itself. “Reformed Water” promotes the peelingof existing red rust and improves the pipe clogging. At the same time, it forms black rust and avoid thedeterioration of pipes. As a pretreatment, you may want to cleanse the pipe beforehand with hydrogen
peroxide solution or pressurized air to further increase the effectiveness of the method. “Oxide Layer
Method” enhances the grade of water itself on top of preventing water supply pipe from degrading.
Furthermore, our method brings about such benefit as bacteria prevention, enhanced cleansing power
and a host of additional effects on top of anticorrosion.

Mechanism of Oxide Layer Method
Inside the water reformed by THE BOWATER, a special mechanism works where the process ofoxidation takes place slowly as the chart demonstrates.

Stabilization andProtection of
Oxide Layer

No iron corrodes in water. The issue here is what kind of rust is formed. Rapid oxidation produces redrust. Slow oxidation produces black rust. Black rust prevents red rust from forming. “Fight rust withrust!” is the main concept behind such products as “weather proof steel” or “COR-TEN Steel.” Our“Oxide Layer Method” is a technology applying the same concept to water supply pipes. Once blackrust which is magnetite or ferrous-ferric oxide is produced, it forms a layer coating the inner surface ofthe pipe, halting the degradation of the pipework. Furthermore, there exists a special type of
microorganism called “Iron Bacterium” , which is deeply involved in the formation of rust. What isgreat is that water reformed by THE BIOWATER restrain the generation of iron bacteria as well. As
the chart shows, once we reform the water by THE BIOWATER, the physical feature of the water ischanged in a way to start the process of “red rust peeling and removal while forming black rust” ,protecting the pipework.

In general, well water with high degree of hardness is believed to be effective against corrosion.
One can confirm the difference of a significant degree not caused by the hardness of water but
by the existence of BW processing.

surface of the test piece. On the other hand, in the case of BW
mixed water, the degree of roughness is small. One can see aslow progress of corrosion on the entire test surface.

Case 3□ Kotesashi Heights Condominium Tower J in Tokorozawa City, Saitama PrefectureThis building was completed in February, 1985. In 2004, nearly 20 years after completion, they
researched various engineering methods to prevent degradation of water-supply pipes. After one-year of
field test, they installed THE BIOWATER on August 30, 2005. The type of water-supply pipe isinternally-coated lining steel pipe or VLGP pipe. This type of pipe has vinyl protection inside but thepipe end exposes bare metal, allowing the progress of red rust. Furthermore, pipe end allows the waterto get through, inviting corrosion of the iron which leads to leakage.

What happened to those two kinds of rust 5 years from installation is shown below.
①Rust at the Joint
Bare metal exposed section developed white calcium under which
solid black rust was formed. It should be noted that not only
black rust but also calcium layer is formed on top. You may recall
calcium corrosion control method. By installing THE
BIOWATER, one can expect the corrosion control effect by blackrust and calcium at the same time.

Calcium Layer and Black Rust at the Joint
Furthermore, after removing calcium layer theblack rust underneath is formed as if it wereartificially welded to surround the bare metal
portion.

②Rust spread between Vinyl Coated Layer and Bare Metal
Water penetrating to the gap between
vinyl coated layer and bare metal caused
degradation of the pipe. We came acrosscases like this occasionally and in all suchcircumstances they turned to be blackrust, putting a halt to the degradation asshown in these photos.

Big difference existed between
BW reformed water and BW
unprocessed water in the rustformation and corrosion level.
Reformed water had smoothand even rust overall, while therust of unprocessed water isuneven.
After removing the superficial
rust, We observed a big
contrast between them.

Rust of THE BIOWATER
reformed water had a thin layerof rust on the bare metal. Metal
layer remains to be smooth.
On the other hand, rust of
unprocessedwater had gouged surface wheret h e s u p e r fi c i a l r u s t w a s
removed. Bare metal was
corroded. In time, hollows areinevitable.

This test piece is actually used for water-supply
pipe as carbon steel tube. In the case of BW
reformed wwater, easy-to-peel thinmembrane-type rust was merely formed. In
one- year inspection, no sign of pitting
corrosion was seen. Meanwhile, for unprocessedwater rough rust like hump was formed. This
rust is hard and not easy to peel. Inner side of
the pipe saw progress of obstruction due to thistype of rust layer.

Above result confirmed the effectiveness of THE BIOWATER in preventing water-supply pipe in thatthe form and quality of rust developed differs completely whether we use THE BIOWATER or not.

Tulip Bulb for Hydroponic Culture
Disposal Loss Rate of 13% Up to Now
13% was broken down to 1 to 2% at purchase, 3% from fungi
during preservation, 3% from sprouting or rooting defects,
and 3% from budding.

THE BIOWATER

So they reformed the water for thishydroponic culture using THE BIOWATER.

All the bulbs spouted, which had never
happened before.

They grew steadily and they achieved
nearly 100% yield.

Furthermore, fungi attached to the bulb
disappeared entirely! [The object looking

Countermeasure against Scale

Mechanism of Scale Peel-off and Prevention by THE BIOWATER
Scale is a phenomenon resulting from deposition of calcium carbonate (CaCO3) or of silicon dioxide (SiO2)
on the inner surface of the pipework or of the water supply equipment. Mechanism of scale peel-off or
its prevention from attachment using water reformed by THE BIOWATER is as follows.

On Calcium Carbonate [CaCO3]
In case of Unprocessed Water
In most cases, cold or hot water is pressurized by pump and then sent tokitchen facilities. Because of this high pressure, a large quantity of gas is
dissolved in the water. Open the valve, and the pressure is reduced to anormal level, you will see the dissolved gas evaporating, creating a lot of
air bubbles.

In case of THE BIOWATER Reformed Water
On the other hand, in the case of cold or hot water reformed by THE
BIOWATER, the dissolved gas is not vaporized. Instead, the gas is either
incorporated in the sequence of water molecules ( clathrate hydrate) orpreserved in stable condition among the similarly sized particles of watermolecules. This is clear in that the normal “alkali shift” seen in ordinarywater is restricted in the case of THE BIOWATER reformed water asshown in the right-hand chart.

CaHCO3 (Water Soluble)

In the reformed water where carbon dioxide is dissolved in a large quantity even after opening the valve, alkali shift which is
caused by the vaporization of CO2 and generation of OH-. On the other hand, bicarbonate ion [HCO3- ] in the water
starts chemical reaction with calcium carbonate [CaCO3] to generate calcium bicarbonate [CaHCO3.] This calcium
bicarbonate is water soluble and starts to erode and melt the calcium carbonate which is attached firmly to the pipe as scale.
This results in the phenomenon where the scale peel-off in the normal water pressure takes place. (See above chart.)

In the reformed water, scale is formed as a deposit ofcalcite crystal (granular crystal.) calcite crystal is hard to
be attached as scale and even if it is attached, it is easy to
be wiped off. On the other hand, in the unreformed
water, aragonite crystal (needle-like crystal) is
deposited. It has a property to stick firmly as scale.

Case of Unreformed Water
Silica forms gelled coating by laterally connecting hands. This gelled coating accumulates one after
another to form a solid scale, which continues to build up inside the pipework.
In case of THE BIOWATER Reformed Water
In the BW reformed water, a phenomenon that water molecules surround silica or SiO2. This hampers
silica from connecting hands laterally, hindering the formation of gelled coating, preventing solid deposited layer of scale.

Water Inspection Institution: Bousei Co., Ltd. (Shinagawa Ward, Tokyo) took water on October 17,
inspecting the specimen on October 22, 2002.
Test Method:
We installed THE BIOWATER.and two sheets of Punchbox (PB hereafter)
to one of the two cooling towers of identical conditions.
We analyzed for each tower the following two respects①scale attachment situation ②salt chamber of cooling agent.
Test Results:
Cooling Tower 1 (with no BW processing)Cooling Tower 2 (with BW & Punchbox Immersion)

Large amount of scale is attached.

Scale is peeled off.

① Scale Attachment Condition
As seen from the photograph, scale is naturally peeling off from the filler of the cooling
tower with BW and Punchbox. As long as this continues to be used in this way,detachment of the existing scale proceeds with no new ones created and attached.

② Water Quality Test of Cooling Agent
Total iron value reduced to a large
degree from 0.85ppm to 0.11ppm.
This is because the occurrence of redrust was restrained.
Hardness rose dramatically from 136.5ppm
to 273.0ppm. This is because the detachment of scale initiated the melting of
calcium carbonate.
This test proved that THE BIOWATER has a superb effects of anticorrosion and scale detachment.

100% Yield for Heat Roll was constantly achieved!
Heat roll is considered the heart of office machines like copiers. This is because heat rollneeds to be perfectly circle so that the printed surface will not have thick and thin ink
spots. For this to be ascertained, all the heat rolls are checked before completion anddelivery. At times, hand polishing is done. Yield of this product has been increasing 1%
per year but it stopped at 95%. So they started to reform the water and the yield of 100%
was constantly achieved.

Longer Life for Ion Exchange Resin:

Case 1□ Japan Victor Corporation
Life of ion exchange resin is longer by approximately 40%.
Overview: This test was conducted at Kurihama Research Center of Japan Victor Corporation.
We installed THE BIOWATER to the immediate front of Ion Exchange
Resin and measured the difference in longevity against the one without BW.
The following is the summary of the test report sent from Japan Victor Corporation.
[Wordings are as reported in the original document.]
Purpose:To confirm how much longer the useful life of the ion exchange resin will getwhen it is equipped with THE BIOWATER 1-2-3.

Test Conditions: ①Ion Exchange Resin: C-40S, containing 40 liter of resin volume, made by Nippon Rensui Co.
②Water Activator: THE BIOWATER 1-2-3, ceramic water activator, made by Toshi Kogyo Co., Ltd.
③Measuring Instrument: KD-32 made by Kurita Water Industries Ltd.
④Test Period: April 4, 1996 through June 22, 1996
Results:

Useful life with water activator was 62 days, 17 days longer than the 45 days
with no water activator. [See the chart below.]

When we installed THE BIOWATER,
life extension effect to the ion exchange
resin was a longer life of 38%.

ーResin with Water Activator…Resin without Water Activator[Note 1] Normally, useful life of ion exchange resin is tested by molybdic acid methodmeasuring silica volume in the water in circulation. The volume of silica is
judged by the strength of fluorescent color which is caused by the reaction ofmolybdic acid and silica. In this test, the total volume of silica remained
unchanged before and after flowing throughTHE BIOWATER. However,nearly 20 % of silica did not react to molybdic acid. This is because 20% of
silica was clathrated or hydrated and did not bind with molybdic acid. It isbecause the creation of silica coating which reduces the life of ion exchange
resin was restrained due to the reformed water. Control of scale creation
resulted in longer life for the ion exchange resin.
[Note 2] Clathrate formation means “locking up in a cage.” Water molecule groupforms polyhedral grid structure and lock up other molecules. Locked up
molecules are kept from chemical reaction of displacement or chemical
combination. This is also called “hydration.”

Test Period:

April 15 through September 30, 2010

Test Method:

We used BW device to reform the tap water to be used forprocessing liquid of 40 liters. We provided additional supply of
BW reformed water when the processing liquid was not full.
We compared the useful life of ion exchange resin when
we used BW reformed water with the case when we did not.

Results①Before using BW reformed water, the usefullife of ion exchange resin was 1400 hours, while
after using BW reformed water, it became 2924
hours, approximately doubling the ion exchange
capability.
②Movement of Movable wire guide becames t a b i l i z e d , c o m p l e t e l y e l i m i n a ti ng t h ephenomenon of malfunctioning. This resulted
in the major reduction in down time of themachine during unattended operations.

Results are shown in conversion to enzyme volume called SOD [super oxide
dismutase]. It means that the higher the indicator is, the more super oxide is erased ormore superior anti oxidative power it has. As the table above indicates, tap water erased
40 units while BW reformed water erased 86 units. Test result shows that BW
reformed water has 2.15 times the super oxide erasing activity of tap water.

Enhanced Anti Oxidative Power:

Case 2□ Measurement by Kanagawa Dental College
Case of Sister Product, Elan Vital Six times more antioxidant!

Superoxide Erasing Activity[measured by electron spin resonance method]
Reformed water has approximately
six times superoxide erasing activity.
Superoxide is deemed to cause
disease and aging.
