Harmful Pollutant Erasing
Soil Purifying Liquidマイスター株式会社

Characteristics of the purifying liquid

For a cleaner earth
Harmful pollutant erasing
soil cleaning liquid
Turns soil that has been polluted by heavy
metals and dioxins into a clean state in ashort period.
Without using heat, applying pressure nor
producing any carbon dioxid making it avery environmentally friendly purification
method.
Noneed of any expert knowledge/
expertise as it can be set up easily with
common construction machines at theplace of use.

Purification
aid liquidThis liquid can break down molecules to
2 nano-sizes. It is composed of chemical
enzyme generating liquid and refined water.
It breaks up the benzene ring to safely
do oxidative decomposition. ( oxidativedecomposition using liquids with nitric acidadded to it are known, but to clean the soil,
our recommended molecule break down liquid
is best.)Purification process

Purifying liquid
Uses water, enzymes, zeolite, carbon and other natural
materials as raw materials to be friendly to the environment.
Safe and reassuring for users and residents near.

Special carbon
and zeolite

Carbon is made from a special fineprocessing of plant based carbon.
30 angstrom sized pores form on thesurface of the carbon creating various
shapes of fullerene (soccer ball type,carbon nanotube type, buckyonion type,horn type) 10g of this special carbon
with a specific surface area of 1200 to2000 m2 /g could absorb gas the volumeof the Tokyo Dome.

Mixing the two together
increases the purifying effect.

Analysis and setting up

マイスター株式会社

Analysisof the soil

An analysis company will collectsome soil by boring before thepurification process begins. The
collected soil and ashes will beanalysed to determine the pollution
levels and the pollutants present
in the soil. This information will betaken into consideration for theprocess of application and type of
purification liquid that will be used.

Collecting the soil
Planting the rod

The usually recommended expertise/ expert knowledge is unnecessary. We use aenvironmentally friendly purificator that doesn’t use heat, apply pressure or produce any
CO2. Nor is any special brand is needed. It is a eco friendly process that only kneads andstirs the soil. The depth of the pollution erasing is up to 100m*.
* separate consultation is necessary for purification deeper than 30m

The boring machine can move making it
possible to purify up to a specific deepness
without the necessity of procedures such as
drilling to apply the purification process fastand repetitively to the planned area.

5Mechanism of the purification

マイスター株式会社

adsorps and decomposes the pollutants
in a short period of 1 to 2 months after
processing for a healthy soil.

Approximate time ofrest needed for the soil

due to the effects of the harmful pollutant
erasing soil purifying liquid, harmful pollutants
get adsorped immediately after applicationand start to decompose. Also, by letting thesoil set to cure, the effect increases, working
on almost all pollutants in the soil.
