Soil Purification Project
We propose an optimal purification method at low cost for soil purification and environmental conservation.
【Primary Methods of Soil Purification】
①Sand Purification System(SandPureSystem)
“On-site wet soil washing classification apparatus”

The “Sand Purification System” we successfully developed for assuming an important role in the circulating social creation is a compact and transportable unit-type wet soil washing classification apparatus.
Any contaminant is securely peeled off from the sediment by the strong cavitation generated through high-pressure jet stream, thus realizing high-level washing.

②In-situ purification method(On-site chemical treatmentIn-situ chemical treatment

A method to remove (detoxify) substances such as VOCs (volatile organic compounds) that can be decomposed on site.
Compared to excavation and removal, even when the concentration is low, the disassembly process can be cheaper.

Insolubilization method

A method that uses an insolubilizing agent to dissolve the toxic substances and meet the elution standard value.
Joined Sealing Soil Association, which uses natural materials for insolubilization.
* The revised Soil Contamination Countermeasures Law proposes inexpensive insolubilization as the following measures.
This is a measure for changing land over 900 m2 in abolished or operating factories.
As a measure that has an effect equivalent to or better than the indicated measure, high-concentration contamination is reduced to the target elution amount.

Excavation removal
A method of excavating and transporting all soil containing toxic substances and treating them properly at a processing plant.
This methool is used most often.

Energy-Saving Project
E mizu Shower
“Water spray system for outdoor units of air conditioner, chiller and refrigerator”
This system is intended to automatically spray water, from which the scale component has been removed through the reverse osmosis deionizer (water purifying apparatus) , so as to improve the efficiency of the outdoor-unit heat exchanger.
It produces a significant effect for power saving and Co2 reduction, thus contributing to the prevention of global warming.
