デュエルビッツブックメーカーurifying Soil and Groundwater

Adsorbs and degradation pollutants, rendering them harmless

デュエルビッツブックメーカー is for remediating land and underground water. By using the chemical reaction that occurs on the surface of steel powder, it adsorbs variety of heavy metals and decomposes organic chlorine compounds (VOC).
It is used for variety of purposes in civil engineering sectors such as remediating land during urban development, treating contaminated soil during tunneling, and suppressing underground water contamination.

Features

Eco-Friendly material process
By turning naturally occurring iron into powder and using it as a purification material, it returns to the soil after demonstrating its purification capabilities.
Large amounts can be supplied at stable quality
Stable quality is achieved, leveraging the expertise accumulated over many years.
Ease of use enabling simple handling
After a reaction has occurred, it can be separated from the soil through magnetic separation or other means, allowing for use at a wide variety of purification or construction sites.

Purification Principle

For Heavy metal adsorption

For VOC degradation

Performance

Heavy Metal Adsorption

Kobe デュエルビッツブックメーカーerforms adsorption performance tests using the following methods for five types of heavy metals, arsenic, lead, hexavalent chromium, cadmium, and selenium.
Even in a solution of heavy metals with concentrations exceeding standard environmental values, it has been shown that ECOMEL exhibits excellent heavy metal adsorption performance.

53NJ

Test method

Solution concentration: 1、10、100 mg/L
Substances: Arsenic, lead, hexavalent chromium, cadmium, selenium

Equilibrium adsorption amount of various heavy metals at environmental standard levels

Substances	Environmental standards (mg/L)	Equilibrium adsorption amount (mg/g)
Arsenic	0.01	0.1
lead	0.01	1.0
hexavalent chromium	0.05	0.6
cadmium	0.003	0.7
selenium	0.01	0.1

* White areas are below the lower limit of quantification. For hexavalent chromium, total chromium is analyzed.

VOC Degradation

ECOMEL is added to multiple types of organic chlorine compound solutions and shaken. The change in chlorine compound concentration over time is then measured to test the degradation performance.
The tests show that ECOMEL is able to quickly dechlorinate many organic chlorine compounds.

* Data using materials equivalent to 54NJ and 58NJ

Applicable Methods

ECOMEL can be applied to multiple methods.
Below, the most typical applied methods are shown for the heavy metal adsorption and VOC degradation, respectively.
