• Parts and Materials

The "Iron Powder Cartridge Method" is a technique suitable for VOC pollution control without drainage and additives. By installing the iron powder cartridge in a well and operating it, VOCs are decomposed by the action of the purifying iron powder, effectively addressing high concentrations of contamination. Additionally, there are no additives introduced into the groundwater, and ground subsidence does not occur. 【Features】 ■ Install and operate the iron powder cartridge in the well ■ Decompose VOCs using the purifying iron powder, effective for high concentrations of contamination ■ Gradually purify the surrounding area by circulating groundwater underground ■ Deploy multiple cartridges according to the spread of contamination ■ VOCs are decomposed underground with no impact on the surface *For more details, please refer to the PDF materials or feel free to contact us.

• Special Construction Method

We would like to introduce our heavy metal adsorbing iron powder 'MSI-X'. The dissolution of Fe lasts for a long time, providing high adsorption persistence. It is ferromagnetic and has a high specific gravity, making separation and recovery after adsorption easy. In previous soil washing methods, there were costs associated with the disposal of the fine particles generated in a certain amount, but since the recovered iron powder can be reused repeatedly, cost reduction is possible. 【Features】 ■ The particle size is not too fine, and the high specific gravity makes it less likely to scatter (good workability). ■ The dissolution of Fe lasts for a long time, resulting in high adsorption persistence. ■ The pH is neutral, so there is no impact on the surrounding environment. ■ It is ferromagnetic and has a high specific gravity, making separation and recovery after adsorption easy. ■ The specific surface area is large, improving reactivity and adsorption performance. ■ It has been treated with a catalyst, resulting in high initial reactivity. *For more details, please refer to the PDF document or feel free to contact us.

The "Bioremediation Method" proposed by JFE Mineral allows for in-situ decomposition and on-site purification that is environmentally friendly and economically advantageous. It enables purification of groundwater contamination at a lower cost compared to other methods. The deeper the contamination, the greater the cost benefits. Additionally, the purification effect lasts for a long time, making it effective in preventing rebound. 【Features】 ■ Complete purification at low cost ■ Suitable for a wide range of soil types ■ Effective in preventing rebound *For more details, please refer to the PDF document or feel free to contact us.

The "VOC Bioremediation MED Method" decomposes contaminants through dechlorination using inexpensive and safe bio-nutrients. Nutrients for microorganisms are injected into the soil and groundwater to promote the dechlorination reaction of VOCs underground. This method is suitable for low-cost purification of deep soil and groundwater without the need for excavation or disposal of contaminated soil. 【Features】 ■ More affordable compared to conventional poly-lactic acid, high fatty acids, and amino acid-based nutrients ■ Safe as it is based on plant-derived materials, harmless to humans, animals, and plants ■ Contains organic acids and amino acids, covering essential nutrients for anaerobic microorganisms *For more details, please refer to the PDF materials or feel free to contact us.

"STA-M" is an insolubilization and solidification material primarily composed of magnesium oxide (MgO), which is produced by firing magnesite (magnesium carbonate), a natural material, at approximately 800°C. By adding inorganic materials to the main component MgO, it is possible to insolubilize all regulated heavy metals. The material is in the form of a white powder with a particle size of less than 1mm, and it exhibits insolubilization and solidification effects through the reaction between MgO and the added inorganic elements. 【Features】 ■ The pH after treatment is below 10.5 as it does not contain calcium-based materials. ■ It does not cause high alkalinity issues. ■ It has a large specific surface area, making it highly reactive with soil particles and heavy metal ions. ■ Compared to cement-based solidification materials, it has a lower pH and a reduced risk of re-dissolution of heavy metals. ■ The insolubilization effect is sustained over a long period. *For more details, please refer to the PDF document or feel free to contact us.

In conventional methods, a large amount of water is sent into the ground, causing the surface to become muddy; however, in this method, the amount of water used is small, resulting in less impact on the ground. Additionally, there were disadvantages such as the need for large plants and the issue of generating a significant amount of sludge. This method resolves these problems by using foam instead of the water traditionally used. 【Features】 ■ It is a new in-situ decomposition method. It can purify VOC contamination in a relatively short period. ■ No sludge is generated, and it does not significantly impair soil bearing capacity. ■ The plant size is small, making it possible to work in narrow spaces. ■ It solves the issues of sludge and plants, achieving significant cost reductions. ■ It is an environmentally friendly method due to the low amount of water used. *For more details, please refer to the PDF materials or feel free to contact us.

The "MSI-N901T" is a high-performance iron powder specially processed to quickly decompose and neutralize volatile organic compounds (VOCs) contained in soil and groundwater. Thanks to the effect of a special catalyst, VOCs undergo dechlorination, resulting in a reaction where chlorine is replaced by hydrogen, thus neutralizing them. Furthermore, a potential difference occurs between the catalyst and metallic iron, leading to a "local battery reaction" that enhances the reaction speed and demonstrates powerful decomposition performance. 【Features】 ■ High decomposition performance ■ Excellent economic efficiency ■ Superior workability ■ Material that generates little dust ■ No leaching of heavy metals, etc., in soil and groundwater *For more details, please refer to the PDF materials or feel free to contact us.
