Do you have problems with treating soil or water contaminated with heavy metals and harmful substances?
During civil engineering work, you may encounter soil and water with excessive amounts of heavy metals and other contaminants.
It cannot be reused as landfill or disposed of with any process, therefore it must be transported to treatment facilities where the harmful substances are removed. This causes various issues including higher costs, longer project timeline and increased workload.
Metal Grid A:
a single substance to solve multiple problems
- Treatment of various heavy metals with one single substance reduces cost.
- Customizable form, composition and concentration for increased work efficiency.
- Possibility of reusing the contaminated soil and water, which decreases processing costs and workload.
Benefits of Metal Grid A
1.Treatment of selenium, fluorine, boron, and chromium VI, which has been difficult, is now possible with a single substance
Equilibrium adsorption test
(amount of substances absorbed, when it is equivalent to the soil leaching standards during the equilibrium absorption test)
| Absorbents | Arsenic V | Selenium IV | Selnium VI | Lead | Cadmium | Chromium VI | Fluorine | Boron |
|---|---|---|---|---|---|---|---|---|
| Our conventional absorbent | 1.5mg/g | 1.2mg/g | 0.5mg/g | 2.0mg/g | 1.4mg/g | - | - | - |
| Metal Grid A | 10.0mg/g | 4.5mg/g | 4.5mg/g | 4.0mg/g | 1.5mg/g | 6.5mg/g | 3.5mg/g | 1.5mg/g |
Absorption of arsenic, selenium, lead, cadmium, chromium, fluorine and boron
2.Customizable form, composition, concentration and more
As it is possible to adjust the form, composition and concentration for each usage, it not only exhibits excellent adsorption capabilities but is also easy to handle, reducing workload. It can be used over a wide pH range of 4 to 12 and is less affected by rainfall, making it effective in various sites where soil and water purification is needed.
- For contaminated soil remediation
- Method: adsorption layer method, dosage 30 kg/m³ or more
- For contaminated water remediation
- Method: purification plant, dosage 0.2 kg/m³ or more
- For groundwater remediation
- Method: Permeable Reactive Barrier (PRB), dosage 50 kg/m³ or more.
- For contaminated water remediation
- Method: purification plant, dosage 0.2 kg/m³ or more.
- For groundwater remediation
- Method: Permeable Reactive Barrier (PRB), dosage 50 kg/m³ or more.
- For contaminated water remediation
- Method: purification plant, dosage 0.2 kg/m³ or more.
3.Significant cost and labor reduction
The Metal Grid A is available at a reasonable price, as the main ingredients are silica, aluminum oxide, magnesium and other materials. In addition, since it can be filtered without electricity, operation costs are reduced.
Furthermore, since the soil and water containing harmful substances that exceeds standards can be recycled after purification, the total cost is more greatly reduced when compared to the disposal process.
