Environmental Products

MT-V3^TM - Iron oxide-based VOCs decomposer -

Strengths

1. Strength 1
   By-products of titanium dioxide (iron oxide) with high functionality added by our proprietary ultrafine particle technology
2. Strength 2
   pH neutrality and the ability to decompose VOCs safely and easily
3. Strength 3
   No generation of harmful by-products
4. Strength 4
   Simultaneous solidification and purification can be performed when combined with a neutral solidifier.

Typical Applications

• In-situ purification of VOC-contaminated soil
• Purification of VOC-contaminated groundwater with permeable purification walls

Chief components

• Iron oxide
• Iron powder

Intended use

• Decomposition of VOCs (Trichloroethylene etc.)
• POPs including dioxin and residual agricultural chemicals can also be decomposed.

Decomposition test of Trichloroethylene

The amount of chloride ions as decomposed material almost equals the theoretical amount, so no harmful by-products are generated through the decomposition process.

Free from rusty water
