DOWA Ecosystem Soil Purification Technology
DOWA Ecosystem's soil purification business conducts a comprehensive process from investigation to purification treatment and monitoring.
We assess all conditions comprehensively to select the optimal treatment methods such as soil washing, chemical/thermal decomposition, and biodegradation. We address a wide range of issues, including not only heavy metals but also VOCs (volatile organic compounds), oil contamination, buried waste, and complex pollution.
■ Soil and groundwater contamination investigation
- Abundant track record
- With over 20 years of experience and know-how, we conduct efficient, accurate, and detailed investigations and consulting.
- Since we can handle everything from investigation to purification consistently, we provide reliable and reassuring support.
■ Decomposition using iron powder for soil purification
- Iron powder for soil purification developed and improved uniquely by the DOWA Ecosystem Group.
- Efficient construction with DIM (Direct Iron Mixing), capable of construction up to 60m with a three-axis auger.
- Pre-treatment allows for the purification of "complex contamination with oil and VOCs."
■ Metal recycling from contaminated soil
- Recycling lead from soil containing lead bullets at shooting ranges.
- Diverse treatment technologies (pumping treatment, biodegradation, chemical oxidation decomposition).
