Heavy metal contamination in soil is highly concealed and difficult to remediate. Ions such as lead (Pb), cadmium (Cd), chromium (Cr), and arsenic (As) can persist in soil layers for long periods. They may infiltrate groundwater through rainfall, inhibit vegetation growth, and pose serious risks to surrounding ecosystems and human health. Traditional ex-situ remediation requires large-scale excavation and transportation, leading to long construction periods, high costs, dust emissions, and secondary pollution risks.
To address these challenges, Desen Environmental has developed an in-situ heavy metal soil stabilization system designed for efficient, low-disturbance remediation. Without soil excavation or off-site transport, the equipment enables on-site long-term immobilization of heavy metals, effectively blocking contamination at its source.
Targeted in-situ stabilization technology
The system adopts a targeted in-situ stabilization process that integrates precise reagent dosing, deep mixing, and uniform solidification into one operation. It works directly on contaminated sites without the need for a fixed plant or large-scale earthworks.
Based on contamination depth, heavy metal type, and concentration, the system accurately adjusts stabilizing agent dosage. Through a deep mixing mechanism, the reagents are fully blended with contaminated soil, rapidly forming stable, insoluble compounds. This process effectively prevents metal ions from migrating or leaching, ensuring long-term contamination control.
Mobile integrated design for flexible deployment
The equipment features a mobile integrated structure, allowing fast deployment across different site conditions. It requires no construction of permanent facilities and causes minimal disturbance to existing soil layers and surface environments.
It can be rapidly deployed to industrial sites, brownfields, farmland, and scattered suburban plots. Whether dealing with single-metal contamination or complex multi-metal pollution, the system achieves stable immobilization performance, with leachate concentrations reduced well below environmental regulatory limits after treatment.
Clean, safe, and highly automated operation
The entire system operates in a fully enclosed, dust-controlled environment, with no wastewater or exhaust gas leakage. Low-noise operation ensures minimal disturbance to nearby communities and ecosystems.
High automation reduces labor requirements, while key components are built for durability and long-term continuous operation. Routine maintenance is simple and cost-effective, making it suitable for long-duration remediation projects.
Efficient solution for long-term soil protection
Desen Environmental’s in-situ heavy metal stabilization equipment delivers a low-disturbance, high-efficiency, and long-term contamination control solution. It eliminates the need for soil transport, reduces environmental risks, and significantly shortens remediation timelines.
By stabilizing contaminants directly at the source, the system helps contaminated sites achieve compliance faster while protecting soil health and surrounding ecosystems—providing a reliable solution for sustainable land restoration and environmental safety.
