In the treatment of contaminated soil in industrial legacy sites, mines, and other areas, pollutants such as heavy metals and organic substances are firmly attached to soil particles. Traditional remediation methods either struggle to completely remove these pollutants, or they require long treatment cycles and high costs. Desen Environmental’s Ex-Situ Soil Washing Remediation Equipment, with its core logic of targeted removal and efficient treatment, has become a key tool to solve such problems.  

The core advantage of this equipment lies in "precision washing":  

It adopts a multi-stage washing process. First, special chemicals are fully mixed with the contaminated soil. Utilizing the targeted adsorption property of the chemicals, pollutants are stripped from the soil particles. Then, combined with a multi-stage separation system, the pollutant-containing washing solution is accurately separated from the clean soil. After dehydration and passing compliance testing, the clean soil can be directly backfilled. The pollutant-containing washing solution is then sent to a subsequent treatment system for recycling or discharge up to standard, avoiding secondary pollution.  

At the same time, the equipment continues Desen Environmental’s design concept of "modularization + intelligence":  

- The modular structure can be flexibly combined according to the scale of the contaminated site, eliminating the need for large-scale infrastructure construction.  

- The intelligent control system can real-time monitor key parameters such as washing concentration and soil moisture content, and automatically adjust process parameters. This not only ensures stable remediation effects but also reduces manual intervention.  

In a heavy metal-contaminated site treatment project, this equipment could process 80 cubic meters of contaminated soil per day, with a pollutant removal rate of over 90%, and the overall remediation cost was 15% lower than that of traditional processes.  

From remediation efficiency to environmental protection standards, Desen Environmental’s Ex-Situ Soil Washing Remediation Equipment not only solves the pain points of difficult-to-clean and slow-treatment of contaminated soil but also realizes a closed loop of treatment, reuse, and emission reduction. Its application provides a reliable solution for the rapid remediation of moderately and heavily contaminated soil and also presses the "accelerator button" for soil ecological restoration.
