The Desen soil washing system is designed to reduce pollution and promote the reuse of contaminated soil. By separating heavy metals, petroleum hydrocarbons, and other pollutants from soil particles, the system helps restore soil to a condition suitable for safe reuse or further treatment. The equipment does not rely on fixed facilities and is composed of standardized modular units that can be configured as integrated plants or vehicle-mounted systems according to project requirements. Once transported to the site, the system can be quickly installed and put into continuous operation within a short time.

All treatment processes take place within a closed operational system. Soil is fed into the processing line, where it is first loosened and classified by particle size. It then undergoes scrubbing and washing processes that detach contaminants from soil particles. The resulting washing wastewater enters the integrated water treatment unit, where it is purified and recycled back into the washing process, eliminating external discharge. After treatment, soils of different particle sizes are separated and collected. Reusable soil fractions can be returned directly to the site, while finer contaminated materials requiring further treatment are handled separately to ensure proper management.

During operation, the system is designed to minimize environmental impact. The enclosed structure prevents dust emissions, and treatment chemicals circulate within the system to reduce secondary environmental effects. The control interface is simple and user-friendly, allowing operators to adjust washing intensity and chemical dosage based on contamination levels and soil characteristics. This helps achieve effective remediation while minimizing water and chemical consumption.

The integrated configuration is well suited for long-term, centralized remediation projects, where processing capacity can be adjusted by adding or removing functional modules. The vehicle-mounted configuration, on the other hand, is ideal for distributed remediation tasks across multiple sites, offering fast relocation, a small footprint, and immediate operational readiness upon arrival.

With its continuous processing capability, mobility, and closed-loop resource utilization, the Desen soil washing system adapts to different contamination types and site conditions. It transforms complex soil remediation processes into more controllable and efficient operations, providing reliable equipment support for environmental restoration and enabling contaminated soil to move from “requiring treatment” to “being safely reused.”
