In soil remediation projects, challenges such as scattered contaminated sites, complex working conditions, tight deadlines, and the risk of secondary pollution have long impacted project efficiency and cost control. As the world’s first vehicle-mounted integrated soil washing system, the Desen Environmental Mobile Soil Washing Unit is designed around three key advantages: mobility, instant deployment, and intelligent operation. By eliminating the limitations of traditional fixed treatment facilities, it delivers a revolutionary solution for ex-situ soil remediation projects.

1. Vehicle-Mounted Integration for Rapid Deployment

The Desen Mobile Soil Washing Unit integrates the complete remediation workflow into a standardized mobile platform, including:

• Soil screening and pre-treatment

• Soil washing and contaminant removal

• Chemical dosing and mixing

• Wastewater recycling

• Solid-liquid separation

Designed to meet transportation requirements, the unit can be easily relocated by trailer, enabling flexible operation across multiple sites without geographical limitations.

Unlike conventional remediation systems that require extensive civil construction and lengthy installation, the equipment can begin operating immediately after connecting to water and power at the project site. This significantly shortens project preparation time, making it ideal for small-to-medium contaminated sites, multi-location remediation projects, emergency brownfield cleanup, and urban contaminated land restoration.

2. High-Efficiency Soil Washing for Multiple Contaminants

Equipped with Desen’s proprietary high-efficiency soil washing and separation technology, the system is capable of treating a wide range of contamination types, including:

• Heavy metal contamination

• Organic pollutants

• Complex mixed contamination

By combining customized washing agents with optimized process parameters, the system effectively removes contaminants such as lead (Pb), cadmium (Cd), chromium (Cr), arsenic (As), and other hazardous substances from contaminated soils.

Its multi-stage continuous washing process enables simultaneous soil feeding, chemical mixing, contaminant stripping, and clean soil separation. With a processing capacity of up to 200 cubic meters per day, the system can reduce remediation timelines by over 40% compared to traditional batch-processing equipment.

3. Smart Closed-Loop System for Sustainable Operation

The equipment is powered by a DCS distributed control system combined with 5G cloud connectivity, enabling both on-site and remote monitoring. Operators can track key parameters in real time, including:

• Washing efficiency

• Chemical concentration

• Wastewater quality

• Soil treatment performance

The system automatically adjusts operating parameters to ensure stable remediation performance while reducing chemical consumption and energy use.

A major innovation is Desen’s integrated intelligent closed-loop water treatment system, featuring a three-stage water recycling process (thickening → filter pressing → purification). More than 90% of process water is recycled and reused on-site, minimizing freshwater consumption and eliminating wastewater discharge, helping projects meet strict environmental compliance and green construction standards.

4. Safe, Durable & Built for Complex Conditions

To maximize operational safety, the equipment features a fully enclosed operating cabin and remote-control system, allowing operators to manage the remediation process without entering contaminated zones and minimizing exposure risks.

An integrated environmental monitoring and alarm system automatically activates emergency protection procedures if abnormal conditions are detected.

Built for demanding field environments, the unit uses special anti-corrosion coatings and temperature-resistant materials, ensuring stable performance in temperatures ranging from -25°C to 55°C. Its mobile chassis is designed for difficult terrain, including muddy construction sites and sloped mining areas, making it suitable for:

• Chemical and pharmaceutical contaminated sites

• Metallurgical and industrial brownfields

• Mining remediation projects

• River sediment treatment

• Tunnel slurry and drilling mud management
