In the field of soil remediation, the Desen Environmental Integrated Soil Washing System has become a benchmark solution for heavy metal-contaminated soil and complex contaminated site remediation. Built around a modular integrated design, the system overcomes the deployment limitations of traditional fixed equipment and delivers fast, efficient, and flexible remediation for contaminated land projects.
As the 10th-generation upgraded solution, the equipment combines over 30 years of manufacturing expertise with advanced environmental engineering technology. Core process units—including screening, soil washing, solid-liquid separation, and wastewater recycling—are standardized into modular components, enabling a “transport, assemble, and operate immediately” deployment model that significantly shortens project timelines.
Modular Design for Flexible Soil Remediation
One of the system’s greatest advantages is its high adaptability to different project requirements. Equipment modules can be flexibly configured based on:
Site size and contamination scale
Soil composition and particle characteristics
Project treatment capacity requirements
For smaller contaminated sites, a compact setup ensures efficient use of space and lower operational costs. For large-scale remediation projects, multiple modules can operate simultaneously, with a processing capacity of up to 100 tons per hour, meeting the demands of industrial-scale soil treatment.
This flexibility makes the system suitable for a wide range of applications, including:
Heavy metal-contaminated land remediation
Industrial brownfield redevelopment
Mining site restoration
Complex mixed-contaminant soil treatment
Closed-Loop, Eco-Friendly Operation
Designed with sustainability in mind, the entire remediation process operates within a fully enclosed system, minimizing dust emissions and environmental impact.
An integrated closed-loop water recycling system enables over 95% wastewater reuse, drastically reducing freshwater consumption while preventing wastewater discharge and secondary pollution.
For heavy metal contamination, the equipment uses a multi-stage soil washing process to accurately separate harmful contaminants while preserving the soil’s natural structure. After treatment, cleaned soil can often be reused for backfilling, landscaping, or other resource recovery applications, supporting sustainable land redevelopment.
Low Maintenance & Cost-Effective Performance
The Desen Integrated Soil Washing Equipment is engineered for simple operation and low maintenance requirements. Its organized structural layout allows easy inspection and maintenance, reducing downtime and minimizing labor costs.
The compact system footprint makes installation practical even in urban redevelopment sites, abandoned industrial land, and space-constrained remediation areas, helping accelerate land reuse and environmental restoration projects.
Proven Technology for Global Soil Remediation Projects
From supporting China’s first 100-ton-scale heavy metal soil remediation project, to contributing to industry soil washing standards, and serving oil-contaminated land remediation projects in the Middle East, Desen Environmental has demonstrated its technical expertise across both domestic and international markets.
More than just a remediation machine, the Desen Integrated Soil Washing System represents a complete “pollution reduction – resource recovery – land reuse” philosophy. By transforming contaminated land into reusable resources, it provides an efficient, economical, and sustainable solution for modern soil remediation challenges.
