Heavy metal contamination has become a global ecological challenge. From former industrial sites to agricultural land, from mining areas to urban plots, contaminated scenarios are increasingly complex, and the demand for efficient remediation solutions is urgent. With its integrated mobile design, multi-media washing adaptability, and closed-loop treatment system, the Desen Soil Washing Plant breaks traditional site limitations and demonstrates exceptional versatility across diverse contaminated environments—emerging as a true all-in-one solution for soil remediation.

Effective Remediation for Complex Industrial Contaminated Sites

Industrial sites such as chemical plants and smelters often suffer from long-term accumulation of heavy metals including cadmium, nickel, and arsenic. These pollutants penetrate deeply into heterogeneous soil layers, making remediation technically demanding and strictly regulated.
The Desen Soil Washing Plant can flexibly switch between water-based washing, inorganic solvents, or chelating agents, combining physical scrubbing with chemical washing to efficiently remove contaminants from soil particle surfaces.

In a contaminated soil remediation project at a steel plant in Jinan, the Desen system successfully achieved rapid compliance with heavy metal standards, while recovering over 90% of sand and aggregate for reuse. Thanks to its modular structure, the system requires no permanent infrastructure and can be rapidly installed and commissioned, significantly reducing project timelines.

Reliable Performance in Mining and Tailings Areas

Mining zones and tailings storage areas are among the most severely affected by heavy metal pollution. Open-pit mines, tailings ponds, and heap washing sites often face compounded risks such as slope instability and acidic wastewater contamination. The soil in these areas is typically clay-rich and difficult to treat, posing major challenges to conventional technologies.

With its strong adaptability to complex soil textures, the Desen Soil Washing Plant overcomes these limitations. In a tailings washing project at a mining site in Chengde, the system achieved flexible processing capacities ranging from 15 to 200 tons per hour, enabling efficient large-scale treatment. At the same time, its closed-loop system ensures centralized treatment of washing effluent, preventing acidic wastewater leakage and secondary pollution—addressing both environmental remediation and ecological safety.

Customized Solutions for Oil, Gas, and Special Contamination Scenarios

The Desen Soil Washing Plant also excels in oil and gas fields and other specialized contamination scenarios. In a petroleum hydrocarbon–contaminated soil remediation project in Ningxia, the system was configured with a customized process to simultaneously treat heavy metals and organic pollutants.

At electronic waste dismantling sites affected by mercury contamination, Desen’s precision washing technology converts insoluble mercury compounds into soluble forms. Combined with advanced wastewater treatment, this approach enables thorough contaminant removal and resource recycling.

From arid coal mining regions to humid agricultural land in southern China, from large industrial brownfields to small scattered plots, the Desen Soil Washing Plant delivers full scenario coverage and precise adaptability, building a diversified and scalable application ecosystem.

A Versatile Tool for Sustainable Soil Remediation

While contamination scenarios vary widely and remediation priorities differ, Desen continues to break through application barriers through technological innovation. The Desen Soil Washing Plant provides efficient, flexible, and environmentally friendly soil remediation solutions across industrial, mining, agricultural, and urban–rural environments.

By safeguarding ecological security and supporting the sustainable redevelopment of contaminated land, Desen has established its soil washing technology as a powerful and reliable solution for global heavy metal soil pollution control.
