Traditional soil remediation methods—often dependent on fixed treatment facilities—are struggling to meet the demands of modern environmental governance. Large upfront infrastructure investments, long project timelines, and the risk of secondary pollution during long-distance soil transportation make conventional approaches inefficient, especially for complex sites such as former chemical plants, farmland near mining areas, and industrial contamination zones. In response to these challenges, Desen Environment’s self-developed mobile soil washing plant delivers a breakthrough solution, bringing high-efficiency remediation directly to contaminated sites.

This fully integrated mobile system combines soil screening, contaminant washing, solid–liquid separation, and wastewater recycling into a single, transportable unit. Without the need for permanent infrastructure, the soil washing plant can be rapidly deployed to various contaminated locations, enabling immediate on-site treatment. For different types of heavy metal contamination, customized washing agents are precisely formulated and applied through high-pressure spraying to effectively remove hazardous elements such as lead, cadmium, chromium, and arsenic from soil particles.

An onboard wastewater treatment system utilizes multi-stage filtration and chemical precipitation, achieving over 90% water reuse. Treated water is directly recycled back into the washing process, effectively eliminating wastewater discharge and preventing secondary pollution at the source.

To ensure consistent remediation quality, the system is equipped with an intelligent monitoring module that continuously tracks washing efficiency and contaminant concentrations. Processing parameters are adjusted in real time to ensure that remediated soil meets safety and regulatory standards. Operators manage the entire process through a centralized control interface, significantly reducing labor costs and operational errors.

Whether addressing urgent brownfield remediation in densely populated urban areas or restoring contaminated farmland in remote rural regions, Desen’s soil washing plant enables on-site remediation and rapid demobilization. This mobile approach shortens project timelines and reduces overall remediation costs while minimizing disruption to surrounding environments.

In real-world applications, the advantages are clear. At a former electroplating facility with severe heavy metal contamination, traditional remediation plans required months of work and costly temporary facilities. Desen’s soil washing plant completed the entire project in just 20 days, with post-treatment soil contaminant levels well below national standards, allowing the site to be successfully converted into urban green space. In agricultural remediation projects near mining areas, the equipment operates directly in the fields without altering landform structures, enabling farmers to resume cultivation quickly and safeguarding agricultural livelihoods.

As environmental protection enters a new era, soil remediation has become both a critical responsibility and a complex challenge. With its mobile design, innovative technology, and proven performance, Desen Environment’s soil washing plant is redefining how contaminated land is restored—reviving damaged soils, supporting sustainable land use, and delivering measurable environmental and economic value.
