Mobile Soil Washing Equipment for Rapid Emergency Remediation
Why Emergency Sites Need Mobile Soil Washing
Oil spills, leaking storage tanks and sudden discoveries of contaminated soil demand fast responses. Fixed plants can take months to build, but mobile soil washing equipment can be delivered to site and started within days, making it a practical choice for emergency and short-window remediation projects.
Design Built for Rapid Deployment
Desen's mobile washing platforms are trailer-mounted or skid-mounted so that feeding, scrubbing, classification, dewatering and water treatment modules travel together. The modular layout requires no heavy foundation; units are connected quickly and can be commissioned within about 15 days under normal conditions, while some compact configurations start operation within 24 hours of arrival.
Core Modules on a Single Platform
- Feeding and screening module with variable-speed belt for even feed
- Rotary attrition scrubber that breaks oil films and soil aggregates
- Hydraulic screen and classifier separating fine sand from sludge
- Deep cone thickener and filter press for dewatering
- Water treatment and recycling system with recycling rates over 90%
Proven in the Field
In Wenzhou, a 15 TPH mobile line treated lead- and arsenic-contaminated soil, while in Beijing a mobile washing vehicle performed ex-situ chemical washing of arsenic-contaminated soil. In the Middle East, a DS-MSW-100 mobile plant processed around 100,000 tonnes of oil-contaminated soil at a capacity of 100 t/h, recovering about 5,000 tonnes of crude oil and reducing hydrocarbon content to below 2,000 mg/kg.
Operational Advantages
- PLC or DCS control for consistent operation with a small crew
- Low energy consumption through variable-frequency drives
- Wastewater recycled and reused on site
- Easy relocation between multiple contaminated plots
Conclusion
When time is the biggest constraint, mobile soil washing equipment turns a contaminated site into a manageable operation quickly and safely. Whether the project involves a pipeline spill, a decommissioned industrial plot or multiple scattered parcels, a mobile plant can be scaled to the soil volume and contaminant type.
