In the era of heightened focus on soil pollution governance, Desen Environment's oil-contaminated soil washing equipment has emerged as a leading solution, delivering high-efficiency remediation through its cutting-edge technology.
Core Technology: Innovative Washing Process
The equipment's competitive edge lies in its advanced chemical/biochemical washing process. Specialized solvents act as precise "detergents," penetrating soil pores to interact with petroleum pollutants. Driven by gravity or hydraulic pressure, these solvents strip and dissolve stubborn contaminants from soil particle surfaces. Rigorously tested and optimized, this process demonstrates remarkable effectiveness against various petroleum pollutants.
Smart Control: 5G Intelligence & PLC System
Equipped with a "smart brain" via 5G intelligent modules and a PLC control system, the equipment monitors over 200 operational parameters in real time—from washing liquid ratios, temperature/pressure settings, to soil processing speed. With a material measurement error ≤0.5%, it ensures precise reagent dosing for stable, high-efficiency performance. The system supports 24/7 continuous operation, significantly enhancing productivity.
Integrated Modular Design
The modular architecture boosts adaptability:
Feeding Module: Rapidly transports contaminated soil to the treatment system.
Scrubbing Module: Utilizes special mechanical structures to remove pollutants.
Sorting Module: Precisely separates soil by particle size and contamination level.
Concentrating Module: Processes treated materials for recycling.
This design shortens debugging cycles by >50% compared to traditional equipment, while eliminating secondary pollution risks from soil transportation.
High-Performance Capabilities
Removal Efficiency: Achieves >90% petroleum hydrocarbon removal rate, with 30-40% higher processing efficiency than conventional equipment.
Versatility: Applicable to petroleum, chemical, pharmaceutical, and mining sectors, including special cases like trench sludge and river silt.
Mobility: Compact design enables operation in complex terrains (mountains, wetlands), overcoming accessibility limitations of traditional equipment.
Eco-Friendly & Energy-Saving Design
Waste Treatment: Wastewater undergoes multi-stage filtration and biodegradation for compliant discharge; exhaust gases are purified via adsorption and catalytic combustion.
Energy Optimization: Hierarchical heating with waste heat recovery reduces energy consumption by 40%, with 85% heat reuse efficiency.
Resource Recycling Value
The equipment recovers oil from oily sludge for refining, creating a "pollution control-recycling-value addition" closed loop that generates economic benefits while minimizing environmental impact.
Case Studies: Global Application Excellence
1. Ningxia Changqing Oilfield Project (China)
Facing extensive, deeply contaminated soil with complex pollution profiles, Desen's equipment employed a hierarchical treatment strategy:
Coarse particles were separated and pre-washed via the sorting module.
Fine-textured loam/clay underwent deep remediation.
After multiple washing cycles, petroleum hydrocarbons and heavy metals were effectively removed, with treated soil meeting all regulatory standards—winning high client approval.
2. UAE Oil Contamination Remediation Project
Confronting calcium-rich sand and extreme temperatures (-5°C to 50°C), Desen collaborated locally to develop a "step-scrubbing-cyclone sorting" process, integrating phase-change material temperature control. Key results:
Petroleum hydrocarbon removal rate: 92.3%
Sludge dewatering rate: ≥85%
Measurement accuracy: error ≤0.5%
This showcase of Chinese intelligent manufacturing met rigorous international standards.
As environmental policies tighten and soil remediation demands grow, Desen's soil washing equipment—backed by innovative technology and reliable quality—safeguards oil-contaminated soil projects worldwide. Join us in protecting soil health and creating a green future.
