How Oil Contaminated Soil Thermal Washing System Reduces Remediation Costs by 30%
Discover how Desen Environment's oil contaminated soil thermal washing system achieves over 90% water recycling and 30% cost reduction. Physical scrubbing technology for petroleum-contaminated sites with TPH up to 50,000 mg/kg.
Oil spills and petroleum-contaminated soil remain critical environmental challenges for oil fields, refineries, and industrial sites worldwide. Traditional remediation methods often require expensive chemical treatment or lengthy bioremediation cycles. Desen Environment has developed a proven oil contaminated soil thermal washing system that combines physical scrubbing with advanced separation technology to deliver fast, cost-effective remediation.
How the Thermal Washing Process Works
The system uses a multi-stage approach: pre-screening removes oversized debris, followed by rotary drum scrubbing with specialized washing agents to detach petroleum hydrocarbons from soil particles. The slurry then passes through hydro-vibrating screening for coarse-fine separation and enters a soaking and oil-water separation tank where oil scum is collected for hazardous waste disposal.
Key Performance Advantages
Processing capacity of 15–100 tons per hour with modular configuration
Closed-loop water recycling achieves ≥90% reuse rate, minimizing fresh water consumption
Plate-and-frame filter press delivers filter cake with moisture content under 40%
5G IoT remote monitoring enables real-time data oversight and automated operation
Recovered clean aggregate (0.15–2 mm sand) can be reused as construction backfill
Where This System Proves Most Effective
The thermal washing system is ideal for oil field spill sites, abandoned gas station leaks, petrochemical plant yards, and dockyard oil-contaminated zones. It handles soils with TPH levels up to 50,000 mg/kg. For sites exceeding this concentration, pre-treatment or staged processing is recommended.
With projects spanning the Middle East and China, Desen Environment's thermal washing equipment has treated over 2 million cubic meters of contaminated soil. The system's combination of modular design, rapid deployment, and low operating costs makes it a preferred choice for environmental remediation contractors seeking reliable oil contaminated soil treatment machines.
