Oil contamination remains one of the most persistent environmental challenges left behind by industrial development. From leaks and overflows during oilfield extraction to accidental spills in chemical storage and transportation, petroleum hydrocarbons gradually infiltrate soil structures, disrupt soil stability, suppress microbial activity, and ultimately threaten groundwater safety and agricultural productivity.
Against this backdrop, Desen leverages its expertise in environmental equipment engineering to deliver innovative, customized solutions for oil-contaminated soil remediation—restoring polluted land and safeguarding ecological balance.
Flexible Ex-Situ Soil Washing Technology with Closed-Loop Operation
Unlike conventional remediation methods that are often inefficient and environmentally burdensome, Desen centers its solutions on ex-situ soil washing technology, creating a remediation system that combines flexibility, efficiency, and environmental responsibility.
Desen’s core equipment adopts a modular and integrated design, eliminating the need for permanent treatment plants. Plants for soil pre-treatment, washing separation, and solid-liquid purification are integrated and can be flexibly configured according to site conditions. During operation, contaminants are precisely separated from soil particles, while a closed-loop resource recycling system enables washing water to be reused and extracted pollutants to be centrally treated—effectively preventing secondary pollution at the source.
Customized Solutions for Diverse Oil Pollution Scenarios
Recognizing that oil contamination varies significantly by site, Desen provides scenario-specific remediation strategies:
Large-scale, high-concentration contaminated sites such as oilfields and refineries are addressed through parallel modular operations, forming high-capacity remediation lines for efficient centralized treatment.
Small, scattered contamination sites like gas stations and fuel storage depots are served by compact systems such as mobile soil washing Plants, allowing rapid deployment without extensive infrastructure and fast on-site remediation.
For complex combined pollution involving petroleum hydrocarbons and heavy metals, Desen upgrades functional modules to enable synergistic removal of multiple contaminants—overcoming the limitations of single-technology solutions.
Proven Performance Across Global Projects
Desen’s oil-contaminated soil remediation solutions have been successfully implemented across diverse regions and conditions. In oilfield sites, the equipment effectively treats clay-rich soils that are traditionally difficult to remediate, restoring soil permeability and vitality. At decommissioned urban gas stations, precision operations minimize environmental disturbance and ensure compatibility with surrounding commPlanties. In overseas projects, Desen’s adaptable systems and reliable remediation outcomes have earned strong recognition in international markets.
Driving Sustainable Remediation Through Innovation
Driven by innovation and guided by environmental responsibility, Desen continues to advance remediation technologies through continuous R&D and equipment upgrades. By promoting oil-contaminated soil remediation toward greater efficiency, sustainability, and intelligence, Desen remains committed to protecting ecosystems and supporting the long-term recovery of polluted land worldwide.
