When soil contamination caused by industrial legacy sites and agricultural non-point sources becomes a bottleneck restricting safe land use, Desen Environment’s soil washing equipment stands out as a benchmark solution in the remediation field. With its core strengths of efficient contaminant separation, green circular operation, and flexible deployment, it delivers practical and scalable solutions for a wide range of contaminated sites.
Targeted Remediation That Tackles Pollution at Its Source
Unlike traditional remediation methods that are time-consuming and lack precision, Desen’s soil washing equipment adopts an innovative “graded separation + targeted washing” process that directly addresses contamination at its core.
The system first uses multi-stage screening and hydrocyclone separation to classify soil by particle size, isolating fine particles where contaminants are most concentrated. Based on the specific pollution profile, customized washing agents are then applied. Through high-intensity agitation, contaminant stripping, and efficient solid–liquid separation, heavy metals and organic pollutants are rapidly removed from soil particle surfaces.
After treatment, the remediated soil meets safe utilization standards, significantly shortening remediation timelines and greatly improving overall efficiency.
Flexible Deployment for Diverse and Complex Site Conditions
Designed with modular flexibility, Desen’s soil washing equipment adapts seamlessly to a wide range of remediation scenarios. A single unit can independently complete the entire process—screening, washing, dewatering, and water treatment—making it ideal for small to medium contaminated sites. For large-scale or high-concentration pollution, multiple units can be operated in parallel, achieving exponential capacity expansion.
Compliant with road transportation standards, the system can be easily relocated via trailer towing. Whether addressing urban industrial brownfields, rural farmland contamination, or remote mining tailings sites, the equipment enables rapid installation, commissioning, and operation—truly delivering “site-independent, immediate remediation.”
Green Closed-Loop Operation with Intelligent Control
The equipment is integrated with a complete water treatment module, allowing wastewater generated during washing to be deeply purified and recycled back into the process, forming a closed-loop water system. Dewatered filter cakes can be safely backfilled or reused as resources according to regulatory standards, effectively preventing secondary pollution at the source.
An intelligent control system continuously monitors key parameters such as washing temperature, reagent dosage, and solid–liquid separation efficiency. Automated precision control reduces labor intensity while ensuring stable, consistent remediation results, embedding green and circular principles throughout the entire operation.
Proven Performance Across Thousands of Remediation Projects
From organic contamination treatment in chemical parks to heavy-metal remediation of agricultural land, Desen Environment’s soil washing equipment has demonstrated outstanding performance in thousands of real-world projects. By empowering soil remediation with advanced technology and professional expertise, Desen continues to restore land vitality and unlock sustainable value—injecting strong momentum into the renewal of contaminated soil and the future of green development.
