Learn how mobile screening plants support contaminated soil remediation. Desen Environmental mobile screening equipment delivers efficient material pre-treatment and classification.

Pre-treatment and material classification form the foundation of any successful contaminated soil remediation project. A mobile screening plant provides the critical first-stage processing that separates oversized debris, homogenizes feed material, and protects downstream remediation equipment from damage and blockages.

The Role of Screening in Soil Remediation

Contaminated soil arriving at a treatment site rarely arrives in a uniform, process-ready condition. Excavated material typically contains construction debris, rock fragments, organic matter, and soil aggregates of widely varying sizes. Without proper screening, these inconsistencies cause feed rate fluctuations, equipment clogging, and uneven treatment results. A mobile screening plant addresses these challenges at the project entry point, ensuring consistent material flow to washing, bioremediation, or stabilization units.

Desen Environmental's DS15SE mobile screening plant is a tire-mounted, two-deck heavy-duty screener designed for soil remediation and solid waste processing applications. With a processing capacity of 60 to 200 tons per hour and customizable screen apertures (2cm, 3cm, 4cm, 6cm, and other specifications), it delivers precise three-tier classification across diverse material types.

Technical Specifications and Design Features

The DS15SE mobile screening plant integrates several design features that enhance reliability in demanding field conditions:

• Two-deck screen configuration: Separates input material into three size fractions in a single pass, maximizing classification efficiency.
• Variable inclination (14°–20°): Adjustable screen box angle optimizes material retention time and throughput for different soil types.
• High-performance elastic vibration supports: Reduce structural stress and noise while maintaining stable vibration characteristics.
• Seamless vulcanized rubber conveyor belts: Five-layer nylon construction with continuous forming eliminates joint failure points.
• Maximum feed size 150mm: Accepts a wide range of excavated material without upstream crushing.
• Total weight 13,500 kg: Standard trailer-towable configuration enables rapid site-to-site relocation.

Applications Across Remediation Project Types

In soil remediation projects, the mobile screening plant serves multiple functions beyond simple size classification:

Soil Homogenization for Bioremediation

At a bioremediation project in Ningxia, China, the DS15SE provided all-site contaminated soil homogenization pretreatment. Biological treatment methods require strict control over soil particle size distribution and material uniformity to achieve consistent microbial activity. The mobile screening plant removed oversize debris, broke down soil clods, and delivered homogenized material that enabled stable bioremediation performance throughout the project duration.

Pre-Processing for Soil Washing Lines

Across multiple remediation projects in Chongqing and Nanjing, mobile screening plants operated as the front-end core equipment for soil washing production lines. By pre-screening contaminated soil to remove rocks, construction waste, and large aggregates, the unit prevented downstream scrubbing and classification equipment from experiencing blockages and load fluctuations. This protection significantly improved the continuity and stability of the entire treatment line.

Landfill Mining and Resource Recovery

At a landfill mining and waste resource recovery project in Shenzhen, the mobile screening plant processed legacy landfill material with complex composition—plastics, films, boulders, sand, gravel, and soil fractions. The two-deck configuration achieved efficient separation of these diverse components, enabling solid waste volume reduction, material sorting, and aggregate recovery. The project demonstrated how mobile screening technology supports the goals of reduction, harmless treatment, and resource recovery in landfill remediation scenarios.

Why Mobile Configuration Matters

Fixed screening installations involve civil foundation work, lengthy setup periods, and limited reusability across projects. A mobile screening plant mounted on a trailer chassis eliminates these constraints. The DS15SE unit operates with a total installed power of just 28.5 kW and compact transport dimensions of 9,600 × 3,100 × 3,330 mm, making it practical for multi-site contractors who need equipment that moves with the project pipeline.

For contaminated soil remediation contractors and environmental engineering firms, integrating a mobile screening plant into the treatment workflow represents a practical investment in process reliability, material quality control, and operational flexibility across diverse site conditions.
