Across urban redevelopment sites, scattered rural contamination zones, and ecologically sensitive riverbank areas, soil remediation faces unique on-site challenges — limited space, poor accessibility, or the risk of secondary pollution. DESEN Environmental’s Soil Washing plant breaks free from the limitations of “one-size-fits-all” equipment design. With scenario-specific customization as its foundation and intelligent technology as its core, it offers a breakthrough solution for diverse and complex soil restoration needs.

Scenario-Based Design: Tailored for Every Environment

At the heart of the innovation lies its customized, scenario-oriented design.

For high-value urban redevelopment sites — such as commercial complexes surrounded by aging infrastructure — the plant features a telescopic operation arm and compact modular structure, allowing flexible operation in confined spaces. The sealed washing process prevents dust and chemical volatilization, cutting remediation time by up to 40% compared to traditional methods, perfectly aligning with the fast-paced demands of urban construction.

For rural pollution sites like abandoned farms or small contaminated plots, the mobile unit can travel directly to the site via local roads, operating independently without the need for fixed infrastructure. Powered entirely by its onboard energy system, it can restore land that’s later converted into farmland or community spaces.

In riverbank and wetland zones, where ecosystems are highly sensitive, the plant can switch between different washing processes to tackle salinization and heavy-metal pollution simultaneously — improving soil composition, stripping contaminants, and restoring ecological balance. After treatment, vegetation is planted to create a natural buffer zone, enhancing riverbank stability while promoting biodiversity.

Intelligent and Circular Technology: Smarter, Cleaner, More Sustainable

The system integrates a 5G-enabled intelligent cloud management platform that supports remote control and real-time monitoring via both PC and mobile devices. On-site sensors analyze pollutant concentration and automatically adjust washing parameters for optimal efficiency. For complex cases involving combined contamination (such as heavy metals and PAHs), the automated reagent system switches modes to first degrade organics, then immobilize heavy metals — ensuring thorough treatment.

Equally impressive is its closed-loop resource recovery system:

Wastewater from the washing process undergoes multi-stage purification — sedimentation, filtration, and reuse — achieving over 90% recycling efficiency. Separated sand and gravel are recovered for direct reuse, while fine-grained soils that meet safety standards can be safely backfilled, truly realizing “reduction, detoxification, and resource reuse.”

From Equipment to Ecosystem Solution

Today, DESEN’s Soil Washing plant has evolved beyond a single-purpose machine — it serves as a bridge linking pollution control, land reuse, and ecological enhancement.

In cities, it transforms old industrial zones into innovation hubs, breathing new economic vitality into idle land.

In rural areas, it restores farmland and strengthens the foundation for food security and sustainable agriculture.

In eco-sensitive regions, it combines soil restoration with vegetation recovery, creating green barriers that protect biodiversity.

From technological innovation to real-world transformation, DESEN Environmental’s Soil Washing plant embodies a site-specific remediation philosophy — providing scalable, replicable, and sustainable soil health solutions for different environments. It stands as a practical force driving both ecological restoration and socio-economic progress.
