Why Does the Deep-Cone Sedimentation Module in a Soil Washing System Require Flocculant?

In Desen’s soil washing system, coarse particles are first separated through scrubbing, screening, and hydraulic classification. The slurry entering the Deep-Cone Sedimentation Module therefore consists of selected fine particles.

This slurry typically contains a high proportion of fine particles. Gravity settling alone may not achieve the required balance between thickening efficiency, overflow water quality, and downstream filter press performance.

Therefore, an appropriate flocculant is generally added to promote particle aggregation and form larger flocs, improving settling performance and slurry thickening while providing suitable feed conditions for subsequent filter press dewatering.

Effective thickening is not just about settling solids. It is about preparing the slurry for efficient downstream dewatering.

Soil Scrubbing: Separating Contaminants, Not Breaking Soil

In soil washing, scrubbing is not simply about “washing soil” or “breaking soil into smaller particles.”
Its real purpose is to disrupt the bonding between contaminants and soil particles.
Through continuous particle-to-particle friction and collision, the drum scrubber removes surface coatings and clay films, promotes contaminant release, and creates better conditions for subsequent classification, extraction, and solid-liquid separation.
Desen Environment continues to advance soil washing technology, providing reliable and efficient equipment solutions for complex contaminated site remediation.

When contaminated land needs to be restored, every project demands a solution that is fast, flexible, and efficient.

Instead of transporting contaminated soil to an off-site treatment facility, Desen Environment's Mobile Soil Washing Plant brings the complete remediation process directly to the project site.

Our fully modular system integrates feeding, screening, scrubbing, classification, solid-liquid separation, and water treatment into trailer-mounted units. With rapid deployment and flexible relocation, it is an ideal solution for industrial sites, brownfield redevelopment, mining projects, and emergency environmental response.

Key Advantages

✅ Rapid deployment within 1–3 days

✅ Processing capacity of 10–15 T/H

✅ ≥90% water recycling rate

✅ Modular configuration for different project requirements

✅ Intelligent DCS + 5G IoT remote monitoring

More than just equipment, we provide complete project support—from process design and equipment manufacturing to commissioning, operator training, and after-sales service.

At Desen Environment, we believe that every successful remediation project begins with reliable technology and a dedicated team.

Together, we're making soil restoration more efficient, smarter, and more sustainable.

📩 Feel free to contact us to discuss your next soil remediation project.

From Landfills to Prime Land: Unlocking the Value of Contaminated Sites

What used to be “outskirts” landfills are now sitting in the heart of growing cities.
But here’s the challenge:
Many of these sites contain mixed waste — municipal, construction, and industrial — with little historical control, leading to long-term environmental risks:
▪ Leachate contaminating groundwater
▪ Methane and greenhouse gas emissions
▪ Residual heavy metals and organic pollutants
So how do we safely remediate and unlock land value?
Common Remediation Strategies
1.In-situ (Containment-based)
Best for risk control:
✔ Capping systems
✔ Landfill gas management
✔ Groundwater monitoring

2.Ex-situ (Excavation & Treatment)
Increasingly preferred for redevelopment projects:
Screening → Soil Washing → Targeted Treatment
Screening: separates waste and soil
Soil washing: reduces contaminated volume (key step)
Thermal desorption / S/S / Bioremediation: final polishing

Why Soil Washing Matters
In most cases, contaminants are concentrated in fine particles.
Soil washing enables:
✔ Significant volume reduction
✔ Lower overall remediation cost
✔ Higher material recovery
Modular soil washing systems (like Desen’s solutions):
Compact footprint
Fast deployment
Easy relocation
Ideal for multi-site operations
Industry Trends
✔From containment → redevelopment
✔From single solution → integrated systems
✔ From disposal → volume reduction & reuse
Landfills are no longer just liabilities —
they are opportunities for urban transformation.
