Hesaide River Dredging Sludge Treatment System

River Dredging Sludge treatment

Project address: Hebei

Category: River Dredging Sludge treatment

Common models: SDZ250/1250-30U、 SDZ500/1500-30U

1. Project Background

???? Location: River dredging project (urban/rural)
???? Challenge: Efficient silt dewatering with space constraints and eco-friendly disposal
???? Solution: Vehicle-mounted filter press system for on-site sludge treatment

2. Process Flow

Step 1: Silt Extraction & Pre-Treatment

• Dredging: Hydraulic pump extracts silt from riverbed

• Vibrating Screen: Removes debris >0.5mm (stones, branches, trash)

• Slurry Storage: Screened sludge stored in buffer tank

Step 2: Chemical Conditioning

• Polymer Dosing: Flocculant (PAM) added to enhance solid-liquid separation

• Mixing Tank: Ensures uniform flocculation

Step 3: Filter Press Dewatering

• Vehicle-Mounted Filter Press:

• Fast filtration & solidification (cycle time: 30-60 min)

• Low-moisture cakes (≤60%) – suitable for brick-making or landfill

• Clean Water Discharge:

• TSS <50mg/L → Safe for rainwater pipes or river return

Step 4: Mud Cake Reuse

• Construction Material: Mixed with cement for road base/bricks

• Landfill Cover: Alternative to soil

3. Key Equipment

4. Performance Data

✔ Processing Capacity: 50–100 m³/day (depending on silt density)
✔ Cake Moisture: 55–60% (can reach 50% with diaphragm squeeze)
✔ Water Clarity: TSS <30mg/L, pH 6–8 (meets GB 8978-1996 discharge standards)
✔ Energy Use: Low power consumption (7.5kW motor)

5. Advantages of Mobile System

✅ No Fixed Infrastructure – Ideal for remote/riverbank sites
✅ Fast Deployment – <4 hours setup time
✅ Zero Secondary Pollution – Closed-loop water recycling
✅ Cost Savings – 60% lower transport costs (vs wet sludge hauling)

6. Economic & Environmental Benefits

???? Cost Comparison:

???? Sustainability:

• 100% water recovery (reused or safely discharged)

• Mud cake recycling reduces landfill demand

???? Interested in this solution? Provide:

7. FAQ

Q: Can it handle high-organic silt?
A: Yes, with adjusted polymer dosing (anionic PAM recommended).

Q: What’s the minimum site area needed?
A: 10×20m for full setup (smaller if using elevated filter press).

Q: How to prevent filter cloth clogging?
A: Automatic cloth washing system (standard in our units).
