Product Description

Product Description

sludge dewatering machine

Overlapping Screw Press: Sludge Dewatering System

This robust dewatering technology is extensively implemented in papermaking effluent systems, municipal WWTPs, and industrial sectors including petrochemicals, light industry, chemical fibers, pharmaceuticals, and leather processing. Field verifications confirm significant economic returns and environmental benefits for operators.

Process Workflow:

Sludge Feeding

Slurry is conveyed from sludge holding tanks to feed hoppers via progressive cavity pumps

In-hopper agitators maintain homogeneous solids concentration (typically 0.5-2% TS)

Polymer Conditioning

Automatic dosing systems prepare optimal flocculant solutions (e.g., cationic PAM)

Precision metering pumps inject polymer into conditioning tanks

Flocculation & Separation

Turbulent mixing induces alum-floc formation with embedded water release

Conditioned sludge enters overlapping screw assembly for progressive compression

Dewatering & Discharge

Filtrate discharges through moving ring gaps (60% water removal)

Dewatered cake (18-25% DS) exits at terminal discharge chute

Cyclic transport vehicles remove accumulated sludge cakes

Closed-loop Operation

Return filtrate recirculates to headworks of wastewater treatment trains

Continuous feed/discharge enables 24/7 unmanned automation

Overlapping Screw Press: Technical Advantages

1. Universal Applicability

Industry Coverage: Papermaking, municipal WWTPs, food/beverage, chemicals, leather, welding materials, textiles, pharmaceuticals

Sludge Concentration Flexibility:

Processes both high/low solids sludge (2,000 mg/L to 50,000 mg/L)

Eliminates thickening tanks for dilute sludge (<5,000 mg/L), reducing:

 Capital costs by 25-40%

 Phosphorus release risk

 Anaerobic odor generation

2. Compact Footprint

Integrated Modules: Electrical cabinet, conditioning tank, flocculation mixer, press body

Space Optimization: 30-50% smaller than belt presses

Maintenance Efficiency:

 Lightweight design (<800 kg) for easy transport

 Component accessibility for rapid replacement

3. Anti-Clogging Performance

Self-Cleaning Mechanism:

Zero manual screen cleaning

60-70% reduction in rinse water consumption

 Prevents internal recirculation overload

Oil-Sludge Competence: Handles greasy sludge with ≤15% lipid content

4. Low-Speed Operation

Drive System: 2-3 RPM spiral shaft rotation

Operational Benefits:

 Power consumption <1.5 kW·h per ton DS

 Noise level ≤65 dB(A) at 1m distance

 Vibration amplitude <50 μm

5. Automated Control

PLC Integration: Synchronizes sludge pumps, dosing systems, conveyors

 Enables 24/7 unmanned operation

Maintenance Efficiency:

 Daily service <30 minutes

 Tool-free component access

6. Robust Construction

Material Integrity: 304/316L stainless steel body

Lifecycle Advantages:

 Service life >15 years

 Only wear parts: Spiral shaft & moving rings (replacement cycle >10,000 hrs)

Application scope of stacked-screw sludge dewatering machine

Sludge Dewatering System: Application Advantages
This adaptive dewatering technology specializes in treating high-organic, lipid-rich sludge from municipal WWTPs, food processing, textile dyeing, and related industries. Particularly engineered for decentralized wastewater treatment scenarios in townships and villages, it delivers a cost-effective sludge management solution achieving:
Volume reduction ≥60%
Biosolids recovery for agricultural reuse
O&M cost savings of 30-40% vs. conventional systems

Before and after sewage treatment

Sludge Dewatering System Performance Metrics

Feedstock Characteristics (Untreated Sludge)

Visual Profile: Blackish-gray slurry with visible suspended solids (grease, food residues) and pungent odor

Critical Contaminants:
• COD > 500 mg/L
• BOD5 > 200 mg/L
• NH3-N > 30 mg/L

Ecological Risk: Direct discharge causes eutrophication, algae blooms, and aquatic ecosystem collapse

Post-Treatment Output

Effluent Quality: Colorless transparent liquid, >95% SS removal, odor-free

Regulatory Compliance:
• COD < 50 mg/L
• BOD5 < 10 mg/L
• NH3-N < 5 mg/L
› Fully meets GB 18918-2002 Class 1A discharge standards

Environmental Impact: Safe for discharge with negligible ecological disturbance
