Product DescriptionProduct Descriptionsludge dewatering machineOverlapping Screw Press: Sludge Dewatering SystemThis 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 FeedingSlurry is conveyed from sludge holding tanks to feed hoppers via progressive cavity pumpsIn-hopper agitators maintain homogeneous solids concentration (typically 0.5-2% TS)Polymer ConditioningAutomatic dosing systems prepare optimal flocculant solutions (e.g., cationic PAM)Precision metering pumps inject polymer into conditioning tanksFlocculation & SeparationTurbulent mixing induces alum-floc formation with embedded water releaseConditioned sludge enters overlapping screw assembly for progressive compressionDewatering & DischargeFiltrate discharges through moving ring gaps (60% water removal)Dewatered cake (18-25% DS) exits at terminal discharge chuteCyclic transport vehicles remove accumulated sludge cakesClosed-loop OperationReturn filtrate recirculates to headworks of wastewater treatment trainsContinuous feed/discharge enables 24/7 unmanned automationSpecificationModelLK-wnts5LK-wnts6Technical AdvantagesProcessing Capacity~10 m3/h~25 m3/hSelf-cleaning & clog-free design, maintenance-freeDry Solids Output100–150 kg-DS/h250–450 kg-DS/hTriangular rotor automatically conveys sludgeCake Moisture78–85%78–85%No backwashing needed, reduces energy consumption by 40%Power Supply3Φ 380V3Φ 380V24/7 continuous unmanned operationSludge dewatering machine products all-round displayOverlapping Screw Press: Technical Advantages1. Universal ApplicabilityIndustry Coverage: Papermaking, municipal WWTPs, food/beverage, chemicals, leather, welding materials, textiles, pharmaceuticalsSludge 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 generation2. Compact FootprintIntegrated Modules: Electrical cabinet, conditioning tank, flocculation mixer, press bodySpace Optimization: 30-50% smaller than belt pressesMaintenance Efficiency: Lightweight design (<800 kg) for easy transport Component accessibility for rapid replacement3. Anti-Clogging PerformanceSelf-Cleaning Mechanism:Zero manual screen cleaning60-70% reduction in rinse water consumption Prevents internal recirculation overloadOil-Sludge Competence: Handles greasy sludge with ≤15% lipid content4. Low-Speed OperationDrive System: 2-3 RPM spiral shaft rotationOperational Benefits: Power consumption <1.5 kW·h per ton DS Noise level ≤65 dB(A) at 1m distance Vibration amplitude <50 μm5. Automated ControlPLC Integration: Synchronizes sludge pumps, dosing systems, conveyors Enables 24/7 unmanned operationMaintenance Efficiency: Daily service <30 minutes Tool-free component access6. Robust ConstructionMaterial Integrity: 304/316L stainless steel bodyLifecycle Advantages: Service life >15 years Only wear parts: Spiral shaft & moving rings (replacement cycle >10,000 hrs)Application scope of stacked-screw sludge dewatering machineSludge Dewatering System: Application AdvantagesThis 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 reuseO&M cost savings of 30-40% vs. conventional systemsBefore and after sewage treatmentSludge Dewatering System Performance MetricsFeedstock Characteristics (Untreated Sludge)Visual Profile: Blackish-gray slurry with visible suspended solids (grease, food residues) and pungent odorCritical Contaminants:?
