Product Overview
The Sludge Thickening Centrifuge is a horizontal decanter centrifuge for concentrating dilute sludge before dewatering or anaerobic digestion. It is intended for feed sludge with solids concentrations of approximately 0.5%–1%.
Sludge Thickening Applications
Municipal Wastewater
Thickens waste activated sludge (WAS) before anaerobic digestion, reducing sludge volume and increasing solids concentration for digestion.
Food and Beverage
Concentrates organic and biological sludge before mechanical dewatering, reducing dilute sludge volume entering the dewatering stage.
Paper and Pulp
Thickens fiber-rich sludge before dewatering, removing excess water and reducing the volume of solids for handling.
Chemical Processing
Concentrates chemical process sludge and fine suspended solids before dewatering, reducing liquid load on downstream equipment.
Machine Configuration
High-Speed Bowl and Screw Conveyor
The bowl provides centrifugal separation while the screw continuously conveys concentrated solids to the discharge outlet.
Differential Gearbox
Controls the speed difference between the bowl and screw to regulate solids conveying and discharge.
Dual-Frequency Drive
Provides independent, stepless control of bowl speed and differential speed for separation and solids discharge adjustment.
PLC Control
Monitors and controls the main operating parameters. The screw structure reduces material slippage during biological sludge conveying.
FAQ
1. What should be included in the purchase order?
Specify the equipment configuration, material grade, electrical standard, process connections, accessories, documents, and supply scope.
2. How is a replacement project evaluated?
Provide the existing model, nameplate data, drawings, connections, sludge data, and operating records.
3. Is a complete skid package available?
The skid package includes the centrifuge, feed pumps, and polymer dosing equipment.
4. How are changes handled after quotation?
Changes to capacity, materials, electrical requirements, installation, controls, or accessories are recorded in the revised specification before order confirmation.
5. How is the export supply scope confirmed?
The quotation and purchase order list equipment, accessories, documents, tools, and shipping requirements separately.
6. What site information is required before shipment?
Provide the installation location, lifting access, feed and discharge connections, electrical supply, drainage, and installation access.
7. How are spare parts specified?
Spare parts are listed by equipment configuration and component, with required site-stock quantities confirmed in the order.
8. How are repeat orders controlled?
Previous approved specifications, drawings, configurations, and inspection records are used as the reference for repeat orders.
9. What after-sales support is included?
Commissioning and operator training cover operation, safety, maintenance, and basic fault diagnosis. The warranty is one year from qualified commissioning, with an initial response within 2 hours for product quality issues.
