Sludge Dewatering Equipment
Multi-Disc Sludge Dewatering Machine
Multi-disc sludge dewatering machine for continuous thickening and dewatering of flocculated sludge using a low-speed screw and self-cleaning fixed and moving disc stack. Final capacity and cake performance depend on sludge testing and operating conditions.
Overview
The Multi-Disc Sludge Dewatering Machine combines sludge thickening and mechanical dewatering in a compact continuous process. Conditioned sludge passes through a drum formed by fixed and moving discs while a low-speed screw conveys and compresses the solids toward the cake outlet.
Working Principle
Sludge is mixed with a suitable polymer in the flocculation section so stable flocs can enter the dewatering drum.
Free water drains through the disc gaps in the thickening zone before the screw gradually increases compression toward the discharge end.
Filtrate is collected separately while the dewatered sludge cake is discharged for conveying, storage, or downstream disposal.
Key Benefits
Relative movement between fixed and moving discs continuously clears the filtration gaps, helping reduce clogging and wash-water demand.
Low-speed continuous operation supports compact installation, reduced noise, and automated sludge-handling duties.
Suitable for appropriately conditioned biological sludge, DAF float, and selected industrial wastewater sludges after application testing.
Selection Information Required
Please provide sludge source and type, feed flow, inlet solids concentration, dry-solids load, operating hours, target cake solids, polymer information, available wash water, filtrate routing, material requirements, and installation limits. Final model selection and performance expectations must be confirmed through sludge data and, where necessary, a dewatering test.
