Slurry Treatment System: Transforming Municipal Sludge into Reusable Resources
Desen Environment's slurry treatment system achieves ≥95% aggregate recovery and fully recycled wastewater for municipal sludge, river sediment, and shield tunneling slurry. Modular design with 5–100 t/h capacity.
Municipal pipe network dredging, river sediment cleanup, and shield tunneling operations generate enormous volumes of slurry that present significant disposal challenges. Desen Environment's multi-type slurry treatment system offers a complete solution — achieving volume reduction, harmless treatment, and resource recovery in a single integrated process.
Complete Processing Flow for Maximum Recovery
The system begins with rotary drum scrubbing for 20 mm coarse separation of debris and organics. Hydro-vibrating screening then classifies material at 2 mm, followed by multi-stage flotation and classification to separate reusable sand (0.075–2 mm) from fine silt. A deep cone thickener concentrates the remaining slurry before the plate-and-frame filter press produces low-moisture filter cakes suitable for construction use.
Measurable Performance Outcomes
Aggregate recovery rate: ≥95% — maximizing reusable material output
Filter cake moisture content: ≤40% — ready for transport and reuse
Wastewater treatment: 100% recycled through PAC/PAM/H₂O₂ multi-stage purification
Processing capacity: 5–100 t/h (stationary) or ≤15 t/h (mobile truck-mounted)
Recovered sand purity: up to 92% — suitable for construction aggregate
Real-World Application Success
In a Guangzhou municipal project, Desen's slurry treatment system processed over 300 tons of pipe network sludge in just two weeks — half the originally projected timeline. The system recovered reusable sand and gravel with 92% purity, dramatically reducing the volume requiring off-site disposal. Similar results have been achieved in river silt remediation, shield tunneling slurry projects, and culvert desilting operations.
The modular design allows rapid assembly on-site, while the 5G cloud IoT monitoring platform provides real-time data on slurry separation efficiency, water quality parameters, and equipment status. For municipalities and contractors facing growing sludge management challenges, Desen Environment's slurry dewatering equipment provides a proven path from waste to resource.
