Resource Utilization of Waste Soil and Mud as Backfill Materials

2026-07-01

Silt and spoil from river dredging and foundation pit excavation face high transport costs, strict environmental rules and direct backfilling bans. The Ninon waste sludge solidification equipment uses integrated pre-crushing, mixing and screening workflows. This waste sludge solidification equipment standardizes treatment for wet dredged silt, mine mud cakes and organic soft soil to make qualified embankment backfill. All key operations of this waste sludge solidification equipment depend on tailored mixing modules, and this waste sludge solidification equipment acts as an all-in-one sludge recycling system.

Typical Process for Flowable Solidified Soil Treatment


The wet soil remediation equipment executes the entire dredged soil solidification workflow: stored silt is piston-pumped to stations, screened, dosed with curing agents and mixed, then cured for 3 days to meet embankment criteria. This wet soil remediation equipment handles compacted and high-organic soil via modular upgradable designs, and this wet soil remediation equipment adapts easily to diverse sludge feeds.
