Amid rapid urbanization, tunnel boring, metro construction, foundation pit excavation, river dredging and other municipal projects generate large volumes of sludge and massive amounts of construction muck.The filter cake produced after dewatering, in particular, features high moisture content, strong viscosity and certain pollutant characteristics.It occupies large land areas and entails high disposal costs, becoming a “burden on cities” that plagues numerous project managers and engineering contractors.
Pain Points of Traditional Treatment
● Land Occupation
Muck andfilter cakes have nowhere to be stacked, occupying a huge amount of land resources.
● Environmental Pollution
Wind and rain lead to secondary pollution, failing to meet environmental protection requirements.
● High Cost
High off-site transportation costs; compliant disposal sites are scarce and prices keep rising.
● Outdated Technology
The traditional lime-mixing and air-drying method features long cycles, unstable performance, and high dependence on weather conditions.
How can We Turn this Burden into Immediately Usable Resources?
NinonTech provides a disruptive solution.
Core Advantages of Our Equipment:
✔ Industry-leading stabilization and solidification for lumpy, high-moisture and viscous materials!
✔ Making lime treatment simpler, more efficient and eco-friendly!
✔ All-in-one solution: mechanical dewatering & viscosity reduction → sanding treatment →
particle size control (90% below 10mm) → maturation → roller-compacted solidified soil or fluidized soil construction.

Waaste Sludge Solidification Equipment
The "Transformer" on Construction Sites
This integrated waste sludge solidification equipment developed by NinonTech is specially designed for treating high‑moisture and high‑viscosity muck. It is not just a simple mixer, but an intelligent production line for reshaping the value of construction muck.
The waste sludge solidification equipment can convert troublesome high‑moisture, fluid‑plastic muck (with moisture content up to 30%–50%) on-site and rapidly into stable, ready‑to‑use high‑quality engineering fill material, realizing the resource utilization of waste sludge efficiently.
Core Breakthrough: A Technological Leap from "Sludge" to "Material"
1. Targeted & Precise Solutions
Muck from different sources (construction spoil, shield muck, dewatered mud cake) varies in moisture content, impurities and treatment difficulties. Our waste sludge solidification equipment first uses an integrated high‑efficiency crushing and homogenization module to break the original structure of mud cake, laying a solid foundation for uniform improvement.
2. Combined Physico‑Chemical Improvement
The waste sludge solidification equipment integrates an intelligent batching system for accurate dosing of quicklime‑based, gypsum‑based, solid‑waste‑based geopolymers and special eco‑friendly curing agents. Through powerful mechanical shearing and mixing, the curing agent fully contacts and reacts with soil particles, fundamentally improving the engineering properties of the soil.
3. Performance Upgrade – Proven by Data
After treatment by the waste sludge solidification equipment, the muck achieves a qualitative improvement:
(1)Moisture Content: Reduced from 30%–50% to an optimal 15%–20%, immediately meeting compaction construction requirements.
(2)Strength: 7‑day unconfined compressive strength reaches 0.8–2.5 MPa, fully satisfying bearing capacity requirements for subgrade and backfilling.
(3)CBR Value: California Bearing Ratio (CBR) increased from below 2% to over 8%, meeting standard specifications for subgrade subbase.
(4)Workability: Plasticity index greatly reduced, viscosity eliminated, making the material easy to spread and compact.

Four Core Advantages That Address Your Key Concerns
● High Efficiency & Time Saving
Single-set waste sludge solidification equipment processing capacity reaches 40–100 tons per hour, enabling rapid on-site muck treatment without delaying construction schedules, far exceeding traditional air-drying efficiency.
● Cost Reduction
The waste sludge solidification equipment realizes on-site resource utilization, which saves huge expenses on muck transportation and disposal, while reducing the cost of purchasing earth materials, delivering remarkable overall economic benefits.
● Eco-friendly & Compliance
The waste sludge solidification equipment adopts a fully enclosed, dust-suppressed design, which ensures zero secondary pollution. The final product is inert and stable, fully complying with green construction and “Zero-Waste City” policies.
● Wide Application
The improved soil processed by the waste sludge solidification equipment can be directly used in 7 major scenarios: road subgrade filling, site leveling & foundation backfilling, embankment & slope filling, hazardous soil remediation & harmless treatment, etc.
