What is SLUSORB™?
It is a highly hydrophilic polymer capable of absorbing and retaining hundreds of times its own weight in water or liquid. Through its network and cross-linked structure, it captures and locks in water molecules, preventing leakage. Specifically designed for HDD mud, it efficiently handles Bentonite-based mud, water-based mud, and mixtures thereof, as well as waste generated from hydraulic excavation. The usage rate is extremely low, typically 0.5%–1.5% of the mud weight, with minimal volume expansion (approximately 1%), resulting in significant cost savings.
Key Advantages
Low Dosage, High Efficiency
Only 0.5–1.5% (by weight) of SAP is needed to completely solidify liquid sludge within minutes.
Cost Savings
Reduced vacuum truck frequency and transport volume → Reduced labor, transportation, and tipping costs.
Environmentally Friendly & Safe
Complies with EPA 9095B paint dripping standards, reducing the risk of leakage/leakage; non-leachable after solidification; prevents liquid from flowing into the environment.
No Complex Equipment Required
Only standard machinery (such as an excavator) is needed for mixing; no heavy equipment such as centrifuges or filter presses is required.
Long-Term Stability
SAP is stable in landfill environments and is not easily decomposed by microorganisms, thus locking in the liquid.
Flexibility/Scalability
Different forms and chemical formulations (granular, fibrous, particulate, etc.) are available for various operating conditions (high-salt, conductive liquids, etc.).
Application Method in HDD Projects
Collect waste mud in pits or roll-off containers. If the project is in a remote area or temporary site without a centralized treatment point, on-site solidification can be performed. SLUSORB™ can also be used to solidify slurry mixed with mud and cuttings.
1. Waste Liquid Collection
After the drill bit is pulled back, transfer the waste mud from the vibrating screen or mud tank to a roll-off container or a pre-designated solidification area.
2. Polymer Addition
Before the mud is ready for transport or landfill, perform on-site solidification by directly spreading polymer powder onto the mud surface at a very low recommended dosage (typically 0.5%–1.5% of the mud weight).
3. Rapid Mixing
Use the bucket to rapidly mix the mud and polymer; the solidification reaction is usually completed within 15–30 minutes.
4. Final Disposal
After solidification, the slurry becomes a stackable solid and undergoes a Paint Filter Test (EPA 9095B). The solidified material is immediately transported to a landfill for final disposal, without the need for prolonged drying or reaction.
Long-term Stability: SAP exhibits good stability in landfills and is not easily biodegradable (it does not release previously absorbed liquid in landfill environments).
Note: Please test the slurry properties (conductivity/ionic strength/particle size/liquid content) before purchasing.
