How It Works
Recycling NDD and drilling mud involves separating contaminants from the mud, cleaning and reconditioning these waste streams, and recovering reusable components to reduce disposal and material procurement costs.
1-Slurry & Mud Collection
NDD and drill mud wastes are collected from hydro-excavation or drilling operations, often comprising water, soil, polymers, additives and cuttings.
2-Mechanical Separation
Mechanical systems such as shale shakers, desanders, desilters and centrifuges remove coarse solids, sand and silt, allowing for initial decontamination and recovery of usable fluid.
3-Chemical Conditioning
Chemical additives adjust pH, destabilise emulsions and enhance the separation of oil and contaminants, improving the efficiency of solid–liquid separation.
4-Biological & Fine Contaminant Treatment
Microbial processes can further degrade organic contaminants, while fine solids and residuals are separated and stabilised.
5-Resource Recovery & Disposal
Recovered drilling fluid, water and solids can be reused or safely disposed of in accordance with regulatory guidelines, reducing overall waste and environmental impact.

Core System Components
AquipTec configures NDD Mud and Drill Mud Recycling systems by combining mechanical, chemical and biological technologies designed to remove contaminants and recover usable materials.
Mechanical Separation Systems
Mechanical separation is the first stage, removing solids and coarse contaminants:
• Shale shakers & vibrating screens filter large cuttings and debris.
• Desanders & desilters remove sand and fine particles.
• Centrifuges accelerate gravity separation and extract solids from liquid.
These systems maintain mud properties and protect downstream equipment.
Chemical Conditioning Modules
Chemical systems enhance separation and fluid stability:
• Chemical dosing skids for pH and emulsion control.
• Flocculant and coagulant dosing to promote agglomeration of fine particles.
• Mixing and reaction tanks for effective conditioning.
Chemical conditioning boosts overall separation performance.
Biological Treatment Systems
Biological processes support further contaminant breakdown:
• Bioreactors and microbial dosing systems used where organics require decomposition.
• Nutrient delivery and monitoring systems to support microbial activity.
• Aerobic/anaerobic zones adapted to waste characteristics.
Biological treatment enhances removal of organic contaminants when required.

Frequently Asked Questions (FAQ)
What is NDD Mud?
NDD Mud is the slurry generated during non-destructive digging (hydro excavation), made from water, soil and drilling fluids.
Why recycle drill mud?
Recycling removes contaminants, recovers usable fluid, reduces waste and cuts procurement and disposal costs.
Can recycled mud be reused?
Yes, treated mud and fluids can often be reused in further drilling operations with restored performance.
Is biological treatment necessary?
Biological treatment enhances contaminant breakdown but is complementary; mechanical and chemical separation are core.
Can these systems be retrofitted?
Yes, modular components can integrate with existing waste management or drilling support infrastructure.
