Challenges in Tunneling Slurry Treatment
During tunnel construction, slurry treatment is a critical factor affecting project progress and costs. Traditional treatment methods face numerous challenges:
High Moisture Content Issues
Tunnel slurry typically has moisture content of 75-85%, resulting in large volume, high transportation costs, and failure to meet environmental discharge standards.
Environmental Compliance Pressure
Strict environmental regulations require slurry treatment to meet discharge standards, with traditional methods struggling to achieve SS content below 0.3%.
Low Construction Efficiency
Traditional slurry treatment methods are inefficient, occupy large construction areas, affect project progress, and increase labor costs.
High Transportation Costs
High moisture content slurry has large volume, resulting in high transportation costs and environmental pollution risks during transport.
How Decanter Centrifuges Solve Tunneling Slurry Dewatering Challenges
High-Efficiency Separation Principle
ZK decanter centrifuges utilize advanced centrifugal separation technology, generating powerful centrifugal force through high-speed rotation to rapidly separate solid particles from liquid in tunnel slurry.
