In Shield Tunnelling or Micro-tunnelling Project, If the mud contains high sand, clay, silt, suspensions of cement and bentonite, the mud treatment solutions should be recommend to use  Decanting Centrifuge to Cleaning Mud in Micro-tunnelling Project.

Tunneling and soil drilling mud usually contains sand, clay, silt, but also suspensions of cement and bentonite. These are generally considered quite complex sludge to be treated, because of their high abrasiveness, viscosity and density, therefore the need of high performance and wear resistance centrifugal systems becomes essential.

Brightway decanting centrifuges are designed with practical structure and environmental friendly concept. The middle speed, high speed and variable-speed decanting centrifuges can separate and remove solid phrases in drilling fluids with safe, consistent, and efficient working performance.

Thanks to a unique, strong frame design and to the use of premium raw materials and components, Brightway centrifuges can be employed across every sludge treatment process.
