Tunneling & Underground Works

Maximize bentonite recovery & water recycling in tunneling and underground works

Our closed loop slurry treatment plants (STP’s) for use in underground works will:

  • Maximize bentonite recovery
  • Maximize de-sanding and de-silting of bentonite slurries
  • Maximize recovery of mineral material for reuse
  • Maximize water recovery for use in tunnel boring machine operations (TBM)

Bentonite recovery – our extensive experience in the design of customized hydrocyclone plants delivers unrivaled cut point accuracy

De-sanding & de-silting of bentonite slurries – our high-frequency dewatering technology ensures the efficient separation of your crushed material from bentonite slurries

Recovery of mineral material for reuse – following dewatering your mineral tunnel waste can be screened and graded to allow for the on-site production of mass concrete and sprayed concrete

Water recycling & sludge management – introduction of our thickening and sludge management systems to deal with the recovered bentonite slurries allows process water to be recycled to your TBM operations
