Maximise bentonite recovery & water recycling in tunnelling and underground works
Our closed loop slurry treatment plants (STP’s) for use in underground works will:
• Maximise bentonite recovery
• Maximise de-sanding and de-silting of bentonite slurries
• Maximise recovery of mineral material for reuse
• Maximise water recovery for use in tunnel boring machine operations (TBM)
Bentonite recovery – our extensive experience in the design of customised hydrocyclone plants delivers unrivalled 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 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
