Expertise

FLI QDS have delivered more than 500 successful remediation projects in the UK and abroad using the full range of remediation technologies. Remediation techniques we have employed at full and pilot scale include the following. In many cases multiple technologies have been combined to optimise the remediation of complex sites.

Ex-situ

  • Bioremediaton
  • Stabilisation / solidification
  • Soil processing and materials management
  • Thermal desorption
  • Asbestos in soils
  • Chemical oxidation
  • Excavation and disposal
  • Japanese Knotweed
  • Phytoremediation
  • Spill response

In-situ

  • Air sparge
  • vacuum extraction
  • Dual phase vacuum extraction (multiphase recovery)
  • Chemical oxidation (multiple methods)
  • Free phase recovery (LNAPL &  DNAPL)
  • Flow path management
  • Groundwater re circulation
  • Pump and treat
  • Plume delineation and management
  • Thermal (steam stripping)
  • Thermal (conductive heating)
  • Aerobic bioremediation
  • Anaerobic bioremediation (Enhanced Reductive Dechlorination)
  • In-situ chemical reduction
  • Monitored Natural Attenuation
  • Surfactant flushing
  • In-situ stabilisation
  • Cut-off walls and permeable reactive barriers

Water treatment

  • Automated pumping systems with telemetry
  • Silt / solids separation
  • Activated carbon filtration
  • Precipitation / coagulation / flocculation
  • pH amendment
  • Dosing systems
  • Ion exchange
  • Air stripping
  • Methane stripping
  • Ammonia treatment
  • Bioreactors
  • UV filtration
  • Construction site contaminated water management
  • Pilot scale systems
  • Hydrogeological testing
