ACTIFLO® is a proven Veolia Water Technologies offering with more than 500 installations worldwide. This compact process operates with microsand as a seed for floc formation. The sand provides surface area that enhances flocculation and also acts as a ballast or weight to aid rapid settling. These designs result in footprints that are five times smaller than classic lamella clarifiers and dissolved air flotation (DAF) units and up to 20 times smaller than conventional clarification systems. A very high rate settling process results in a small footprint.

ACTIFLO® TURBO is the next generation of the proven ACTIFLO® technology. It includes our latest innovation – a Turbomix™ reactor - developed through computational fluid dynamics (CFD) modeling. The complete mixing of the new reactor design reduces the footprint of the ACTIFLO® by nearly one-half and enables the addition of water softening chemistry. As a result, this technology has multiple applications in the Oil & Gas industry, including:

  • Process Water Softening for Boilers and Cooling Towers
  • Clarification of Supply Water
  • Pretreatment for Desalination
  • Cooling Tower Blowdown Treatment
  • Tertiary Treatment for Reuse
  • Primary Wastewater Treatment

Benefits

  • Extremely small footprint
  • Easy start-up and shutdown (less than 15 minutes)
  • Very high rising rate in comparison to conventional clarification and softening systems
  • Fully automated system that reduces the manpower needs
  • Ability to handle strong load variations up to 2000-4000 NTU with no impact on effluent quality
  • Process is effective with TSS loading rates >2000 ppm (TSS ~ 4600 ppm, Sludge ~ 38400 ppm)
  • Ability to treat up to 150% of the design influent flow without degradation in performance
