A Veolia-patented high-performance water clarifier for municipal and industrial water treatment.
Designed to further enhance water quality, ACTIFLO® Softening combines in a single compact treatment unit both clarification and softening operations to reduce water alkalinity and hardness. At the same time, the process removes other water components such as silica, heavy metals, fluorides and phosphates as well as TSS (Total Suspended Solids) and organic matter.
Rapid and efficient, ACTIFLO® Softening produces very high quality water.
ACTIFLO® Softening is an ideal solution for many industrial and municipal applications:
- Surface and groundwater softening for drinking water production
- Water pre-treatment to avoid potential membrane scaling
- Water production for cooling tower make-up
- Water recycling for cooling tower sidestream
- Treatment of produced water in the Oil & Gas industry
- SAGD (Steam Assisted Gravity Drainage) water treatment for reuse
- Wastewater treatment of flue gas desulfurization and acid mine drainage
- Wastewater reuse in the steel and metal industry
- Phosphorus co-precipitation
- Very small footprint: ACTIFLO® Softening is up to 10 times smaller than conventional softening processes
- High rise rate: Up to 120 m/h
- Retrofit: Can be easily implemented in existing tanks
- Enhanced chemical precipitation with Turbomix™ draft tube
- Minimizes coagulant consumption due to solids precipitation with calcium carbonates
- Sludge up to 8% dry solids; can be easily thickened and dewatered
- Easy start-up: Within few minutes
- Plant-wide automation: ACTIFLO® Softening can be fully automated and integrated into existing plants

Resources & Product range
A polishing solution designed to achieve high removal levels of suspended solids and phosphorus in municipal and industrial wastewater for water reuse. It combines two treatment processes: a conventional Actiflo phase followed by a rotating disc filter polishing system for tertiary treatment.
A two-in-one, ready-to-use system designed to adjust to substantial fluctuations in wastewater flows. It can operate as a conventional lamella clarifier in times of low flow or as a coagulation/flocculation with settling ballasted and micro sand in times of high flow.
Clarification and Flotation
This technology combines the features and the efficiency of standard Actiflo with the adsorption qualities of activated carbon to remove compounds that are refractory to water clarification. Thanks to powdered activated carbon, it ensures the production of high-quality drinking.
