High-rate clarifier exclusively developed and patented by Veolia Water Technologies.
ACTIFLO® is a high-rate and compact water clarification process in which raw water is flocculated with microsand and polymer in a Turbomix® draft tube reactor.
The microsand enhances the formation of robust flocs and acts as ballast, significantly increasing their settling velocities. The unique characteristics of the resulting microsand ballasted flocs allow for clarifier designs with very short hydraulic residence times, high rise rates and extremely compact system footprints that are up to 50 times smaller than other clarification processes of similar capacity.
• High rate separation
• Small footprint & low construction cost
• Flexible treatability covering wide fluctuations of turbidity and quantity of influent
• Quick operation start in less than 20 min
• Good treated water quality
• Low operation cost
