ACTIFLO® Ballasted Clarification Process BrochureSource: Veolia Water Solutions & Technologies
The ACTIFLO® technology is a compact process that operates with microsand as a seed for floc formation. The microsand provides surface area that enhances flocculation and acts as a ballast to form robust and rapidly settling floc.
The unique settling characteristics displayed by the microsand ballasted floc allow for clarifier designs with high overflow rates, short retention times and minimal sludge presence within the unit. These designs result in footprints that are five times smaller than classic lamella clarifiers or dissolved air flotation (DAF) units and up to 20 times smaller than conventional clarification designs.
