Dissolved Air Flotation. Fluence’s dissolved air flotation (DAF) systems provide high-quality, efficient clarification of suspended particles from wastewater. Dissolved air flotation (DAF) uses microfine bubbles to float greases, oils and solids to the surface, from where they're removed. Fluence has been developing and continually improving dissolved air flotation (DAF) systems for decades
Get PriceDissolved air flotation is best applied to remove materials that normally settle slowly, persist by remaining in suspension, or have a tendency to float. Benefits of flotation are rapid process results – flotation happens immediately while sedimentation takes time, higher loading rates than gravity thickening, and fresher sludge / solids
