Wastewater Clarification Systems | Beckart Environmental

Flotation Tanks Compared to sedimentation tanks, dissolved air flotation (DAF) and induced air flotation (IAF) tanks essentially take the opposite approach Tiny bubbles are introduced into the wastewater before it reaches the clarifier, and these bubbles attach themselves to solid particles, raising the waste to the surface of the tankDissolved Air Flotation - Aquatec Maxcon,Dissolved Air Flotation Dissolved Air Flotation (DAF) is another form of clarification process that relies on flotation of floc particles to the surface instead of gravity sedimentation It is suited to particular quality raw water streams – generally low turbidity, coloured waters which would otherwise be more difficult to treat by sedimentationFlotation Technology | SUEZ Water Technologies & Solutions,Dissolved Air Flotation (DAF) technology is an effective clarification method for low-density solids that sedimentation cannot remove in applications such as drinking water, process water, and
