Algae at both low and high concentrations may be removed by dissolved air flotation (DAF). Even very high concentrations from wastewater treatment lagoons and algae culture ponds are efficiently removed.

Request PDF on ResearchGate | Comparing dissolved air flotation and conventional sedimentation to remove cyanobacterial cells of Microcystis aeruginosa: Part I: The key operating conditions | Dissolved air flotation (DAF) is generally considered more effective than sedimentation (S) in the treatment of algal-rich water.

Since algae are low-density particles and some may float, dissolved air flotation (DAF) has proven to be more effective for treating algal-rich water than the conventional clarification by settling. Bauer et al. demonstrated the DAF efficiency for treating algal rich waters from the Thames river in a full-scale plant.

Dissolved air flotation is an alternative clarification process ideal for treating raw water with light particles, such as algae or color-causing organics, and at low temperatures when sedimentation is not as effective.

Additionally, their low turbidity, soft and high color nature produces very light flocs which settle very slowly. This study investigated the performance of the Dissolved Air Flotation (DAF) process as an alternative to sedimentation for algae removal in surface water treatment in Kenya.

Dissolved air flotation is an alternative clarification process ideal for treating raw water with light particles, such as algae or color-causing organics, and at low temperatures when sedimentation is not as effective.

A better approach is to physically remove the algae and reduce the concentration of phosphorus in the water. A simple process of clarification via Dissolved Air Flotation (DAF) and phosphorus precipitation can stop an algae bloom in its tracks. We’ve used the DAF process many times to help with algae removal in surface bodies of water.

Dissolved air flotation (DAF) is an excellent solution for clarifying water with high levels of algae and other low-density solids that cannot be removed efficiently with sedimentation. The AquaDAF® clarifier combines conventional Dissolved Air Flotation (DAF) principles with several enhanced components, including a unique effluent collection system.
