Algae Removal Using Dissolved Air Flotation (DAF)

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.

They contact and adhere together to take shape of air-containing flocs that float to the surface and are mechanically scrap by scum skimmer. Then water will be purified. The theoretical basis of the air-dissolving process is Henry's Law means that in air-floatation system air dissolves in water under high pressure and approaches saturation ...

Dissolved Air Flotation (DAF) is a widely used clarification ...

Dissolved Air Floatation (DAF) is a widely used clarification process especially in India. DAF removes particles from water using air bubbles that collide and attach to particles. The particle bubble aggregates are then separated once they rise to the surface of the tank. It has applications in several fields which include drinking water ...

Dissolved Air Flotation Systems - Sustainable Water Use ...

Dissolved Air Flotation (DAF) has been known as one of the most effective and robust ways to remove suspended solids (TSS) biochemical oxygen demand (BOD5) fats oils and grease (FOG) phosphorus (P) or nutrients from industrial wastewaters. In response to variations in industrial activity variations in wastewater and water streams and the ever-demanding customer requirements Nijhuis Industries has engineered one of the most intelligent and reliable Dissolved Air Flotation systems (i-DAF

Dissolved Air Flotation - an overview | ScienceDirect Topics

Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotation (DAF) process mixes a clarified stream from the outlet of the unit with air at 3–9 bar to produce a supersaturated (compared with saturation at atmospheric pressure) solution of air in water.
