Dissolved Air Flotation (DAF) Optimization

2018-4-4  What is Dissolved Air Floatation? A process using air bubbles to assist with the removal of suspended matter. Compressed air is introduced to the waste stream and mixed with suspended particles causing them to become buoyant. Flow is slowed in a settling/floatation tank allowing buoyant particles to float to the top of the tank where they
