OPTIMIZING DISSOLVED AIR FLOTATION DESIGN

In dissolved air flotation (DAF), the water saturated with air under pressure (higher than 3 atmospheres) passes through a nozzle whereby the bubbles are formed and reach the flotation chamber, which is at atmospheric pressure.

Behaviour of air injection nozzles in dissolved air flotation

A simple two phase conceptual model is postulated to explain the initial growth of microbubbles after pressure release in dissolved air flotation. During the first phase bubbles merely expand from existing nucleation centres as air precipitates from solution, without bubble coalescence.

Dissolved air flotation

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms
