Many clients have contacted us seeking assistance with issues they've encountered while using dissolved air flotation (DAF) machines. They hope for our guidance. Today, I will delve into the thermodynamic principles of DAF machines, hoping to provide insights and assistance to our clients. This should offer a deeper understanding of the DAF machines and enable users to operate them confidently and effectively in the future.

The dissolved air flotation (DAF) machine is widely used in various industries such as waterworks, wastewater treatment plants, steel, oil, chemical, dyeing and printing, and textile, where air and recycle water are吸入 simultaneously through the pump inlet. They are then chopped into fine dissolved air water by the pump impeller, followed by a pressure-reducing valve to release it as milky white dissolved air water, causing flocs to float up to achieve purification. Now let's analyze the thermodynamic principle of the dissolved air flotation machine.

The micro-bubbles on the surface of the dissolved air flotation machine have some transparent water films. Besides the loose outer layer encountering resistance and affecting flow during ascent, there are stable micro-bubbles rising. After aggregation, there should be excess groups. The friction between them generates heat, which is the thermodynamic principle of the dissolved air flotation machine.
