Mathematical model of Dissolved Air Flotation System

Dissolved air system is an important part of the air flotation device. In order to ensure the stability of air content in dissolved water, it is essential to establish a scientific mathematical model to reach the equilibrium operating point of the device by the automatic control of the pressure p and flow Q. According to the working principle of dissolved gas cylinders, this article simplifies the setting of the conditions with small interfering factors, seizes the main influencing factors and investigates the relationships among the variables of the dissolved air systems, and uses differential equations to establish a preliminary mathematical model and describe the mathematical relationship between air pressure and liquid level in the dissolved gas cylinders, so as to provide a basis for automatic control equipment to keep equipment running stable in accordance with the tank pressure.
