The composition of an air flotation machine generally includes the following parts:

(1) Efficient dissolved air flotation system

The air flotation system integrates water intake, flocculation, separation, water collection, and effluent. Similar to traditional air flotation equipment, it is equipped with a stable flow chamber and a dissolved air release chamber, which makes the treatment performance more stable and the effect more efficient. It is particularly suitable for the transformation of traditional equipment.

Stable chamber: The raw water reacted through folded plates has a high flow rate. If it comes into direct contact with dissolved air water, it will dissipate small bubbles, affecting the adhesion of bubbles to flocs and reducing the efficiency of air flotation treatment. If a stable flow chamber is added, the kinetic energy of turbulent raw water will be consumed and enter the dissolved air water release chamber at a uniform speed, effectively ensuring the removal effect.

Dissolved gas release chamber: The dissolved gas release chamber and the separation chamber are located in the same tank. Separated in the middle, the dissolved air water and the flocculated raw water adhere here, slowly rise, and enter the air flotation separation chamber, ensuring the contact space and time between the floc and the small bubbles, resulting in a higher release rate of dissolved air water

(2) Dissolved gas system

For efficient shallow air flotation equipment, the dissolved air system is the main component. At this stage, gas and water are sucked in together at the inlet of the pump, and are mixed into dissolved air and water in the dissolved air tank through impeller shear and pressure. The gas-liquid phase is fully mixed and reaches saturation. The entire dissolved air system has a large gas content of about 10%, which makes the distribution of microbubbles during gas dispersion uniform, with an average bubble diameter of less than 30um. This dissolved air system is an improvement and technological innovation of traditional air flotation, which improves the separation efficiency of air flotation and greatly reduces the production and operation costs of the equipment.

(3) Scraper machine

The operation mode and speed of the scraper directly affect the water quality of the air flotation effluent and the solid content of the sludge. The system adopts a rotary scraper, which can continuously and uniformly scrape the floating slag into the floating slag tank, reducing the phenomenon of collision between floating slag; In addition, the height adjustable scraper can better adapt to various operating conditions and reduce the moisture content of sludge.

(4) Control system

The control system uses electrical components to ensure the effective operation of the equipment.
