Dosage: Adjust the dosage of flocculant according to the properties and concentration of suspended solids in the wastewater to form suitable flocs that can effectively bind with bubbles and float up.

Dissolved gas pressure and reflux ratio: Dissolved gas pressure affects the solubility of air in water, while reflux ratio is related to the number and density of bubbles in dissolved gas water. These two need to be adjusted according to the characteristics and treatment effect of the wastewater to optimize the air flotation effect.

Hydraulic retention time: Adjust the hydraulic retention time in the air flotation tank according to the type and concentration of pollutants in the wastewater, ensuring that pollutants have sufficient time to come into contact with bubbles and float up for separation.

Surface load of air flotation tank: Adjust the surface load according to the wastewater treatment capacity and the size of the air flotation tank to ensure sufficient contact area and time for pollutant removal.

Water temperature: Water temperature has an impact on the air flotation effect, and its influence on the stability of dissolved gases and flocs needs to be considered. When the water temperature is too low in winter, it may be necessary to increase the reflux water volume or dissolved air pressure to ensure the treatment effect.

PH value: The pH value of certain industrial wastewater may need to be adjusted to optimize the effectiveness of coagulants and the stability of bubbles.

Structure of air flotation tank: Select different types of air flotation tanks based on the characteristics of wastewater, such as laminar flow, inclined plate or shallow air flotation tanks, and determine their size and shape.

The type and arrangement of the release device: The design and arrangement of the release device affect the release efficiency and distribution of bubbles, and need to be selected and adjusted according to specific situations.

Scraping frequency and method: Determine the scraping frequency and usage method based on the amount and properties of the floating slag to ensure the effective operation of the air flotation tank.
