Shallow air flotation machine is an efficient water treatment equipment, mainly used to remove suspended solids and impurities in water. Its working principle is to generate a large number of fine bubbles through a dissolved air system, which adhere to suspended particles, causing their density to decrease and float to the water surface, forming floating slag that is scraped off, thus achieving the goal of purifying water quality.

Working principle

Shallow air flotation machine achieves efficient processing through the following steps:

Dissolving process: Under high pressure conditions, air dissolves in water to form fine bubbles.

Bubble adhesion: Fine bubbles adhere to suspended particles, reducing their density.

Floating separation: Suspended solids with attached bubbles float to the surface of the water, forming floating debris.

Scraping off floating slag: The floating slag is removed from the water through a scraping device.

Characteristics and application scope

Shallow air flotation machine has the following characteristics:

Low water flow velocity: The relative velocity of water to the pool wall is close to zero, without stirring the water, resulting in a high degree of purification.

High utilization rate of dissolved air: high unit dissolved air rate and good air flotation effect.

Small footprint: Compact structure, suitable for various installation environments.

Efficient processing: Suitable for removing small suspended particles with a specific gravity close to water, with a suspended solids removal rate of over 90%.

Shallow air flotation machines are widely used in wastewater treatment systems in industries such as petroleum, chemical, steel, leather, electricity, textile, food, brewing, and municipal engineering, and are a substitute for traditional air flotation equipment.
