Shallow air flotation machine

Description

‌ Shallow air flotation machine ‌ is a water purification equipment designed based on the “shallow pool theory” and “zero speed” principles. It achieves rapid solid-liquid separation by adhering fine bubbles generated by the dissolved air system to suspended matter. Its core components include a dissolved air tank and an air compressor. The air is integrated into the water body through the pressure dissolved air system, and fine bubbles are generated after the pressure is reduced and released. The bubbles combine with the suspended flocs to form a floating body with a specific gravity less than that of water, which quickly floats to the water surface under the action of buoyancy and is centrally removed by the scraping device.
Working principle
The working principle of the shallow air flotation machine is to integrate air into the water body through the dissolved air system, and produce fine bubbles after the pressure is reduced and released. These bubbles combine with suspended matter to form a floating body with a specific gravity less than that of water, which is floated on the water surface by the buoyancy principle, thereby achieving solid-liquid separation.
Structural composition
The shallow air flotation machine is mainly composed of the following parts:
‌Dissolved air release system‌: including dissolved air tanks and air compressors.
‌Solid-liquid separation system‌: including skimming devices and sediment collection devices.
Power control system: including reducer and water distribution device. Some models are also equipped with industrial bridge and walking device to improve skimming efficiency.
Application field
Shallow flotation machine is widely used in the following fields:
Food processing: treating highly polluted wastewater containing oil and algae, with an average daily processing capacity of up to 1,000 cubic meters.
Papermaking and dyeing: suitable for models that treat sewage with a volume of up to 800 cubic meters per hour.
Municipal field: modularly designed equipment is adapted to the transformation needs of urban sewage plants.
Industrial wastewater treatment: significant effect in wastewater treatment in the petroleum, chemical, food and other industries.
Performance characteristics
Shallow flotation machine has the following performance characteristics:
High-efficiency treatment: the residence time of wastewater reaction zone is only 3-5 minutes, and the removal rate of suspended solids (SS) exceeds 90%.
Energy-saving design: power consumption is reduced by 30% compared with traditional equipment, and the floor space is reduced by 40%.
Flexible adaptation: supports customization of equipment parameters such as water purification volume and inlet turbidity.
