Advantages of Shallow air floatation

2025-04-27
Shallow air floatation has significant advantages in water treatment and other fields, which are mainly reflected in the following aspects:
1. Efficient separation
The unique shallow structure design greatly shortens the floating distance and time of flocs, so that the flotation process can be completed in a shorter hydraulic retention time, usually only 3-5 minutes, which is significantly improved compared to traditional flotation. This high efficiency helps to quickly achieve solid-liquid separation, and the removal rate of pollutants such as algae, emulsified oil, and fine suspended particles can reach more than 90%, and the effluent water quality is excellent.
2. Energy saving and consumption reduction
When the system is running, the air-water ratio is low. There is no need to dissolve a large amount of air in water through high pressure like dissolved air flotation, which effectively reduces the energy consumption of air compressors and water pumps, and the operating cost can be reduced by 30% - 50%. At the same time, the shallow air floatation equipment occupies a small area, reduces infrastructure investment, and the cost of equipment procurement and installation is also reduced accordingly.
3. Stable performance
It has strong adaptability to water quality changes and can effectively cope with fluctuations in inlet water temperature, pH value, suspended solids concentration, etc. Even under unstable water quality conditions, it can still maintain a stable treatment effect, and the effluent water quality compliance rate is high, which ensures the stable operation of subsequent processes and is suitable for a variety of complex water quality treatment scenarios such as domestic sewage and industrial wastewater.
4. Easy operation and maintenance
The equipment has a compact structure and a simple layout, and each component is easy to inspect and maintain. The operation control system is simple and intuitive. The staff can master the operation process after short-term training. Inspection, cleaning, troubleshooting and other tasks in daily operation are convenient, which effectively reduces labor costs and operation and maintenance difficulties.
5. Green and environmentally friendly

With its excellent pollutant removal ability, it reduces the discharge of pollutants from sewage into natural water bodies and protects the ecological environment. The low-energy operation mode also reduces carbon emissions, conforms to the concept of sustainable development, helps enterprises achieve green production goals, and complies with current environmental protection policy requirements and development trends.
