Bubble generation and optimization: In current research on air flotation, the generation and optimization of bubbles is an important direction. By improving the air flotation device and dissolved air system, the generation efficiency and stability of bubbles can be improved, thereby improving the treatment effect of the air flotation method. For example, the use of jet dissolved air co-current flotation process can effectively improve the utilization efficiency and treatment efficiency of bubbles.
Development and use of new flocculants: In the air flotation method, the use of flocculants is crucial to improve the treatment effect. Therefore, research and development of new and efficient flocculants is an important direction for improving air flotation. These new flocculants should have better flocculation effect, lower dosage and better environmental friendliness.
Reduction in energy consumption and operating costs: The energy consumption and operating costs of the air flotation method are relatively high, which limits its application in some fields. Therefore, studying how to reduce the energy consumption and operating costs of air flotation and improve its economic benefits is another important direction for improving air flotation. This can be achieved by optimizing equipment design, improving equipment efficiency, and reducing operating costs.
Treatment of specific contaminants: Flotation may not be effective at treating certain contaminants. Therefore, studying how to improve the flotation method to better deal with these specific pollutants is the key to improving its application scope and effectiveness. For example, wastewater containing heavy metal ions or organic pollutants may need to be treated by developing a specific flotation process or combining it with other treatment methods.
Combination with other treatment methods: The air flotation method can be used in combination with other wastewater treatment methods (such as biological treatment, chemical treatment, etc.) to improve the overall treatment effect. Studying how to effectively combine these methods to achieve efficient, low-consumption, and environmentally friendly treatment of wastewater is another direction for the improvement of air flotation.
