To optimize the treatment effect of the air flotation machine, we can start from the following aspects:

1. Bubble size and distribution

Optimize the gas dissolution system: ｓｅｌｅｃｔ appropriate gas dissolution pumps and cylinders to ensure the generation of small and uniform bubbles. The ideal bubble diameter is generally controlled between 20-60 microns.

Adjusting pressure: Appropriately increasing the pressure of dissolved water can generate smaller bubbles and increase the chance of contact between bubbles and suspended solids.

2. Selection and use of coagulants

Choose the appropriate coagulant: ｓｅｌｅｃｔ the most suitable coagulant based on the specific properties of the wastewater, such as pH value, temperature, suspended solids type, etc.

Optimize the dosage of coagulant: Determine the optimal dosage of coagulant through experiments to avoid excessive or insufficient dosage.

Mixing method: Efficient mixing equipment is used to ensure that the coagulant is fully mixed with the wastewater, thereby improving the coagulation effect.

3. Control the water flow rate

Reasonable design flow rate: Ensure that the water flow rate is moderate, neither too fast to allow bubbles and suspended solids to combine in time, nor too slow to reduce treatment efficiency.

Uniform water distribution: Ensure that the incoming water is evenly distributed throughout the entire air flotation tank, avoiding local water flow that is too fast or too slow.

4. Adjust the pH value

Adjust pH value: Adjust the appropriate pH value based on the properties of suspended solids in the wastewater to facilitate the effectiveness of coagulants. Normally, pH values between 6.5-8.5 are more effective.

5. Temperature control

Maintaining an appropriate temperature: Appropriate water temperature can enhance the activity of coagulants and improve the coagulation effect. The generally recommended temperature range is 20-30 ℃.

6. Air flotation time

Extend the air flotation time: Properly extend the air flotation time to ensure that the bubbles and suspended solids have enough time to combine and float up.

Reasonably design the depth of the air flotation tank: The depth of the air flotation tank should not be too deep to avoid affecting the rising speed of bubbles.

7. Optimization of Scraping System

Regular cleaning of floating debris: Clean the floating debris on the surface of the air flotation tank in a timely manner to prevent the accumulation of floating debris from affecting the treatment effect.

Optimize slag scraping equipment: Choose efficient slag scraping equipment to ensure smooth discharge of floating slag.

8. Regular maintenance and inspection

Regular equipment inspection: Regularly inspect and maintain the air flotation machine to ensure the normal operation of all components.

Monitoring water quality parameters: Regularly monitor the water quality parameters of incoming and outgoing water, adjust operating parameters in a timely manner, and ensure treatment effectiveness.

Through the above measures, the treatment efficiency of the air flotation machine can be significantly improved, ensuring that the effluent quality meets the expected standards.
