What are the ways to produce bubbles in air flotation?

In sewage, once various impurities appear, it will directly affect the effect of the entire sewage treatment. Therefore, it is particularly important to choose the right equipment, especially modern air flotation, which is also a commonly used equipment for sewage treatment. In short, it can directly generate bubbles in the sewage, and then adhere to some particulate matter in the sewage through the bubbles, thereby It can surface, and the separation of materials and water is the key to achieving the separation of materials and water.
Since air flotation is necessary, so air bubbles are used, then these methods can be used. One is the method of direct electrification, that is, the sewage or waste water can be directly connected to the relevant direct current, so that some air bubbles can be generated to complete the bonding of the particulate matter, but due to its large power consumption, it is easy to generate dirt, so Can be widely used in some small sewage treatment.
The other method belongs to the ventilation method, which has also become a method that needs to be used in air flotation. Simply put, it can directly install a drain pipe at the bottom, and then use compressed air to push the air bubbles directly into the water. Especially because there is also an impeller inside, so the agitator can be done through the impeller, so that the air bubbles in the water can be directly divided into small bubbles.
The last method belongs to the method of dissolving bubbles, which can directly dissolve gas, generate bubbles, and complete sewage treatment. Therefore, the current air flotation mainly uses several methods to generate air bubbles and remove impurities in sewage.
