Does shallow air flotation machine need slag scraper?

The shallow air flotation machine is a kind of equipment widely used in the field of water treatment. Its main function is to generate microbubbles to cause suspended solids or grease and other pollutants in the water to adhere to the bubbles, and then float to the water surface, achieving Solid-liquid or liquid-liquid separation. This equipment has demonstrated efficient and stable performance on many occasions.
The main function of the slag scraper is to remove debris or pollutants floating on the water surface, keep the water surface clean, and prevent these debris from being mixed into the water again. In some application scenarios, the slag scraper is the key to ensuring continuous and stable separation effect.
For the shallow air flotation machine, since its working principle is based on the adhesion of microbubbles and pollutants to achieve separation, when processing some wastewater containing high concentrations of suspended solids or grease, a thick layer may be formed on the water surface. of scum. If these scum are not cleaned up in time, they may be remixed into the water and affect the separation effect.
Therefore, the shallow air flotation machine needs to be equipped with a slag scraper in certain application scenarios. The use of a slag scraper can ensure the stable processing effect of the shallow air flotation machine and extend the service life of the equipment. However, in some application scenarios where the treated water quality is good and the concentration of suspended solids is low, the use of a slag scraper may not be necessary.
