May I ask, in an air flotation tank used for scum removal, how high is the scum layer or oil layer above the surface of the clear water? How deep does the scraper go into the liquid surface? Are there any standards?

It seems there are no specific requirements; it’s sufficient as long as the slag can be removed.
So how tall are you guys usually? ? ?
Looking at the slag level, it is generally 4-5 cm
Is it possible to take a partial screenshot? I’d like to see the depth of the scraper below the level of the clean liquid, as well as the height of the slag layer, and a picture showing how the scraper removes the slag. Thank you!
There seems to be no standard for this: generally, it is determined based on factors such as the amount of scum, the density of the medium, and its viscosity.
Generally, the scraper starts to operate when it has rotated to 2/3 of its full cycle, scraping away the scum or oil layer at a distance of about 50 mm above the surface of the clear water.
