Centrifugation - Wikipedia
Centrifugation - Wikipedia

Centrifugation, is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. The more dense components of the mixture migrate away from the axis of the ,centrifuge,, while the less dense components of the mixture migrate towards the axis. Chemists and biologists may increase the effective gravitational force of the ,test, …

Centrifuge spin, is another common method. And really, the ,spin, is actually very versatile. By measuring samples of the mixed liquor, the return sludge, and the clarifier at once you can get an idea of the mass/balance. And also decide whether you need to waste or whether you need to change your return activated sludge (RAS) rate.
