A typical disk centrifuge stack contains 100 or more disks. The disks reduce the distance that a solid particle must travel before it is separated from the feed. Disk centrifuges range in diameter from 102-762 mm, and are capable of creating forces up to 14,000 times that of gravity. The two diagrams below show how disk centrifuges work.

Figure 8.1.1: Filter paper disk method experiment showing zones of inhibition. The use of antimicrobial agents to treat infections began in the early 1900's, when Paul Ehrlich developed Salvarsan to treat individuals infected with Treponema pallidum, the spirochete that causes syphilis. In 1928, Alexander Fleming later observed that the ...
Disc Filter
The rotary disc filter cycle as shown in Figure 7.5 is restricted to single cake formation and deliquoring phases (see also Section 1.4.1.6).Due to the vertical orientation of the sectored discs, displacement washing, although technically feasible, is difficult to perform reliably. A typical cycle is initiated by causing the discs to rotate through the trough of suspension …

When To Use a Disc Filter vs a Screen Filter • Vu-Flow
As far as flow rate capacity is concerned, disc filters are generally better used with high flow rates, and screen filters are better suited for low to medium flow rates. Another point to consider deals with cleaning the filters. The cleaning process for a screen filter is usually as simple as rinsing it off or taking a soft brush to it.
