5. How a rotary drum vacuum filter works ...

6. As the panel is immersed,
the liquid is drawn through
the panel and the solids are
retained on the panel
surface.
As the panel continues to
rotate, air is drawn through
the panel to dewater the
solids.
The filtered solids are
removed from the
panel surface.
Vacuum is applied to the
panel through the rotary
valve assembly.
