How does a rotary drum filter work?
How does it work?
- As the drum rotates, it is partially submerged in the feed slurry.
- Vacuum draws liquid through the filter medium (cloth) on the drum surface which retains the solids.
- The vacuum pulls air (or gas) through the cake and continues to remove moisture as the drum rotates.

What is the rate of filtration for pressure filter?
The range of rate of filtration of pressure filters is 6000 to 15000 liters per hour per sq. m of filter area.
In which type of filter rate of filtration is more?
Note:
| Characteristics | Slow Sand Filters | Rapid Sand Filters |
|---|---|---|
| Rate of filtration | Low, typically ranges 100 to 200 liters per hour per sq. m of filter area. | High, typically ranges 3000 to 6000 liters per hour per sq. m of filter area. |
Is the example of pressure filters?
Pressure filters are routinely used in daily life, such as in a vacuum cleaner with a dust bag or paper filter or an automobile engine with an oil filter cartridge. Many industrial operations involve the filtration of slurries that contain high concentrations of suspended solids.
