With increase in drum speed, in a rotary drum filter, the filtration rate_______________?
Correct answer: A. Increases
- A. Increases
- B. Increases linearly
- C. Decreases
- D. Is not affected
Explanation
Increasing drum speed gives more filtering cycles per unit time, so the filter capacity or filtration rate generally increases, within the practical operating range. At excessively high speed, cake formation time may limit this improvement.
