Filtration operation carried out by continuous increase of the inlet pressure of slurry, is called the _____________ filtration?
Correct answer: D. Constant rate
- A. Constant pressure
- B. Varying pressure
- C. Varying rate
- D. Constant rate
Explanation
When slurry is filtered at a constant rate, the cake resistance increases and the inlet pressure must continuously rise. Thus, increasing inlet pressure describes constant-rate filtration.
