Cake resistance is___________________?
Correct answer: C. None of these
- A. Important in the beginning of filtration
- B. Decreased with the time of filtration
- C. None of these
- D. Independent of pressure drop
Explanation
Cake resistance is initially small because little cake has formed, then increases as solids accumulate on the filter medium. Its dependence on pressure drop also varies with cake compressibility, so none of options a to c is generally valid.
