The ratio for the rate of washing to the final rate of filtration in a washing type of plate and frame filter is____________________?
Correct answer: A. 0.25
- A. 0.25
- B. 0.50
- C. 0.75
- D. 1.25
Explanation
In a plate-and-frame filter, washing is commonly carried out at about one-fourth of the final filtration rate because the wash liquid must pass more slowly through the deposited cake for effective displacement.
