Filtration should be stopped in a filter press, if the_________________?
Correct answer: A. Both B. & C.
- A. Both B. & C.
- B. Liquor stops flowing out to the discharge
- C. Filtration pressure rises suddenly
- D. Cake becomes very dense
Explanation
A filter press should be stopped when filtrate discharge ceases or the pressure rises abnormally, since these indicate that the cake or filter medium is no longer allowing safe flow. A dense cake alone is not necessarily a stopping condition because dense cakes can still filter normally.
