Gelatinous solid (which plug the septum) can be filtered by a _____________ filter?
Correct answer: B. Pre-coat
- A. Sparkler
- B. Pre-coat
- C. Vacuum leaf
- D. Plate and frame
Explanation
A pre-coat of filter aid forms a porous filtering layer that prevents gelatinous solids from sealing the filter medium or plugging the septum. This is why pre-coat filters are preferred for such difficult slurries.
