If an oily-water separator uses an inclined plate pack to facilitate separation, what statement concerning the plate pack is true?
AI Explanation
The correct answer is A.
In an oily-water separator with an inclined plate pack, the oil droplets collect on the underside of the plates and rise when they have reached the outer edge of the plate pack. Solid particles collect on the upper side of the plates and sink when they have reached the inner edge of the plate pack. This is due to the difference in densities between the oil droplets and the solid particles, which causes them to separate differently as they flow through the inclined plate pack.
The other answer choices are incorrect because they describe the opposite flow patterns for the oil droplets and solid particles within the plate pack.
