The correct answer is A) The water may be removed through the water drain valve or through the sludge ports during the sludge discharge cycle. This is the correct answer because separator systems are designed to remove water and sludge from the processed liquid. The water that accumulates in the separator bowl can be drained through the water drain valve, and any remaining sludge can be discharged through the sludge ports during the sludge discharge cycle. The other answer choices are incorrect because B) the separator is used to remove solids, not to accumulate water, C) the water is not drained through orifice ports when the unit is secured, and D) the water can be removed without removing the bowl hood.
