What component of a reverse-osmosis freshwater generator could be isolated and replaced with the unit remaining in service?
AI Explanation
The correct answer is B) A parallel-connected membrane module.
In a reverse-osmosis freshwater generator, the membrane modules are typically arranged in a parallel configuration. This allows for individual modules to be isolated and replaced without having to take the entire unit out of service. The parallel design ensures that the remaining modules can continue to operate and produce freshwater, while the faulty or worn-out module is serviced or replaced.
The other options are incorrect because: A) The primary pre-treatment filter is a critical component that cannot be isolated without affecting the overall system performance; C) The secondary pre-treatment filter is also a critical component that should not be isolated; and D) Membrane modules in a series configuration cannot be replaced individually without disrupting the entire system.
