Question

You have been hired by a small wastewater engineering consultancy. One of your first projects involves the design of an industrial wastewater treatment plant. After doing a lot of background research and preliminary design calculations, an intern assigned to the project tells you that there are only two possible processes that can be included in the design for the removal of pollutant “A”. Further, the intern tells you that one of the alternative processes is a physical unit operation while the other is a chemical unit process. If both alternatives can deliver the same removal efficiency, which one will you pick? Please give reasons for your answer.
