MULTIPLE CHOICE Question 17 There are multiple steps to treat wastewater from sewage. Which of the following state- ments best describes the process of aerobic secondary treatment? It encourages the growth of bacteria that remove organic pollutants, or carbon-based compounds, from sewage. A It removes large objects from sewage. It allows large solid wastes to settle out from sewage, leaving dissolved nutrients in the effluent. It filters sewage through trickle tanks containing reed beds, which help reduce the nutri- ent pollution in the effluent. B D.
