They will also be aware of the complexities of this system, which may seem to operate behind the scenes in a seemingly flawless fashion. The Wastewater Unit will introduce key terms such as wastewater, influent, water pollution, bio solids, sludge, aeration, and effluent. Students will be presented three lessons, each a very different format. The first lesson is a general overview with a slide show of the wastewater treatment process. The second lesson focuses on modeling the wastewater treatment process.
Students use a controlled experiment to compare untreated and treated water.
In the third lesson students use Stella to manipulate the water treatment process and determine the effects on the environment into which the effluent is released. The process of water treatment will be the focus. Briefly, the history of wastewater treatment in NYC will be covered, along with engineering and urban planning issues associated with wastewater removal in a large city. Information will be presented in a slide show followed by a discussion of pertinent wastewater issues. Wastewater Treatment Exercise Students conduct a controlled experiment using three jars, each with different components to simulate the wastewater treatment process.
