The speaker, John Foster, is a professor whose focus is Nuclear Engineering and Radiological Sciences at the University of Michigan. He received his bachelor degree in Physics in 1991 from Jackson State university. With hard work in advanced studying, he got his PhD in Applied Physics in 1996 from University of Michigan.
In this presentation, the speaker is talking about using Plasma for Water Purification. Due to climate change, it becomes a serious issue if we do not treat the water resource carefully. We may end up using water with contamination from the enlivenment. Therefore, finding out a good way to improve water purification is an important topic. As we know that the discharge mechanism of an electric field can kill bacteria, viruses and other microgametes. When they pass through the high voltage electric field, the cell nucleus will be destroyed due to the electric shock from the plasma reaction system. But thermal plasma cannot be used to treat water directly, so Cold Atmospheric Pressure Plasmas is the method being applied in this study. In this research they focus on how pack bed discharge and distribute discharge are the keys to scaling up the plasma liquid interface.
To keep us in existence the earth needs at least three basic requirements, which are sunshine, air, and water. Not only does water play an important role in our bodies, but also the environment needs water to keep in balance. Since our water resource are coming from nature, using an efficient way of purification will be a challenge for the future.
