Tyson Pham Posted Sunday, September 17, 2017 at 7:29 PM I am doing a project on water filtration, I need to know what are the disciplines of water filtration. I am wondering about how environmental and mechanical engineer is necessary for the filtration. 1 Answers Greg Pearson, National Academy of Engineering Posted Monday, September 18, 2017 at 10:26 AM Tyson: What grade students is the project aimed at? Is the project part of a particular curriculum, such as Engineering is Elementary? I will find someone to help you, once you provide a bit more info on what you need.
