Did you know that bubbles can clean water? Specifically, dissolved air flotation (DAF) and ultrasound are two methods of making water safer with bubbles. DAF can be used to replace sedimentation in municipal drinking water treatment. Large particles are typically settled out using gravity, but with DAF, bubbles are produced by an oxygen tank pumping air into the bottom of a basin and small particles attach to the sides of the bubbles. The bubbles rise to the top of the basin and the particles are swept off the surface of the water by a skimmer.
Recently I had the unique opportunity to interview renowned climate scientist Michael Oppenheimer. We met at the Hubbard Brook Annual Conference following his motivational speech. Dr. Oppenheimer is not only a professor of Geo-Sciences and International Affairs at Princeton, but also is a former member of the Environmental Defense Fund, and has an active role in the International Panel on Climate Change. He attained an undergraduate degree in Chemistry and a PhD in Chemical Physics, but is also versed in Atomic and Molecular Astrophysics and has even taught Astronomy at Harvard. Oppenheimer is able to speak about climate change in such a way that he has been a guest on several significant shows such as Oprah Winfrey, ABC News, and the Colbert Report. Aside from his credentials Dr. Oppenheimer is actually a very humble and inspiring person. Once you speak to him you will find he is quite delightful.
A Finnish University recently discovered the benefits of crystallization, or freezing water in order to purify it. Essentially, these scientists found that the upper layer of ice from a lake in Finland was nearly ten times cleaner than the water beneath. In addition, ice that had formed more slowly was noticeably cleaner than rapidly formed ice. This event called crystallization can only occur with the presence of a solvent and solute, such as water and salt. A professor from Lappeenranta University of Technology (LUT) made the statement below regarding the study. Continue reading “Clean as Ice”
The ELF (Education and Leadership Fellows for Sustainability) program at my University (SUNY at Buffalo) was recently featured in the UB Reporter. While at the event I had the pleasure of conversing with President Tripathi on some ideas I had for sustainability on campus. He shared some useful advice on how to succeed in University that I definitely will apply to my own career here at UB.
