This is my first semester on AguaClara, and I am a member of the depth vs. surface sand filtration team. My team's overall goal is to research, analyze, and compare the differing features of a conventional rapid sand filter and AguaClara's stacked rapid sand filter. The main difference between the two systems is the location at which the water is injected--at the surface vs. into the sand bed, respectively. We intend to explore the pros and cons of these two different methods of water injection, analyzing how they affect the head loss and other important components of the system. Much of our work will be in literature research, but we also intend to work with the filter currently set up in the lab in order to carry out experiments and test our theories.
