Spring 2015 Contributions

This semester I will be working again on the Enclosed Stacked Rapid Sand Filter Team (EStaRS). Our goals for the semester are to conduct multiple filtration and backwash runs, to modify the cap design, and to design a new backwash siphon. Towards the end of the semester, a new inlet system was developed and designed to be implemented into our filter. We worked to design and fabricate this system and introduce it into our filter. This system was designed with the intention of removing the need for slotted pipes, which are seen as expensive to fabricate and maybe sources of error in the filtration process.

This semester I will be working on the Enclosed Stacked Rapid Sand Filter Team (EStaRS). Our goals for the semester are to ensure that the model functions properly and that it is built in the most efficient way possible.

Spring 2014 End of Semester Contributions

In the end, we were able to create a functioning web-based guide. We were able to incorporate PHP code into the HTML form in order to generate a results page. One of the problems we ran into was that the AguaClara web-server was not PHP enabled. We were able to combat this by operating an offline test server called MAMP. This provided us with a means to test out the mechanisms of the guide. The Water Treatment Technology Selection Guide we have developed only involves the surface water case to date. Some alterations the guide moving forward would be to expand the guide to include the ground water case, further research the decentralized water treatment options, and the integrate it with the Plant Cost Calculator and the AguaClara design engine.
