Fall 2016 Contributions

So far, our team has been working on designing the new EStARS filter into which the new 1 L/s plant would be fed. Much of this semester has been spent working with the previous EStaRS team's Mathcad file in order to determine which variables and equations will be most important to us as we make our new design. We are currently in the process of determining the head loss values for the new dimensions of the shorter filter. In addition, we are playing around with ideas on how to reduce the the height of the sand filter layers without compromising the efficiency of the filter.

Fall 2016 Goals

This semester, I am returning to the Enclosed Stacked Rapid Sand Filtration team (EStaRS) after a 1-year hiatus. This time around, we have been given the task of designing and fabricating a new EStarS filtration system in order to be used in conjunction with the newly built 1 L/s Plant. This semester, my team and I plan to analyze the feasibility of making a shorter EStarS filtration system with shorter sand filter layers in order to be used with the 1 L/s Plant. In addition, we hope to make a MathCAD analysis to determine necessary calculations for head loss, dimensions, etc. and create a corresponding AutoCAD design. Finally, the end goal is to be able to fabricate and test a new and highly functioning filtration system that eliminates the problems from the previous system that is able to be used with the 1 L/s plant.
