Fall 2016 Contributions

As part of the StaRS Filter Theory team, I am developing a mathematical model to explain filtration and write a paper on our results. In describing granular media filtration, a capillary model was developed, where sand pores were aggregated as many capillary tubes running down the length of the filter. I am creating the washer model, the next iteration of the model, where particle capture is pictured as "washers" of flocs at pore constrictions.

Spring 2016 Contributions

I am continuing continued my work on the StaRS Filter Theory team to reach our goal of creating a mathematical model. I am designing designed a tube flocculator to facilitate creating small flocs similar to the influent water in AguaClara plants. Additionally, I advise advised the High Rate Sedimentation - Plate Settler and Rapid Mix Contact Chamber team. As team lead, I created and organized training sessions for the team to advance AguaClara's research.

Fall 2015 Contributions

As team lead, I worked with the StaRS Filter Theory team and advised the Spectrophotometer and Floc Hopper Probe teams. As part of the StaRS Filter Theory team, I designed a filter system that implemented the new injection system.  I measured the filtration performance based on head loss and effluent turbidity. I also worked with PID control to create a constant influent turbidity.
