This summer I was a member of the SRSF Theory team. I researched the different variables that cause clogging of the subsurface injection filter as well as measured the effect on effluent turbidity and head loss. The stacked rapid sand filter was compared to the conventional downflow rapid sand filter.

I am was a member of the SRSF Theory team. We are redesigning redesigned and built the filter apparatus so that it better represents the Stacked Rapid Sand Filter. Several issues in designing the experimental apparatus include included keeping influent turbidity constant and reducing coagulant loss. We will test methods in order to later collect data that will eventually culminate in a model of SRSF implemented and tested PID control so that influent turbidity stayed at a constant value and I monitored influent turbidity and clay pump control to test whether PID control was effective. I created part of the Process Controller method file to run experiments efficiently. I also compiled and analyzed data on effluent turbidity and head loss to evaluate filter performance.
