Summer 2010 Contributions

During summer 2010 I had the pleasure of working on the Stacked Rapid Sand Filtration team. I assisted in building a bench scale model of the stacked filter, controling the influent raw water turbidity and keeping its turbidity as consistent as possible, running a plethora of experiments of varied parameters such as filtration velocity and dosage, and successfully backwashing the system by sequentially fluidizing individual sand layers. I also contributed in conducting a performance comparison to a conventional single layer filter system of the same depth as an individual layer of our stacked filtration system (20 cm), and in adding pressure sensors to the apparatus to provide a more complete comparison. The original apparatus consisted of four filter layers in a white 4" I.D. PVC pipe, and I assisted in replacing it right before the Fall semester with a clear PVC pipe of the same diameter but with six filter layers. This clear pipe allowed us to run visual experients in Fall 2010.

Fall 2010 Contributions

During Fall 2010 I have continued working on the Stacked Rapid Sand Filtration Team.
