Innovative Research For Phosphorus Recovery In Freshwater Sediments, An Experimental Framework, John D. Collins
Innovative Research For Phosphorus Recovery In Freshwater Sediments, An Experimental Framework, John D. Collins
Honors College Theses
Phosphorus, a finite element, is necessary for all living organisms and directly impacts biota growth as well as productivity in freshwaters. The demand for phosphorus is continually increasing, but the supply of phosphorus is continually decreasing. In response to depleting resources, phosphorus in surface water sediments is being explored as a sustainable solution to the forecasted phosphorus shortage. Phosphorus in sediments is generally bound to oxidized iron (Fe3+) forming iron phosphate complexes. This form of phosphorus is released when iron reduces to Fe2+ in anaerobic environments. Under such conditions, soluble phosphorus (i.e., orthophosphate) may then be recovered using compounds that …

Assessing The Ability Of Arduino-Based Sensor Systems To Monitor Changes In Water Quality, Josiah Hacker
Honors College Theses
Access to safe water is vital to public health. While developed countries like the United States are recognized as having reliable and safe water, many small water utilities struggle with supplying consistent water quality. Technicians of these utilities will periodically test water samples from the influent and throughout the distribution system. However, this laborious and costly process does not capture sudden changes in influent water quality due to environmental conditions or pipes breaking in the distribution system. Here I show how an Arduino-based sensor can be used as a real-time, low-cost monitor of water quality parameters. Specifically, I developed a …
