Plummer, Jeanine D.
The goal of this project was to reduce trihalomethane precursors (organic carbon) in municipal drinking water for regulatory compliance. A bench scale filtration column with Greensand, GreensandPlus, and/or anthracite media was designed to mimic treatment plant conditions. Experiments were conducted to evaluate changes to process variables, including chlorine dose, pH, and coagulant dose. Based on results and literature research, it was recommended that the treatment plant upgrade to GreensandPlus and reduce the pre-chlorination dose to optimize organic carbon removal.
