This National Science Foundation (NSF) CFDA 47.041 Engineering program award to Villanova University provides $199,991 to advance the understanding of how bromine (Br) and iodine (I) variability in drinking water sources contribute to the formation of disinfection byproducts (DBPs). The project aims to: 1) develop geospatial and statistical methods to assess iodine inputs to drinking water sources, and 2) perform targeted source water sampling to assess the spatial and temporal variability of...
This $262,158 Project Grant award from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems (CBET) will fund research at the South Dakota School of Mines and Technology to develop advanced oxidation processes for controlling the formation of iodinated disinfection byproducts (I-DBPs) in drinking water treatment.
The key objectives are to: 1) investigate the use of advanced oxidation processes like ferrate, ozone, and UV to optimize the oxidation of iodine and iodinated compounds to the nontoxic iodate; 2) integrate these advanced oxidation processes with conventional water treatment methods to minimize the formation of both I-DBPs and regulated disinfection byproducts; and 3) develop new analytical methods to measure iodine species and I-DBPs. This research aims to provide fundamental knowledge to guide the design of more effective water treatment processes for mitigating the formation of highly toxic I-DBPs. The project will also provide research training and mentoring opportunities for graduate and undergraduate students at the South Dakota School of Mines and Technology and South Dakota State University.
