Silver nanoparticles have a wide array of uses, one of which is to treat drinking water for harmful bacteria and viruses. But do silver nanoparticles also kill off potentially beneficial bacteria or cause other harmful effects to water-based ecosystems? A new paper from a team of University of Missouri College of Engineering researchers says that’s not the case.
Viruses are infamous during cold and flu season, but research from the Civil and Environmental Engineering Department shows their effectiveness, especially when paired with more commonly-used methods, in destroying bacteria during wastewater treatment.
As organisms go, the microbes that are the heroes of this healthy wetland tale are among the toughest and tiniest. They can live in an environment that lacks both oxygen and sunlight, and roughly four hundred of them will fit into the period at the end of this sentence.

University of Missouri engineering researchers are developing a portable wastewater treatment system for military bases that they believe ultimately will produce water pure enough to drink. The portable treatment system will screen the wastewater with advanced membranes as well as disinfect it chemically, producing reusable water that would save what often is a scarce resource […]
A University of Missouri researcher has found an increasingly popular nanomaterial kills bacteria used to clean the nation’s wastewater, and is launching a follow-up study to determine the levels at which it becomes toxic. Zhiqiang Hu, an MU civil and environmental engineering assistant professor, found in a National Science Foundation-sponsored study that silver nanoparticles destroy […]
A Mizzou Engineering student team is devising a new type of septic tank that would better protect the environment. About 25 percent of the U.S. population—and 40 percent of new developments—use septic systems, according to U.S. Environmental Protection Agency Web site statistics. But wastewater treated and released by many septic systems still contains nutrients, primarily […]
Two new faculty members have joined the MU College of Engineering, strengthening the college’s education force while fortifying its foundations for groundbreaking research. Zhiqiang Hu, a wastewater treatment expert, started work last August as an assistant professor in the CoE’s civil and environmental engineering department. Nam–Jung Kim, a nanotechnology researcher, became the CoE mechanical and […]
