Helping chlorine-eating bacteria clean up toxic waste

... trichloroethylene (TCE). They do this by removing chlorine atoms from molecules and leaving less-toxic compounds behind. But D. ethenogenes strains work well at some sites and not so well at others, and nobody knows for sure why. In fact, very little is understood about how these organisms live and breath...

New UD technology removes viruses from drinking water

...cess, this natural organic material can react with chlorine to produce a variety of toxic chemicals called disinfection byproducts. "Our iron-based technology can help ensure drinking-water safety by reducing microbial pathogens and disinfection byproducts simultaneously," Chiu noted. Applications in a...
