Photocatalysis – Researchers at Beacon Research and
the University of Maryland’s Department of Civil and Environmental Engineering
have developed novel techniques to immobilize TiO2 onto various
substrates to assist with the disinfection of contaminated water. TiO2 and low power LEDs combine to
produce hydroxyl radicals, oxidants that destroy a wide range of pathogens.
Geotextiles – Professor Allen Davis’ laboratory at
the University of Maryland, College Park is a leader in the development of
bioretention areas to increase the capture rate of pollutants from storm water
runoff. Coupled with geotextiles, bioretention
offers an inexpensive and effective means of reducing the long-range dispersion
of heavy metals, excess nitrogen and phosphorous, all precursors to more
serious Chesapeake Bay contamination.
