Global Nuclear Fuel (GNF), a joint venture of GE, Toshiba and Hitachi, has succeeded in making wastewater plant changes that have reduced water usage by 25 million gallons annually at its headquarters in Wilmington, North Carolina, USA.

The new energy efficient wastewater system avoids nearly 80 tons per year of CO2 emissions, and realizes annual savings of US$160,000 in water and energy use charges. This reduction forms part of GE’s overall ecomagination commitment to reduce its water footprint by 20% in 2012.

The water savings at the GE Hitachi Nuclear Energy (GEH) site were a result of reusing wastewater effluent with ZeeWeed membrane bioreactor (MBR) technology as a make-up water source to operate cooling towers, which would otherwise withdraw raw water obtained from local groundwater wells to accomplish the same.
