The feasibility of a nanotechnology-based hydrocarbon and other contaminants removal pressure
filtration device has been demonstrated for dewatering industrial utility vaults and substructures
for discharge to local storm drains. The use of the filter device facilitated compliance of utility
companies with the General National Pollutant Discharge Elimination System (NPDES) Permit for
Discharges from Utility Vaults and Substructures to Waters of the United States. The filter device,
employing agglomerated oleophilic nanomaterials demonstrated the removal of dissolved priority
pollutants, total suspended solids, and hexane extractable materials below U.S. Environmental Protection Agency criteria with an overall efficiency of 97.4 percent. Overall reduction per contaminant averaged 90 percent. © 2016 Wiley Periodicals, Inc. Reprinted with permission.
