RESEARCH AREAS

Professor Long Nghiem’s current work focuses on the development of a membrane-based platform for resource recovery from wastewater and small-scale renewable-energy-driven seawater desalination technologies for remote coastal communities. His specific research interests include:

  • Membrane separation (including pressure driven processes, forward osmosis, membrane distillation, membrane electrolysis, facilitated transport membrane)
  • Membrane bioreactors
  • Membrane fabrication (including electrospinning, solvent casting, and phase inversion)
  • Removal of trace organic contaminants 
  • Water quality and treatment (including water recycling and seawater desalination)
  • Biosolids management
  • Anaerobic digestion of wastewater sludge and organic wastes
