Interest Areas

Say Kee Ong’s research interests are in the fate and transport of pollutants in engineered and natural systems, sustainable water and wastewater treatment and reuse systems, and hazardous waste management.


Research Projects

  • Sustainable wastewater and water reuse systems with emphasis on recovery of nutrients and useful products
  • Sorption and degradation of micro-pollutants and removal of heavy metals from soils, surface waters and in wastewater treatment systems
  • Progressive freeze concentration (PFC) process for water recovery and salt concentration
  • Membrane bioreactors (MBR) and biological aerated filters (BAF) for wastewater treatment and micro-pollutants removal
  • Bioremediation of petroleum-contaminated and former manufactured gas plant sites and application of natural attenuation
