ABSTRACT
Canadian oil spill response regulations require collection of all liquids from a response operation, this involves many vessels and frequent trips to shore to dispose of collected liquids, which mainly comprise of water. Onsite treatment of decanted oily seawater would benefit operations by addressing vessel storage and trip frequency issues. Membrane technology has proven effective at treating oily wastewater from various industries; therefore, is a good candidate for onsite treatment of wastewater generated from response operations. In this study, oily seawater treatment efficiency of a pilot-scale physical membrane filtration and a bench-scale membrane bioreactor (MBR) were compared. Three main parameters were considered, total petroleum hydrocarbon, petroleum hydrocarbon fractions, and polycyclic aromatic hydrocarbons. 99.1 % and 98.2 % TPH removal efficiency were achieved by MBR (93.1 ppm initial oil concentration) and membrane filtration (28.3 ppm initial oil concentration), respectively. The MBR showed more promise than membrane filtration for onsite treatment of decanted wastewater.
