Development of treatment train based on green technologies for removal and recovery of naphthenic acids from oil-sand process affected wastewater
Each day large volumes of oil sands process-affected water (OSPW) are being produced during the extraction of bitumen in oil sands industry in northern Alberta. OSPW contains different polyaromatic hydrocarbons (PAHs), bitumen, as well as naphthenic acids (NAs), which not only are the major source o...
