Abstract : The services provided under this contract include both theoretical and experimental research for development of an appropriate technology for treatment of petroleum hydrocarbons in source water for reverse osmosis (RO) systems. This report evaluates and screens the candidate technologies identified during the literature review in accordance with the approved Technology Evaluation Plan. A short-list of technologies that warrant further study is recommended to be carried forward to the experimental phase. The contamination problems due to petroleum hydrocarbons have been long recognized. However, the treatment technologies available for treatment of petroleum contaminated media are still very limited. Major limitations relative to treatment of petroleum hydrocarbons include: exact chemical composition is not defined; aerobic treatment processes are not effective for breaking down heavy petroleum hydrocarbons; anaerobic treatment processes are slow; and physical/chemical treatment processes are expensive and there is usually additional waste produced during treatment of the contaminated media.
