Treatment of oil recovery process waste water |
| abstract |
Abstract of the Disclosure Waste water from the steam recovery of bitumen from subterranean oil deposits is purified to enable it to be reused to generate further steam, by reverse osmosis using a thin-film composite membrane comprising gamma-irradiated sulfonated poly(2,6-dimethyl-1,4-phenylene oxide) (SPPO). The invention is broadly applicable to the treatment of any waste water stream containing organic chemical- and dissolved minerals-contamination using any high energy irradiated thin-film composite SPPO membrane. |
