New technique could help decontaminate oilsands process water

New technology developed by engineers at the University of Alberta shows potential in cleaning and decontaminating process water from oilsands production. The process relies on ozonation and biofilters to remove organic compounds from contaminated water. The study, published in Science of the Total Environment, demonstrates that the method, previously used to clean pharmaceutical waste water, efficiently removes naphthenic acids, considered to be one of the main contaminants in oilsands process water.
