Abstract
We provide a process for treatment of produced water, including but not limited to water produced by a 'steam flood' process for extraction of oil from oil sands, including the removal of color from the water. This removal may be accomplished through addition of color-removal polymers and flocculents. This process may also be useful for other water treatment processes including reverse osmosis and filtration.
