TREATMENT OF PRODUCED WATER

摘要

A method of treating produced water containing hydrocarbons includes introducing microbubbles of a lift gas into the produced water in a separation stage to float oil to a surface of the produced water. The top layer of oil is removed from the surface of the produced water. Microbubbles of an oxidizing gas are introduced into the produced water in an aeration stage to oxidize contaminants. Microbubbles of an ultra-violet light treated oxidizing gas are introduced into the produced water in an advanced oxidation stage to oxidize remaining contaminants.
