Abstract
Methods of deoiling oily water such as SAGD and frac produce water. The oily water is treated with a natural coagulant selected from tannins and chitosan. A cationic and/or anionic flocculant may also be added to the treated oily water. The thus treated oily water may be subjected to conventional mechanical oil separation techniques such as hydrocyclonic separation, dissolved air flotation, entrapped air flotation, induced gas flotation, gravity filters, reverse osmosis filters, API, or Voraxial® bulk separators and the like.
