ABSTRACT:
An aqueous slurry of spent drilling mud and/or produced water is diluted prior to free discharge into a body of receiving water by expelling a jet stream of such slurry into an open-ended submerged mixing conduit. The jet stream aspirates and entrains the surrounding water within the conduit and is then passed through a mixer stage prior to exiting the opposite end of the tube.
