ABSTRACT:
A method of purifying waste water from oil well rigs in order that the water may be made suitable for reuse on the rig or disposed of conventionally is disclosed. The method incorporates a series of aerators and corresponding collection tanks to first aerate, then collect, the waste water a number of times. In each collection tank, sediment precipitates to the bottom of the tank, permitting the clearer water to overflow, or to be skimmed, from the collection tank. A soluble aluminum salt is added to the waste water at an initial stage of aeration in order to coagulate waste particles within the water and form solid precipitates which then settle to the tank bottom, permitting the clearer water to pass on to subsequent aerators and sedimentation tanks, until ultimately, the water may be disposed of without polluting or contaminating the environment.
