Mobile submersible mixing apparatus
A mobile submersible mixer comprising a mobile platform, frame or chassis with a plurality of wheels, with one or more mixing jets or systems mounted thereon. The apparatus also may comprise an aeration system and real-time sampling system. The apparatus is introduced into a pit or tank, typically by rolling the mixer down a ramp into the pit or tank.
1. A system for mixing produced water, comprising:
a pit or tank containing produced water, said pit or tank comprising a liner and a ramp into the pit or tank;
a mobile submersible mixer, said mobile submersible mixer comprising a top, an open framework chassis with three or more tires attached thereto, and a mixing jet securely affixed to the top; and
a line attached to a point on the chassis;
wherein the mobile submersible mixer is adapted to roll down said ramp into said tank or pit containing produced water and is operable to mix the produced water when the mobile submersible mixer is fully submerged therein; and
further wherein the line is adapted to control the descent of the mobile submersible mixer down the ramp and to retrieve the mobile submersible mixer from the tank or pit.
2. The system of claim 1 , wherein there are four or more tires.
3. The system of claim 1 , wherein the tires are sand-filled tires.
