Abstract
A mobile water re-use system can include a chemical treatment apparatus, at least one weir tank in fluid communication with the chemical treatment apparatus, and two or more settling tanks in fluid communication with each other and at least one of the settling tanks in fluid communication with the weir tank. The weir tank can have a first end, a second end, an internal chamber, and a plurality of baffles that induce turbulent flow of fluid through the internal chamber. The settling tanks can provide, promote, facilitate, result in, and/or induce laminar flow of fluid through at least a portion of the internal chamber. Weir tanks, settling tanks, and method of treating flowback and produced water are also described.
Claims39
A mobile water re-use system, comprising:
- a chemical treatment apparatus;
- at least one weir tank in fluid communication with the chemical treatment apparatus, the weir tank comprising a first end, a second end, an internal chamber, and a plurality of baffles that induce turbulent flow of fluid through the internal chamber;
- and
- two or more settling tanks in fluid communication with each other, wherein at least one of the settling tanks is in fluid communication with the weir tank, and wherein the settling tanks provide laminar flow of fluid through the internal chamber.
A method of treating flowback and produced water, comprising:
- a) transferring flowback and produced water to a chemical treatment apparatus;
- b) mixing treatment chemicals with the flowback and produced water;
- c) transferring the mixture of treatment chemicals and flowback and produced water to a weir tank comprising a first end, a second end, an internal chamber, and a plurality of baffles positioned throughout the internal chamber to induce turbulent flow;
- d) transferring the mixture of treatment chemicals and flowback and produced water to a first settling tank that provides laminar flow;
- and
- e) transferring the mixture of treatment chemicals and flowback and produced water to a second settling tank that provides laminar flow.
A method of treating flowback and produced water, comprising:
- a) transferring flowback and produced water to a chemical treatment apparatus;
- b) mixing the flowback and produced water with treatment chemicals;
- c) transferring the mixture of treatment chemicals and flowback and produced water to a first weir tank comprising a first end, a second end, an internal chamber, and a plurality of baffles positioned throughout the internal chamber to induce turbulent flow through the internal chamber;
- d) transferring the mixture of treatment chemicals and flowback and produced water back to the chemical treatment apparatus;
- e) mixing the flowback and produced water with additional treatment chemicals;
- f) transferring the mixture of treatment chemicals and flowback and produced water to a second weir tank comprising a first end, a second end, an internal chamber, and a plurality of baffles positioned throughout the internal chamber to induce turbulent flow through the internal chamber;
- g) transferring the mixture of treatment chemicals and flowback and produced water to a first settling tank that provides laminar flow;
- and
- h) transferring the mixture of treatment chemicals and flowback and produced water to a second settling tank that provides laminar flow.
A weir tank for treating flowback and produced water, comprising:
- a first end;
- a second end;
- an internal chamber;
- and
- a plurality of baffles that extend up from a bottom portion of the internal chamber, the baffles extending up from the bottom portion of the internal chamber comprising an arm that extends out in a direction toward the first end of the weir tank,
- wherein the plurality of baffles induce turbulent flow of fluid through the internal chamber.
A settling tank for treating flowback and produced water, comprising:
- a first end comprising a fluid inlet port and a fluid outlet port;
- a second end;
- an internal chamber;
- an internal feed line positioned within the internal chamber, the internal feed line having a first end connected to the fluid outlet port and a second end having an opening that extends out toward the second end of the settling tank;
- and
- a baffle plate positioned between the opening of the internal feed line and the first end of the settling tank,
- wherein the settling tank provides laminar flow of fluid through the internal chamber.
