### Claim 6 (depends on 1)

The system of claim 1, further comprising an injection port configured to receive a substance to add to the fluid.

### Claim 7 (depends on 6)

The system of claim 6, wherein the substance comprises at least one of a coalescing agent, a polymer, and an oxidizing agent.

### Claim 8 (depends on 6)

The system of claim 6, wherein the substance includes one or more from a group that consists of a permanganate, a potassium permanganate, a hydrogen peroxide, a soap, a surfactant, a soluble oxidizing agent, a polymer, a coalescing agent, and a flocculent.

### Claim 9 (depends on 6)

The system of claim 6, wherein the injection port is at a location before the fluid is received at the separator.

### Claim 10 (depends on 2)

The system of claim 2, further comprising an injection port configured to receive a substance to add to the fluid,
wherein the injection port is at a location before the pump.

### Claim 11 (depends on 3)

The system of claim 3, wherein the receiving vessel includes a mixing volume operable to receive a portion of a content of the first chamber of the receiving vessel and a portion of a content of the second chamber of the receiving vessel so that the fluid from the first chamber and the fluid from the second chamber will come in contact with one another prior to exiting at the one or more output openings of the receiving vessel.

### Claim 12 (depends on 1)

The system of claim 1, wherein the one or more constituents of the fluid includes at least one of (i) one or more salts, (ii) drill cuttings, and (iii) sand.

### Claim 13 (depends on 1)

The system of claim 1, wherein the one or more constituents of the fluid includes at least one of (i) flowback water, (ii) produced water, and (iii) waste water.

### Claim 14 (depends on 1)

The system of claim 1, wherein the fluid comprises water and the one or more constituents of the fluid comprises salt.
