Abstract

A door for a settling tank is provided, including a suction port for connection to a suction pipe within the settling tank; a discharge port positioned below the suction port, for connection to a discharge pipe within the settling tank, and for receiving a pipe providing discharge from a discharge source; an overflow port positioned adjacent to the suction port; and a frac fill port.

Claims (28)

1. A settling tank, comprising:

a removable door for allowing access into the settling tank, the removable door comprising:

i) a suction port; and

ii) a discharge port;

wherein the discharge port is in fluid communication with a discharge source external to the settling tank and to a discharge pipe within the settling tank, the discharge pipe ending at a position lower than the discharge port; and

wherein the suction port is in fluid communication with a water storage vessel exterior to the settling tank, and to a suction pipe within the settling tank, the suction pipe extending upwardly from the removable door, the suction pipe ending at a suction inlet.

2. The settling tank of claim 1 , wherein the discharge pipe ends at a discharge outlet with a deflection plate.

3. The settling tank of claim 2 , wherein the removable door further comprises:

iii) an overflow port, the overflow port connected to a condensation overflow pipe having a condensate inlet, the condensate inlet positioned above the suction inlet.

4. The settling tank of claim 3 , wherein the overflow port is positioned adjacent to the suction port.

5. The settling tank of claim 1 , wherein the removable door further comprises

a frac fill port.

6. A settling tank, comprising:

a door for allowing access into the settling tank, the door comprising:

a suction port; and

a discharge port;

a discharge pipe within the settling tank; and

a suction pipe within the settling tank, the suction pipe extending upwardly from the door and ending at a suction inlet in the settling tank,

wherein

the discharge port is in fluid communication with a discharge source external to the settling tank and to the discharge pipe; and

the suction port is in fluid communication with a water storage vessel exterior to the settling tank and to the suction pipe.

7. The settling tank of claim 6 , wherein the discharge pipe ends at a position lower than the discharge port.

8. The settling tank of claim 6 , wherein the discharge pipe ends at a discharge outlet with a deflection plate in the settling tank.

9. The settling tank of claim 6 , wherein the door further comprises:

an overflow port, the overflow port connected to a condensation overflow pipe in the settling tank having a condensate inlet in the settling tank, the condensate inlet positioned above the suction inlet.

10. The settling tank of claim 6 , wherein the door further comprises:

a frac fill port.

11. The settling tank of claim 6 , wherein the door is removable from the settling tank.
