6. The method of claim 1 , wherein unloading the first portable bulk material container from the blender unit to a position outside of the blender unit comprises unloading the first portable bulk material container from the blender unit directly to a trailer for transporting the first portable bulk material container away from the location of the blender unit.

7. The method of claim 4 , wherein unloading the first portable bulk material container from the blender unit to a position outside of the blender unit comprises unloading the first portable bulk material container from the blender unit directly to the trailer that transported the first portable bulk material container to the location of the blender unit.

8. The method of claim 2 , wherein the first device is positioned in a loading area on the first side of the blender unit, and the second device is positioned in an unloading area on the second side of the blender unit.

9. The method of claim 8 , wherein at least one of the loading area and the unloading area comprises a pad or a platform.

10. The method of claim 1 , wherein at least one of the first and second devices comprises a forklift.

11. The method of claim 1 , wherein the treatment fluid is a well treatment fluid.

12. The method of claim 1 , wherein the single trailer-mounted or skid-mounted component further has a mixing compartment in which the bulk material is mixed with the one or more fluids, wherein the mixing compartment has the solid material inlet, the fluid inlet, and the fluid outlet.

13. The method of claim 12 , wherein the first portable bulk material container is loaded onto a support structure of the blender unit, wherein the mixing compartment is located below the support structure of the blender unit, and wherein the support structure is part of the single trailer-mounted or skid-mounted component.

14. The method of claim 13 , wherein the support structure of the blender unit is accessible on a first side thereof and on a second side thereof.

15. The method of claim 14 , wherein the support structure has a plurality of spaces thereon each configured to receive a bulk material container, wherein each of the plurality of spaces are accessible by the first device on the first side of the support structure and by the second device on the second side of the support structure.

16. A method, comprising:

loading a first portable bulk material container from a position outside of a blender unit onto the blender unit using a first device, the blender unit comprising a single trailer-mounted or skid-mounted component, wherein the single trailer-mounted or skid-mounted component has at least a mixer of the blender unit;

wherein the first portable bulk material container is loaded onto the single trailer-mounted or skid-mounted component of the blender unit;

producing a treatment fluid via the mixer of the blender unit by mixing bulk material released from the first portable bulk material container with at least one fluid input separately to the mixer;

unloading the first portable bulk material container from the blender unit to a position outside of the blender unit using a second device after at least some of the bulk material within the first portable bulk material container has been consumed by the blender unit; and

loading a second portable bulk material container from a position outside of the blender unit onto the blender unit in place of the first portable bulk material container using the first device.

17. A method, comprising:

loading a first portable bulk material container from a position outside of a blender unit onto the blender unit using a first device, wherein the blender unit is configured to produce a treatment fluid, the blender unit comprising a single trailer-mounted or skid-mounted component, wherein the single trailer-mounted or skid-mounted component has at least a mixer configured to produce the treatment fluid, and wherein the first portable bulk material container is loaded onto the single trailer-mounted or skid-mounted component of the blender unit;

outputting the treatment fluid produced by the blender unit from the blender unit;

unloading the first portable bulk material container from the blender unit to a position outside of the blender unit using a second device after at least some of the bulk material within the first portable bulk material container has been consumed by the blender unit;

loading a second portable bulk material container from a position outside of the blender unit onto the blender unit in place of the first portable bulk material container using the first device; and

maintaining the output of the treatment fluid at or above a predetermined flow rate from the blender unit throughout the unloading of the first portable bulk material container and the loading of the second portable bulk material container.

18. The method of claim 17 , further comprising releasing bulk material from at least one other portable bulk material container into the mixer during the unloading of the first portable bulk material container and the loading of the second portable bulk material container to maintain the output of the treatment fluid.

19. The method of claim 1 , wherein the single trailer-mounted or skid-mounted component further has:

a hopper coupled to the solid material inlet;

a support frame having a plurality of spaces thereon each configured to receive a bulk material container; and

at least one gravity feed outlet having a first end located proximate one or more of the plurality of spaces of the support frame and a second end proximate the hopper, wherein the at least one gravity feed outlet routes bulk material from at least one bulk material container on the support frame directly into the hopper.

20. The method of claim 19 , wherein the at least one gravity feed outlet is a plurality of gravity feed outlets each having a first end located proximate a corresponding one of the plurality of spaces of the support frame and a second end proximate the hopper, wherein the plurality of gravity feed outlets route bulk material from bulk material containers on the support frame directly into the hopper.
