Waste liquid solidification system and method

1. A waste liquid solidification system comprising:

a chamber at least partially enclosing a volume;

a liquid outlet positioned to spray a liquid into the volume;

a powder outlet adjacent the liquid outlet positioned to discharge a super-absorbent polymer powder into the volume; and

an ejection system for pushing the solid waste out of the chamber, wherein the ejection system includes a pressure generator to pressurize the volume of the chamber to force the solid waste out of the chamber,

wherein the liquid outlet and powder outlet are configured such that the liquid and the super-absorbent polymer powder undergo airborne mixing within the volume enclosed by the chamber to create a solid waste, and

wherein an outlet from the pressure generator is coupled to the chamber separately from the liquid outlet and separately from the powder outlet.

2. The waste liquid solidification system of claim 1 , wherein the ejection system further includes

an outlet valve through which the solid waste is forced by operation of the pressure generator to pressurize the volume of the chamber.

3. A waste liquid solidification system comprising:

a chamber at least partially enclosing a volume;

a liquid outlet positioned to spray a liquid into the volume;

a powder outlet adjacent the liquid outlet positioned to discharge a super-absorbent polymer powder into the volume, wherein the liquid outlet and powder outlet are configured such that the liquid and the super-absorbent polymer powder undergo airborne mixing within the volume enclosed by the chamber to create a solid waste; and

an ejection system for pushing the solid waste out of the chamber, wherein the ejection system includes

an outlet valve; and

a mechanical apparatus positioned inside the chamber and operable to physically engage the solid waste to force the solid waste through the outlet valve.

4. The waste liquid solidification system of claim 3 , wherein the mechanical apparatus is a piston.

5. The waste liquid solidification system of claim 1 , wherein evacuation of the solid waste out of the chamber is automatically controlled by a control system.

6. The waste liquid solidification system of claim 1 , further comprising a powder filtration system coupled to the chamber.

7. The waste liquid solidification system of claim 6 , further comprising a powder reservoir coupled to the powder outlet for supplying the super-absorbent polymer to the volume, wherein the powder reservoir is coupled to the powder filtration system.

8. A waste liquid solidification system comprising:

a chamber at least partially enclosing a volume;

a first liquid outlet positioned in the chamber to spray waste liquid into the volume;

a second liquid outlet positioned in the chamber to spray waste liquid into the volume such that the first and second liquid outlets define overlapping spray patterns;

a powder outlet coupled with a supply of super-absorbent polymer powder and positioned adjacent the first and second liquid outlets to discharge the super-absorbent polymer powder into the volume; and

an ejection system for pushing the solid waste out of the chamber, wherein the ejection system includes a pressure generator to pressurize the volume of the chamber to force the solid waste out of the chamber,

wherein the first and second liquid outlets and the powder outlet are configured such that the liquid and the super-absorbent polymer powder undergo airborne mixing within the volume enclosed by the chamber to create a solid waste, and

wherein an outlet from the pressure generator is coupled to the chamber separately from the liquid outlet and separately from the powder outlet.

9. The waste liquid solidification system of claim 8 , wherein the powder outlet is located below the first and second liquid outlets.

10. The waste liquid solidification system of claim 8 , wherein the overlapping spray patterns of the first and second liquid outlets encompass an entire cross-section of the chamber.

11. The waste liquid solidification system of claim 8 , wherein the overlapping spray patterns of the first and second liquid outlets are overlapping conical spray patterns.

12. The waste liquid solidification system of claim 8 , wherein the chamber defines an elongate axial direction having a top end and a bottom end, and wherein the first liquid outlet, the second liquid outlet, and the powder outlet are all positioned nearer the top end than the bottom end.

13. The waste liquid solidification system of claim 8 , wherein the ejection system further includes

an outlet valve through which the solid waste is forced by operation of the pressure generator to pressurize the volume of the chamber.

14. The waste liquid solidification system of claim 8 , wherein evacuation of the solid waste out of the chamber is automatically controlled by a control system.

15. The waste liquid solidification system of claim 8 , further comprising a powder filtration system coupled to the chamber.

16. The waste liquid solidification system of claim 15 , further comprising a powder reservoir coupled to the powder outlet for supplying the super-absorbent polymer to the volume, wherein the powder reservoir is coupled to the powder filtration system.
