Abstract

Systems for water treatment may include an evaporation unit, wherein the evaporation unit may comprise: a first blower; a spacer, wherein the spacer may be fluidly coupled to the first blower; wherein the evaporation unit may be configured to aerate and evaporate water; and a drying tunnel, wherein the drying tunnel may comprise: a second blower, wherein the second blower may be fluidly coupled to an end of the drying tunnel; a heater coupled to an exterior surface of the drying tunnel; nozzles disposed between the heater and the second blower; and a chamber configured to collect solids; wherein the drying tunnel may be configured to evaporate water.

Claims

1. A system for aerating, evaporating, and treating a contaminated body of water comprising:

at least one evaporation unit, wherein the at least one evaporation unit comprises;

a first blower configured to suction an air mass proximate the contaminated body of water;

a spacer fluidly coupled to the first blower;

a diffuser fluidly coupled to the spacer; and

,

at least one arm coupled to and extending away from the diffuser, wherein the at least one arm is hollow and is configured to allow the air mass to pass through the at least one arm;

at least one drying tunnel, wherein the at least one drying tunnel comprises;

a second blower, wherein the second blower is fluidly coupled to an end of the at least one drying tunnel;

a heater coupled to the at least one drying tunnel;

at least one nozzle configured to be a coupled to the contaminated body of water, the at least one nozzle disposed between the heater and the second blower; and

a chamber configured to collect solids.

2. The system of claim 1, wherein the at least one evaporation unit is configured to be positioned in one of a) a storage tank configured to contain the contaminated body of water and b) a storage pit configured to contain the contaminated body of water.

3. The system of claim 1, wherein at least one of the spacer and the first blower is configured to be partially submerged in the contaminated body of water.

4. The system of claim 2, wherein the first blower is configured to be positioned on top of the storage tank.

5. The system of claim 1, wherein the at least one drying tunnel is positioned at an angle from about 30°

to about 90°

relative to horizontal.

6. A system for aerating, evaporating, and treating a contaminated body of water comprising:

at least one of a storage tank and a storage pit configured to contain the contaminated body of water;

at least one evaporation unit configured to be positioned in one of the at least one of the storage tank and the storage pit, wherein each evaporation unit comprises;

a first blower configured to suction an air mass proximate the contaminated body of water;

a spacer fluidly coupled to the first blower;

a diffuser fluidly coupled to the spacer; and

,

at least one arm coupled to and extending away from the diffuser, wherein the at least one arm is hollow and is configured to allow the air mass to pass through the at least one arm; and

at least one drying tunnel, wherein the at least one drying tunnel comprises;

a second blower, wherein the second blower is fluidly coupled to an end of the at least one drying tunnel;

a heater coupled to the at least one drying tunnel;

at least one nozzle configured to be a coupled to the contaminated body of water, the at least one nozzle disposed between the heater and the second blower; and

a chamber configured to collect solids.

7. The system of claim 6, wherein at least one of the first blower and the second blower is configured to move over 100,000 cubic feet of air per minute.

8. The system of claim 6, wherein at least one of the spacer and the first blower is configured to be partially submerged in the contaminated body of water.

9. The system of claim 8, wherein at least one of the plurality of drying tunnels is positioned at an angle from about 30°

to about 90°

relative to horizontal.

10. The system of claim 6, wherein the at least one evaporation unit comprises a plurality of evaporation units.

11. The system of claim 6, wherein the at least one drying tunnel comprises a plurality of drying tunnels.

12. A system for aerating, evaporating, and treating a contaminated body of water comprising:

at least one evaporation unit configured to be positioned at least partially within the contaminated body of water, wherein the evaporation unit comprises;

a first blower configured to suction an air mass proximate the contaminated body of water; and

a spacer fluidly coupled to the first blower; and

at least one drying tunnel, wherein the drying tunnel comprises;

a hollow conduit with a proximal end and a distal end spaced apart from the proximal end;

a second blower fluidly coupled to the proximal end of the at least one drying tunnel and configured to provide a stream of air into the at least one drying tunnel;

a heater coupled the at least one drying tunnel;

at least one nozzle configured to be a coupled to the contaminated body of water, the at least one nozzle disposed between the heater and the second blower and configured to provide the contaminated water into the at least one drying tunnel and the stream of air passing therethrough; and

,

a chamber coupled to and disposed exterior to the at least one drying tunnel, the chamber configured to collect solids falling out of solution from the contaminated water as the contaminated water is evaporated.

13. The system of claim 12, wherein the at least one evaporation unit further comprises:

a diffuser fluidly coupled to the spacer; and

,

at least one arm coupled to and extending away from the diffuser, wherein the at least one arm is hollow and is configured to allow the air mass to pass through the at least one arm.

14. The system of claim 12, wherein at least one of the first blower and the second blower is configured to move over 100,000 cubic feet of air per minute.

15. The system of claim 12, wherein at least one of the second blower and the at least one drying tunnel has an inner diameter from about 8 feet to about 12 feet.

16. The system of claim 12, wherein a length of the at least one drying tunnel is about 50 feet to about 200 feet.

17. The system of claim 12, wherein the at least one drying tunnel is disposed on a trailer.

18. The system of claim 12, wherein the chamber is positioned between the second blower and the at least one nozzle.

19. The system of claim 12, wherein the at least one drying tunnel is positioned at an angle from about 30°

to about 90°

relative to horizontal.
