## Abstract

An apparatus for treating frac water may include a vacuum container to support a vacuum, a heating device to heat the vacuum container, a spiral auger to rotate to separate the frac water being positioned within the vacuum container, a condenser to condense the water vapor to liquid water, a second vacuum chamber to receive the liquid water and a storage container to store the liquid water.

## Claims

### Claim 1

An apparatus for treating frac water, comprising:
a vacuum container to support a vacuum;
a heating device to heat the vacuum container;
a spiral auger to rotate to separate the frac water being positioned within the vacuum container;
wherein the vacuum container maintains a sufficient vacuum to boil water at approximately 100° F. and to form water vapor;
a condenser to condense the water vapor to liquid water;
a second vacuum chamber to receive the liquid water; and
a storage container to store the liquid water.

### Claim 2 (depends on 1)

An apparatus for treating frac water as in claim 1, wherein the vacuum chamber includes a substantially circular cross-section.

### Claim 3 (depends on 1)

An apparatus for treating frac water as in claim 1, wherein the vacuum chamber includes a input port to receive the frac water.

### Claim 4 (depends on 1)

An apparatus for treating frac water as in claim 1, wherein the vacuum chamber includes a first output port to discharge the debris.

### Claim 5 (depends on 1)

An apparatus for treating frac water as in claim 1, wherein the vacuum chamber includes a second output port to discharge the water vapor.

### Claim 6 (depends on 1)

An apparatus for treating frac water as in claim 1, wherein a first passageway connects the vacuum chamber and the condenser chamber.

### Claim 7 (depends on 1)

An apparatus for treating frac water as in claim 1, wherein a second passageway connects the second vacuum chamber and the condenser chamber.
