## Abstract

A fluid treatment device is disclosed. The device includes a vessel having a fluid entrance and exit. Within the vessel hollow fiber of nano-porous material are arranged so as to define two volumes separated by the nano-porous material. In one embodiment the fluid, air, passes up the center of the hollow fiber drying as the air contacts the inner walls of the fiber. The device is purged by stopping the flow through the device and allowing the air pressure that builds up between the fibers to be released through the nano-porous material.

## Claims

### Claim 1

A method of removing impurities from a fluid comprising the steps of:
pumping at least one fluid into an inlet of a vessel and out of at least one outlet of said vessel, the vessel having at least one first and at least one second volume separated by at least one element formed of porous material adapted to adsorb at least one impurity from said fluid, wherein pumping fluid through said vessel increases the pressure of the fluid in the or each first and second volume;
closing a valve adjacent said outlet thereby preventing said fluid flowing out of said outlet; and
exposing said inlet to lower pressure thereby allowing fluid in said first and second volumes to pass through said inlet.

### Claim 2 (depends on 1)

A method according to claim 1, wherein said fluid in said vessel is only able to transfer between said first and second volumes by flowing through the pores in said element.

### Claim 3 (depends on 1)

A method according to claim 1, wherein said fluid is pumped into at least one aperture extending at least partially into said element.

### Claim 4 (depends on 1)

A method according to claim 1, wherein said element is heated.

### Claim 5 (depends on 1)

A method according to claim 1, wherein said fluid is pumped through at least one filter placed within said vessel.

### Claim 6 (depends on 1)

A method according to claim 1, wherein said porous material is a nano-porous material.

### Claim 7

A fluid treatment device comprising:
a vessel having at least one access for allowing a fluid to enter and leave said vessel; and
at least one element having at least one aperture extending through said element wherein said element is formed from at least one porous material adapted to adsorb at least one impurity from said fluid.

### Claim 8 (depends on 7)

The treatment device of claim 7, further comprising at least one seal wherein at least one said seal and the or each said element define a plurality of volumes within said vessel.

### Claim 9 (depends on 8)

The treatment device of claim 8, wherein at least one said seal and the or each said element define at least one volume which is only in communication with at least one said access through pores in said porous material.

### Claim 10 (depends on 7)

The treatment device of claim 7, wherein said aperture in said element does not extend through said element.

### Claim 11 (depends on 7)

A treatment device in accordance with claim 7, further comprising at least one heating element engaged with at least one said element.

### Claim 12 (depends on 7)

A treatment device in accordance with claim 7, further comprising at least one filter placed within said vessel.

### Claim 13 (depends on 7)

A treatment device in accordance with claim 7, wherein at least one said access comprises at least one fluid input portion and at least one fluid output portion.

### Claim 14 (depends on 7)

A treatment device in accordance with claim 7, wherein said porous material is a nano-porous material.
