Abstract

A method of remediating a water-based fluid includes the steps of providing a container providing a fluid cavity and organic, inorganic and biological remediation media within the cavity. The container is tubular and provides a linear flow direction, organic, inorganic and biological remediation media arranged in the cavity and configured to permit a water-based fluid within the cavity to simultaneously flow through the media. The organic, the inorganic and the biological remediation media are respectively configured to remove organic, inorganic and microbiological constituents. The organic, inorganic and biological remediation media are arranged within the cavity along the linear flow direction. Multiple cartridges are arranged within the cavity and spaced apart from one another. A predetermined flow rate of the water-based fluid through the cavity is set and it concurrently removes organic, inorganic and iodine-based biocide contaminants from the fluid within the cavity.

First claim

What is claimed is:

1. A method of remediating a water-based fluid, comprising the steps of:
providing a container having a fluid cavity, and organic, inorganic and biological remediation media is arranged within the cavity, wherein the container is tubular and provides a linear flow direction, organic, inorganic and biological remediation media arranged in the cavity and configured to permit a water-based fluid within the cavity to simultaneously flow through the media, wherein the organic, the inorganic and the biological remediation media are respectively configured to remove organic, inorganic and microbiological constituents, the organic, inorganic and biological remediation media arranged within the cavity along the linear flow direction, multiple cartridges arranged within the cavity and spaced apart from one another, wherein the cartridges are oriented along the linear flow path to provide unobstructed passages between the cartridges in the direction of the linear flow path, the biological remediation media is arranged closest to the outlet;
setting a predetermined flow rate of the water-based fluid through the cavity; and
concurrently removing organic, inorganic and iodine-based biocide contaminants from the fluid within the cavity.

2. The method according to claim 1 , wherein the concentration of iodine in the fluid is at least 4 mg/L.

3. The method according to claim 1 , wherein the pH of the fluid is approximately 7.0.

4. The method according to claim 1 , wherein the organic remediation media is an activated carbon, the inorganic remediation media is an ion exchange resin, and the biological remediation media is an iodine resin configured to elute molecular iodine.

5. A method of remediating a water-based fluid, comprising the steps of:
providing a container having a fluid cavity, and organic, inorganic and biological remediation media is arranged within the cavity, wherein the container is tubular and provides a linear flow direction, organic, inorganic and biological remediation media arranged in the cavity and configured to permit a water-based fluid within the cavity to simultaneously flow through the media in parallel without having to first flow serially through the media, wherein the organic, the inorganic and the biological remediation media are respectively configured to remove organic, inorganic and microbiological constituents, the organic, inorganic and biological remediation media arranged within the cavity along the linear flow direction;
setting a predetermined flow rate of the water-based fluid through the cavity; and
concurrently removing organic, inorganic and iodine-based biocide contaminants from the fluid within the cavity.
