Abstract

A water treatment method is provided for helping to partially or completely remove sodium and methane gas from water. In the method, water is combined with a reactant that is formulated to combine with the sodium in the water and form a compound. The water and compound are then passed through a bed of media for helping to separate the compound from the water. The method also includes aerating the water to release gases contained therein by breaking the water into microdroplets by passing it through a screen. Additionally, the method may include a step wherein the water is passed through an acidic resin for facilitating a cation exchange where additional sodium is removed. A water treatment apparatus for performing the method is also provided.

Claims (16)

1. A liquid filtration system, comprising:

a first vessel including

upper and lower ends,

an inlet proximate said upper end for feeding liquid into said first vessel, wherein said inlet is in fluid communication with a spray arm for aerating said liquid and a source of reactant formulated for at least partially removing sodium from said liquid through adsorption, and

an outlet proximate said lower end; and

a second vessel including

upper and lower ends,

an inlet for receiving liquid from said first vessel outlet and feeding liquid into said second vessel proximate its lower end, wherein said inlet is in fluid communication with a distribution pipe for dispersing liquid within said second vessel,

media within said second vessel for separating compounds from said liquid, and

an outlet for removing treated liquid.

2. The liquid filtration system of claim 1 wherein first vessel further includes a screen underneath said spray arm for breaking said liquid into microdroplets as said liquid passes through said screen.

3. The liquid filtration system of claim 1 further comprising a third vessel for containing said source of reactant.

4. The liquid filtration system of claim 1 wherein said reactant is selected from a group consisting of acetic acid, magnesium hydroxide, magnesium oxide, magnesium sulfate, gypsum, lime, calcite and combinations thereof.

5. The liquid filtration system of claim 1 wherein said first and second vessels are placed on portable skids.

6. The system of claim 1 wherein said media is selected from a group consisting of sand, gravel, clay, and manufactured plastic beads.

7. The system of claim 1 wherein said media is perlite.
