How to Remove Salt from Sea Water
The process of removing salt from sea water is known as desalination, which helps to create fresh drinking water. The simplest way to remove salt from sea water is from letting the water set in the sun. This method is only helpful if you just want the salt since the water will be absorbed into the atmosphere. A second method is to send the water to a desalination plant where the water is heated, condensed, and purified by professionals. For a possible method of removing the salt yourself, you can use the reverse osmosis system. The system is a filtration process the forces a solution through using pressure, separating the majority of sediment from the water. Does this Spark an idea?

1
Get a sediment pre-filter, which is used in advanced water filter systems and can be found at nearly any retail store (See Resources). Keep in mind that creating a reverse osmosis system can be costly, but is one of the only methods for removing salt from water at home. The pre-filter helps to stop contamination from dust, dirt and any other outside source.

2
Use a second pre-filter to ensure to remove any possible chemicals within the water. Place the second filter beneath the first pre-filter.

3
Order a reverse osmosis membrane online or buy one from any other retailer (See Resources). This film composite is set up below the filters and is where the filtered water will be pressure forced into.
-
4
Use a carbon post filter after the water runs through the membrane to double-ensure that all chemicals are caught in the process.
-
5
Run the water through the system using a hose or tube so that the water quickly goes through the filters and enters the membrane with high pressure. The system will remove about 98 percent of the salt. No product on the market can guarantee that 100 percent of the contaminants will be removed.

Tips & Warnings
Try looking for a pre-built reverse osmosis system to save yourself time and possibly money.
The water will be safe to drink or use after the reverse osmosis process, but to guarantee purification, you'll need to send the water to a desalination plant.
