    Like the title suggests. Is filtering salt water a viable option to get fresh water? If so, what are some techniques for separating salt water from sea salt?

    Filtering no, use a solar still.

    Sorry I did not add this image earlier, working on a borrowed computer whilst mine in for repair! Other stills can also be used to produce drinkable water from sea/salt water. With the solar still you can use urine or dirty water or salt water or flora/vegetation as in this image. The container in the center collects the good clean water.

    I don't know the process of filtering salt water to fresh water but I have tasted a fresh water that comes from filtering water that comes from the sea. It is done here in my country of one of the famous hotel near the beach.

    there is a technique to boiling saltwater to collect the steam which then condenses into fresh water, this you can drink.
    I have never done it myself as I don't live by the coast but I have seen it done.

    Thanks for letting me know about this. I'll definitely be looking up that technique on Google.

    Wow, this diagram actually makes it much more easier to understand. Thanks for coming back and sharing this picture. I'll definitely be trying out this technique later today

    What's the name of this hotel might I ask? If you could tell me I wouldn't mind looking this up.

    I don't think you can filter sea water to come up with a drinkable version. It's hard to explain but according to my knowledge of chemistry, a solution needs a drastic measure to separate the elements. Anyway, I had seen how the people in one coastal province here produce salt from sea water. They have a vat where they cook the seawater by boiling. The water will evaporate and the salt will remain. And since what you need is fresh water, you have to catch the evaporating steam by placing a sturdy blanket on top of the vat with the hem of the blanket directly pointed on a basin. The evaporating steam will be caught by the blanket and eventually collect the condensation to the basin.
