How do you filter salt water to make it drinkable?

that's a tough one... maybe you could come up with some way to boil it and trap the steam...

One way to do that for relatively small volumes of water is to force the sea water through a special membrane filter under high pressure. The filter membrane must be constructed so that its holes are large enough to just pass a water molecule, but not large enough to pass metal\nmolecules, salt molecules, algae, etc. The result would be fresh clean water with a lot of brine solution left in the pressurized tank that needs to be dumped.\n\nAnother process which is more poractical for large volumes of fresh water production is electrolisis. In that process, electrical current is passed through the water to break it down into its basic elements such as hydrogen and oxygen (and all the other junk that is left over).\n\nOnce the hydrogen and oxygen are collected and recombined, the result is pure fresh water. Again, the vat or tank holding the original sea water now has a heavy brine solution which must be disposed of somehow. Most any use of sea water to produce fresh water will generate a lot of salty brine by-product that could poison sweet earth in the vicinity if it is merely dumped.

i suppose the question i ask is have you actually ever done this?\n\nto seperate sand and water obviously you pour some water in a beaker with your sample and stir it, you filter the solution using a glass funnel and a filter paper.  you take the filter paper after you have finished and open it up and let it dry with the sand on, you take the water from the filtrate beaker and leave it to evaporate in a watchglass and then scrape the salt off.

If they are insoluble, just dissolve the salt, then filter the solution, then dry it. Pure salt!

when u boil water it evaporates....into a steam and leaves the container...if its salt water the salt will still remain in the container

To create water from saltwater, you could\n- boil or evaporate the saltwater and collect the vapor using a distilling contraption (e.g., put a plastic bag over the pot and catch the condensate)--this is the most practical way\n- use osmosis to separate the water from the saltwater, but this would be extremely expensive and require a lot of membranes/filters\n\nA heat source could be the sun, a fire, an energy plant, or anything else producing heat (geothermal, coal, nuclear, etc.).  More heat produces desalinated water faster.\nTo create more water faster, use a bigger heat source.

are you trying to turn saltwater back into separate salt and water? you need to heat the saltwater which will make the water evaporate. The salt won't evaporate so it'll stay in the container. If you need the water, you'll need to have a surface to let it condense on

Through evaporation, the water evaporates into the air and leaves the salt behind.\n\nWhen the water in the air condenses and comes back to earth as rain or snow or dew, it is again fresh water until it flows into a body of saltwater where it again mixes with the salt.\n\nSalt can also be removed through a variety of chemical and/or electrolytic "desalination" processes, but I assume you mean naturally.\n\nThe principal methods of mass conversion of salt water to fresh water (for providing drinking water in a desert environment or onboard a ship at sea) is done through either distillation, in which the salt water is boiled leaving the salt behind and the steam recondensed to form liquid water, or through a process called osmosis where the water flows through a membrane or material that the salt will not pass through.\n\n=== EDIT ===\n\nYes, a bit of research confirms that the principal method of converting saltwater to freshawater onboard a ship is either a flash-type evaporator (primarily used on older ships and nuclear powered ships) or a reverse-osmosis plant (used on more modern ships).  Both types are also used on US Navy bases where freshwater is not readily available.\n\nThe evaporator basically pre-heats the saltwater to near boiling, and then injects it into a vacuum chamber where it immediately flashes into steam except for a small amount of "brine" left over -- the steam is run through cooled pipes where it condenses into water, and the leftover brine is pumped back overboard.\n\nThe reverse-osmosis uses high pressures to force the water through a membrane which the salt cannot pass through.  Again, the leftover "brine" is pumped back into the ocean since it is just seawater with some of the water removed.

You will need Chlorine gas. Due to the common ion effect the salt(Sodium Chloride) will precipitate out leaving the fresh water.\nMaterials Needed:\nChlorine gas\nSalt Water

Distill it.\n\nIn cooking, supposedly you can put a piece of raw potato (sometimes, the hint says a piece of lettuce) in food that's too salty and it takes the salt out.  But I don't know if that works.  I'd go with distillation.  \n\nDistillation is where you boil a liquid and then catch the vapor and condense it.  In the case of salt water, the vapor would be plain water with nothing dissolved in it (the salt gets left behind in whatever you use to boil the liquid in.)  Distillation is also used to make an alcoholic liquid more alcoholic.  I guess the alcohol gets vaporized and condensed.

salt water DOESNT WORK...alum..its like a seasoning kinda u can get it at almost any grocery store (a white powder) just dab a bit on it and wash ur hands really good cuz u dont want to get it in ur eyes and keep ur mouth open for it to dry on and it will be gone in a few days (unless they are really bad then a week or so?)
