filters are available in different pore sizes. therefore we can use appropriate pore size filter to separatesalt from salt solution. this type of filteration is called ultrafiltration, nanofilteration. reverse osmosis , a kind of filteration under pressure , is also used.
There are a number of ways to remove salts from water:
-----------------
1. Distillation. The salt water is repeatedly evaporated and condensed in a "reflux" condenser.
At some point, determined by the design, the condensed water in the reflux condenser is tapped
off. If the condenser is sufficiently efficient (that's easy in the case of inorganic salts)
the water is very pure (distilled water).
2. Sequential freezing. Here salty water flows over a rotating drum that is cooled below the
freezing point of water. Some of the salty water freezes out on the drum. Water has a rather
complicated crystal structure that prevents inclusions of most salts in the crystal lattice.
So pure water crystallizes out on the drum. There are a number of mechanical/chemical devices
to rinse off the layer of pure water ice that forms. This category of purification is used
in restaurants and bars. In such establishments you will see that the ice cubes are crystal
clear with no inclusions of air like you observe in home-made ice cubes. In addition to the
salts, dissolved gases are removed from the water. The process is very efficient for water that is not too
salty.
3. Reverse osmosis. If one separates salty water and pure water by a membrane that allows
water to pass through it (but not any of the dissolved ions) the natural course of events
is that water from the "pure" water side will diffuse through the membrane to dilute the
salty water. This transport comes to equilibrium when the salt concentration on both sides
of the membrane is the same. This process is called osmosis. In reverse osmosis a high
pressure is applied the salty side of the water separated by the membrane that will allow
water to pass, but not the ions. If the pressure is high enough the water is "squeezed" out
of the salty side into the pure water side. The pressures required are rather high and the
membranes are usually not 100% efficient, so in commercial systems there are some engineering
design problems to make the membrane sufficiently mechanically strong to withstand the
pressure difference across the membrane, and a series of membranes may be required to
improve the overall efficiency.
4. There are certain polymeric filters that exchange H(+1) ions for cationic ions M(+n)
and OH(-1) ions for anionic ions A(-m). These remove the salts for H(+1) and OH(-1). Of
course, here one may need to be concerned about the final pH of the effluent water. I do
not think that this method is widely used.
You can use a purification system. you can put the saltwater in a 2 literbottle and put a tube on top where the cap goes and you attach another literbottle but on a higher place. you heat up your 2 litterbottle that has saltwater it should evaporize and then it condenses back into liquid and falls into your other bottle. The salt should stay in the first litterbottle. Hard to explain i wish i was able to draw a picture When salt water is boiled, all the salt will crystallize at the bottom of the container and water will evaporate from the container.
Collect the condensation, and you have salt-free water.

Or in two words: "distil it"!
It is very easy to purify/filter your water. Just either buy a water filter jug and cartridge or water purifying tablets, or, if you want do it the old fashioned way, boil the water which gets rid of any harmful things.
You could filter sea water by heating it up and then letting it cool leaving you with salt, or if you wanted to filter the elements you can use electrolysis, this means you send electricity through the sea water and separate it into oxygen, hydrogen and chlorine, hope this helps
The cheapest (but more complex) way is to use reverse osmosis, which produces two water streams... one with less salt, and one very concentrated in salt (perhaps toxically so) and "floaties" that need treatment.
A more expensive (but simpler) way is evaporation, which leaves the salt behind (and usually kills the "floaties"). Also called distillation.
Another way is to use mixed bed deionization, or just one bed each of cation and anion exchange resin. For small amounts of water (and low salt levels), this can be inexpensive. These columns can be regenerated, and there are companies that do this by service exchanging regenerated vessels for exhausted ones.
I can not think of a way but u can get salt from salt water by evaporating the water because only the liquids will evaporate and salt is a solid not a liquid. Sorry I could not be of more help. BBWYes!!! If you boil the water enough, the salt will stick to the pan, and then you'll have distilled clean fresh water.
salt in the water can be reomved by reverse osmosis. In reverse osmosis, solvent is flown from the solution
A bit but definitely not all you need to evaporate the water to get the salt out
The water will evaporate and salt will be left ... so unless you want salt it is imposible to clean salt water with the sun
Fresh water ..... lol
the difference between salt water and fresh water is that salt water is from the ocean and fresh water is water that hasn't gotten to the ocean and so the water is clean, And you can only drink fresh water not salt water
Yes. They are fresh water in the sense of without salt. However, if by fresh you mean clean, no they are generally full of bacteria and bad stuff for you.
Soap is not necessary for removing salt from your hands. Salt is very easy to clean off your hands with just water.
The water will evaporate and salt will be left ... so unless you want salt it is imposible to clean salt water with the sun
It is not true; salt is corrosive.
Yes. It is safe to clean an infected toe with hot salt water.
Yes. It will clean them with the salt.
both actually, salt can kill slugs and can clean your thruoght like if you have soar thruoght than you can gargle salt water and can clean out the bacteria
Clean, salt water.
It is not recommended; after drying salt remain on the skin.
Use salt water, as was used in the Boston Molasses Tragedy of 1919. Warm salt water works best.
evaporation technics
They will both evaporate but the water with salt in it will leave the salt behind and it will once again become clean water. It will also leave other impurities out.
No, it is not recommended to use salt water to clean a cut. Salt water may cause further irritation and delay the healing process. It is best to clean a cut with mild soap and water or an antiseptic solution, and keep it covered with a sterile dressing.
clean the tank and while you are doing that put it in a small bowl but with enough room to swim with fresh water but make sure that if it is a fresh water its in fresh water if it is salt water it is in salt water
