if you collect sea water and it contains pebbles, sand and salt how would you separate it ?

Answer 1

You could filter out the pebbles and sand with a cloth or paper filter but the salt you would have to remover by evaporation

Answer 2

Well... the pebbles and sand can be separated by running through a good filter. The salt would need a bit more work -- boiling it and collecting the water vapor into a separate container would result in pure water (in that separate container)

Answer 3

Mechanically! First filter out the undissolved solid matter with a sieve or other filtering method, and run the salt water through a reverse osmosis filtration system to remove the dissolved salt and other minerals.

Answer 4

Erm, with a filter probably, something like a muslin cloth should do the trick.
As for the salt, boil the filtered water and collect the steam in a condenser, the salt residue will be left behind.

Answer 5

I would sieve the pebbles, then evaporate the sea water to leave the salt behind.

Answer 6

Leave it in a container for a few days and it will settle out,,take the water and boil it,,collect the steam and allow it to condense,,the salt will remain in the pan,,the cadenced steam will turn into fresh water

Answer 7

If you want just the water without the salt and all that crap, I would boil it and collect the vapors. You would probably need a large quantity of water to begin with.

Answer 8

Strainer will remove stones and sand. Distillation will remove the salt, leaving pure water.

Answer 9

as the others have said... boiling helps... but if u want it to be purely distilled, then consider doing some reverse osmosis (NOT A COMMERCIAL WAY!) to eliminate even that tinge of minerals left... to make it potable though, u have to add some essential minerals like magnesium, sodium, potassium and the like in well defined quantities to the distilled water obtained... :)

Answer 10

pour in water to dissolve salt ant put through thin funnel to separte sand and pebbles am i correct or was that too easy????
