If we can turn sewerage into drinkable water, why cant they make sea water drinkable?

Answer 1

Sewage is drinkable water that has organisms in it capable of making you sick, along with a few molecules that are bad for you. You filter out the organisms and neutralize the bad molecules and the result is drinking water with slightly more salts than before you neutralized everything. Seawater has to have the dissolved salts removed. This takes 100's of times more energy than simple filtration.

Answer 2

Actually they can. They have s type of generator right here in down town long beach that is able to turn sea water from the harbor into drinking water. But I do not know if they are actually using it.
