A desalination plant can turn seawater into drinkable water?

Question

in theory a desalinisation plant can provide drinkable water to small countries that need fresh water? is that true? huh huh?

Answer 1

In addition to being expensive, they also pollute. They require energy to run (CO2 emissions), and they produce a lot of salt as a by-product. Usually the excess salt is just dumped back into the sea.

Answer 2

Yes, it is true. What a desalinization plant does is distill the water out of the salty solution it came from. The heat or energy source heats up the water to the point of steam and then captures the steam into a condensation tank, thus distilled water. It is pure H2O ready to drink or any other use. The problem with desalinization plants is the amount of energy expended to create the water. It has been economically impractical to pursue. Until our water from other sources becomes too scarce, I don't think we will seriously pursue desalinization. A nuclear power plant, like San Onofre on the California coast, could created electricity and at the same time capture the steam from the cooling tanks into condensation tanks. The uranium rods heat the water, creating steam that goes through the turbine generators creating electricity and then cools the water for recycling back to the cooling ponds. Instead of sending the condensed steam back to the cooling pond, they could capture it as distilled water for domestic use. I know it is doable, it is just a matter of whether Americans are prepared to pay for their water the way they pay for electricity.

Answer 3

Desalination plants (or desalinization, or just desal for short) can turn seawater into drinking water, yes. The problem is they're typically viewed as prohibitively expensive -- the initial cost is high, and operating costs are also fairly high. So while they do work, they're not always a good option, particularly for small countries which may not have the resources required to build and run such a plant.

Answer 4

I don't think so. If that were true, then why would governments not have done it already. Plus, there is the issue that salt isn't the only thing we have to take out of sea water to make it drinkable, its just the main one, so the media focus on that.

Then you've got to consider what effects the plant itself would have on the water...it produces byproducts which make further contaminate the water.

So sorry, but I don't think it would be possible.

Answer 5

you will possibly use "desalinator," in spite of the incontrovertible fact that it relies upon somewhat on the device. A nevertheless or an evaporator makes potable water with the aid of boiling and condensing, leaving the salt (brine) to be drained off from the boiler. A demineralizer replaces the cations in salt with a H+, and the anions with a OH-, leaving organic water.

Answer 6

Yes reverse osmosis works fine.

Answer 7

Sure, but it would cost too much.
