Can we filter ocean water?

Question

Can we filter ocean water?

Answer 1

Yes. Reverse osmosis takes the salt out. But you need high pressure pumps to force the water through the filter, because the natural flow would force the fresh water into the salty side. That is where the "reverse" in the name "reverse osmosis" comes from. And generating all the energy needed to run the pumps would cause more global warming and cost a lot of money. Right now, your water if FREE. What you are paying for the the pipes and pumps and reservoirs to deliver it. If you added the cost of making it from sea water with reverse osmosis, your cost would go WAY up.

Answer 2

Yes crystallisation can remove the salt while filteration makes nit clearer.
