Here’s some info on desalinization

Carlsbad Cal is building a plant which is slated to open in 2016, 16 years after the proposal was approved by the city. Administrative hearings and court processes in which environmental groups got several bites of the apple trying to shoot it down.
What happens to the salt?
The desalination plant typically uses three kilograms of seawater to produce 1 kilogram of fresh water. The extracted salt dissolves in the excess sea water used in the process to form so-called brine. The brine is returned to the sea where it is diluted again in its natural medium.
Can salt be recovered?
The usual desalination processes do not provide for such recovery. Whereas they concentrate seawater 1.5 times, recovery of salt would require seawater to be concentrated ten times. Under such conditions the first crystals would appear in the brine. This would require a lot of energy and cannot be justified on an economic standpoint. Today whenever a large surface area is available close to a sunny seashore, salt pans, which make use of solar energy, are still the best method of salt production.
Hey al gore. If Gorebull warming raises the sea level, then multiple desalinization plants should lower it. So no problem there.
The Carlsbad plant’s maximum output would be up to 10% of the county’s needs. If we build a few more we could take care of Imperial County and keep the agriculture going there.
San Diego is the driest county along the coast in California both in annual rainfall and underground water supply.
