i hear there are water purification plants on some of the world's coasts, that are using water from the ocean for making clean water, via removing the salt from large amounts of sea water( making drinking water), and then returning the excess( brine), with high salt content, to the sea...i also hear there are lots of complaints about this--
if the complaints are due to the large amount of salt returned to the sea, i suggest that this sea-salt, or "brine", could be dehydrated( or evaporated, to make dry salt/produce steam), and then be reinserted at proper amounts, bringing the salt levels in the water returned to the ocean, back to the same amount as the water initially entering the plant--
by testing the value of salt in the water daily( as it enters the plant), the amount of salt in the water being returned to the sea can be equalized, any resulting excess salt, could then be sold to other countries, with desert, or dry, climates...like India, Africa, Afghanistan, Iraq, South africa, Egypt, Australia, ect...
in addition, i feel that, instead if a problem, an opportunity exists, and that these water desalination plants, are in fact, potential salt factories, or power stations, as well as water purification facilities, waiting to produce revenue...
power production--
although the concept of mega water-desalination is new, the concept of moving water inland, and diverting it over something to turn a shaft, that creates power, is not...i suggest this hydro-electric process could also be combined with a desalination plant, that produces fresh water--
if we use two large "well turbines"( an alternator placed in an underground stream of water), that are huge, one for the brine( waste), and one for the fresh water, each generating power, more yield can be gained from a process( desalination) that is already in use...and, in fact, any process in the facility that requires the movement of water is an opportunity for one, or more, water-cooled hydro-electric generators, or possibly a steam-driven electric turbine...if this concept is developed, it may yield a lot of good water for our world...a bit of power, and some salt to boot...
