desalination Flashcards
reverse osmosis
the movement of fresh water through a semipermeable
membrane when pressure is applied to a solution
saline water
contains significant amounts of
dissolved salts
saline water ratings
Freshwater : <1,000 ppm
Slightly saline water :1,000-3000ppm
Moderately saline water : 3,000-10,000ppm
Highly saline water :10,000 35,000ppm
Ocean water about 35,000 ppm
dead sea
280,000ppm of salt
2 ways to desalinate water
run a still and reverse osmosis
distilled water?
water boiled and condensed without minerals and salt
Calcium, Magnesium, Sodium
is reverse osmosis efficient?
40% of water is wasted in SMALL UNITS and expensive at large scales
