<\/a><\/p>\nMost of the United States has, or can gain access to, ample supplies of fresh water for drinking purposes. But, fresh water can be in short supply in some parts of the country (and world). And, as the population continues to grow, shortages of fresh water will occur more often, if only in certain locations. In some areas, salt water (from the ocean, for instance) is being turned into freshwater for drinking.<\/p>\n
What do we mean by “saline water?” Water that is saline contains significant amounts (referred to as “concentrations”) of dissolved salts. In this case, the concentration is the amount (by weight) of salt in water, as expressed in “parts per million” (ppm). If water has a concentration of 10,000 ppm of dissolved salts, then one percent (10,000 divided by 1,000,000) of the weight of the water comes from dissolved salts.<\/p>\n
Here are our parameters for saline water:<\/p>\n
Fresh water – Less than 1,000 ppm
\nSlightly saline water – From 1,000 ppm to 3,000 ppm
\nModerately saline water – From 3,000 ppm to 10,000 ppm
\nHighly saline water – From 10,000 ppm to 35,000 ppm<\/p>\n
By the way, ocean water contains about 35,000 ppm of salt.<\/p>\n
