748 million people in the world do not have access to safe water. This is roughly one in ten of the world 's population. Every year, around 60 million children are born into homes without access to sanitation. Every year, around 60 million children are born into homes without access to sanitation. People -- especially those in water-starved parts of the world -- have been searching for fresh water solutions for centuries. Even in modern times, entire populations struggle with a cruel irony; they are surrounded by salt water, but lack drinking water. Desalination, desalinization, and desalinisation refer to any of several processes that remove some amount of salt and other minerals from saline water. Desalination/distillation is one of…show more content…
Distillation is perhaps the one water treatment technology that most completely reduces the widest range of drinking water contaminants. Without safe water or sanitation, people are trapped in a cycle of poverty and disease. Across the developing world, millions of women are wasting precious time collecting dirty water, children are dying from preventable diarrheal diseases, and communities have open sewers running through them. Salt water is desalinated to produce fresh water suitable for human consumption or irrigation. Salt water makes a person thirstier and eventually would make you suffer from dehydration. 2.5 billion People in the world do not have access to adequate sanitation, one in three of the world’s population. Using desalination can help lower this number by a ton because it can open these people to a cleaner and more sanitized life. There are varying degrees of salinity in water, which affects the difficulty and expense of treatment, and the level of saline is typically measured in parts per million (ppm). The U.S. Geological Survey provides an outline of what constitutes saline water: 1,000 ppm – 3,000 ppm is low salinity, 3,000 ppm – 10,000 ppm is moderate salinity, and 10,000 ppm – 35,000 ppm is high salinity. Water that contains saline levels less than 1,000 ppm is generally considered fresh water, and is safe to drink and use for household and agricultural purposes. For a reference point, typical ocean water contains about 35,000
