It cannot be used directly as drinking water because of the excessive salt content of more than 90 percent of the world's waters.
Technology for obtaining drinking water by removing salt from seawater for increased drinking water demand due to low precipitation, adverse climatic conditions, rapid urbanization and industrialization can be preferred in case of necessity conditions.
In reverse osmosis technology, the solutions are pumped under high pressure to purify the water by the salt and other contaminants. It is possible to say that recent developments in reverse osmosis technology have made the process of obtaining drinking water from seawater more effective and cost-effective.
With the latest technology now available, seawater can be purified with better quality and simply by reverse osmosis, at a much lower cost than distillation and similar methods.
