THE METHOD FOR PRODUCING DRINKING WATER USING DEEP SEA WATER

摘要

The prevent invention relates to a method for producing drinking water by using deep sea water. The method for producing drinking water by using deep sea water comprises: a pretreatment step for filtering deep sea water by using a filter; a first desalinization step for obtaining first desalinization water and enriched water by desalinizing the filtered deep sea water using a reverse osmosis membrane; a second desalinization step for obtaining second desalinization water from the first desalinization water by using a separation membrane for fresh water; a reenrichment step for obtaining highly enriched salt water, calcium sulfate, and sodium chloride by enriching the enriched water; and an input step for putting the highly enriched salt water and calcium sulfate into the second desalinization water. By the method of the present invention, drinking water which is alkalescent in pH, is safe from boron, and is tasty by containing rich minerals, is produced.
