LOW-TEMPERATURE TREATMENT AND MANUFACTURING TECHNOLOGY FOR PRODUCTION OF MINERAL DRINKING (EDIBLE) WATER AND HIGH MINERAL CONTENT SALTY WATER WITH RAW DEEP SEA WATER BY THE SYSTEM INCLUDING ELECTRODIALYZER, REVERSE OSMOSIS UNIT AND SPECIAL MIXING DEVICE UNDER THE LIMITED LOW TEMPERATURE OPERATION CONDITION

摘要

Provided is a method for preparing low temperature mineral drinking water and high concentration low temperature brine from deep sea water by using reverse osmosis and electrodialysis. The method comprises the step of controlling the ratio of mineral of deep sea water by using both reverse osmosis and electrodialysis. Preferably, the process is carried out at 10-15 deg.C or less; the ratio of magnesium (Mg), calcium (Ca), sodium (Na) and potassium (K) is controlled to be 2-5 : 1 : 1 : 1 in the case of the low temperature mineral drinking water.
