A method to concentrate organic matter and a mineral ingredient from deep-ocean water or bottom of the sea depths bedrock water

摘要

A method of concentrating organic matters and mineral components from deep seawater or deep sea rock-floor water is provided to improve production efficiency of the drinking water by concentrating organic matters and mineral components from salt water discharged from a process of producing drinking water from the collected deep seawater or deep sea rock-floor water by collecting deep seawater or deep sea rock-floor water. A method of concentrating organic matters and mineral components from deep seawater or deep sea rock-floor water sequentially comprises the steps of: collecting deep seawater of a water depth of 200 m or less or deep sea rock-floor water; heating the collected deep seawater or deep sea rock-floor water to a temperature of 20 to 30 deg.C; performing a pre-treatment process of filtering the heated deep seawater or deep sea rock-floor water by a filtration process using sand filtration, microfiltration, ultrafiltration, nanofiltration, or combinations thereof; performing a first reverse osmosis filtration process of filtering the pre-treated water; sending the filtered water to a drinking water production process, and desalinating concentrated salt water that has not been filtered by the first reverse osmosis filtration process; and performing a second reverse osmosis filtration process of concentrating organic matters and mineral components from the desalinated salt water.
