摘要

The present invention relates to nano-membrane, and a method of producing fresh water used in the pretreatment process of a step for obtaining the water (fresh water), eating to remove salts present in the water. The nano-membrane made by the present invention is a two-scale caused the number concentrated under relatively low drive pressure in the sea water desalination process, it is possible to achieve the salt removal for removing sulfate ions at a high level, the scale such as calcium sulfate salt It can be suppressed. Thus, it is possible to maintain the permeability of the nano-membranes to a high state. Thus, using a nano-membranes of the present invention, to increase the recovery rate of the sea water desalination system can be improved and the production energy efficiency of the system.
