    Abstract: It is to provide a process for manufacturing potable water from a liquid to be treated, such as seawater by using forward osmosis membrane, wherein the solution after the separation of water from dilute draw solution diluted by the migration of water from the liquid to be treated, is stably regenerated and reutilized and an apparatus therefor, and the process and apparatus are a process for manufacturing potable water which comprises, a forward osmosis step wherein a liquid of which solvent is water is allowed to contact with a draw solution produced by dissolving a prescribed amount of a volatile material in water through a semi-permeable membrane, and water in said liquid is allowed to migrate to said draw solution through said semi-permeable membrane, a distillation step wherein a dilute draw solution having been diluted with water which was produced in said step is adjusted to a prescribed temperature, and then is delivered to a distillation column where gas comprising the volatile material and water vapor is discharged from the top of the column and potable water is discharged from the bottom of the column, and a cooling • regeneration step wherein said draw solution is regenerated by cooling said gas and an apparatus therefor.

    Abstract translation: 它是提供一种通过使用正向渗透膜从待处理液体（如海水）制造饮用水的方法，其中将水从稀释的溶液中分离后的溶液通过水从待处理的液体中的迁移而稀释 ，稳定再生再利用及其设备，该方法和装置是一种制造饮用水的方法，该方法和装置包括：正向渗透步骤，其中使溶剂为水的液体与通过溶解 通过半透膜在水中规定量的挥发性物质，并使所述液体中的水通过所述半透膜迁移到所述溶液中，蒸馏步骤，其中用水稀释的稀释溶液，其为 在所述步骤中制备的产物被调节到规定的温度，然后被输送到蒸馏塔，其中包含挥发性的气体 材料和水蒸气从塔顶排出，饮用水从塔的底部排出，并且冷却再生步骤，其中通过冷却所述气体再生所述的溶液及其设备。
