摘要： A reverse osmosis apparatus for a seawater desalination system is provided. The reverse osmosis apparatus includes: a barrel in which a plurality of reverse osmosis membrane units with a reverse osmosis membrane wrapped in each reverse osmosis membrane unit are arranged; an inflow and outflow portion provided at a first end of the barrel and connected to a seawater inlet a high salinity water outlet; a partition wall configured to partition an inner space of the inflow and outflow portion into a first stage and a second stage; and a transport space portion provided in a second end of the barrel and configured to guide water being moved from a plurality of reverse osmosis membrane units arranged in the first stage to move to a plurality of reverse osmosis membrane units arranged at the second stage, wherein part of seawater fed to the inflow and outflow portion is fed around the tubes in the barrel and insulates the plurality of reverse osmosis membrane units in the barrel from external high temperature while being moved, and flows into the transport space portion.

摘要： A reverse osmosis system for a seawater desalination system is provided. The reverse osmosis system includes: a high pressure pump configured to supply pretreated seawater at high pressure; a reverse osmosis apparatus configured to desalinate by reverse osmosis the seawater supplied from the high pressure pump; and a pressure exchanger connected to a high salinity water outlet of the reverse osmosis apparatus and configured to recover part of pressure of discharged high salinity water to the reverse osmosis apparatus, wherein the reverse osmosis apparatus includes: a vessel in which a plurality of reverse osmosis membrane units are arranged in a first stage and a second stage; an inflow and outflow portion coupled to a first end of the vessel and connected to a seawater inlet and a high salinity water outlet; a partition wall configured to partition an inner space of the inflow and outflow portion into two spaces; and a transport space portion coupled to a second end of the vessel and configured to guide the seawater moved from a plurality of reverse osmosis membrane units arranged in the first stage to move to a plurality of reverse osmosis membrane units arranged in the second stage.
