PROBLEM TO BE SOLVED: To achieve a seawater desalination apparatus capable of producing drinking water from seawater by 1 liter or more for 5 minutes using a reverse osmosis membrane, and in which installation at a small vessel and at a small island not capable of obtaining electric power, and the maintaining use, movement and maintenance are facilitated as well.SOLUTION: Using a small motor 3 and a booster pump 5 capable of starting with a lithium ion battery 4, high pressure of 4.5 Mpa or more is applied, and seawater 10 is passed through a reverse osmosis membrane 2 charged in a pressure resisting vessel 1, thus salinity is removed to secure drinking water. Further, the exchange of parts and the easiness of maintenance by the compacting are achieved, a power generating system by a solar panel 16 is combined, thus a battery can be charged, and a seawater desalination apparatus usable at any time and any place is made possible. |
