Problems solved by technology

[0013] The price of potable water is effectively equivalent to the price of crude oil in the Middle East, and would be more expensive than crude oil if it were uneconomical to build desalination plants to use seawater to convert to potable water

Embodiment Construction

[0037] Figure 1 shows a perspective view of a marine vessel with a valve fitted on the hull surface of the vessel.

[0038] The hull 20 of the ship is partly submerged under the sea surface 10 , and below the sea surface 10 a pretreatment filter valve 30 is fitted on the hull 20 of the ship.

[0039] Due to the movement of the ship in the water, the flow of seawater flows into the valve and directly into the stage of reverse osmosis group 40 installed inside the ship.

[0040] Figure 2 shows a perspective view of a marine vessel with a valve combined with an additional filter element and at least one membrane to filter seawater introduced through the valve to produce a product with reduced levels of impurities such as sodium chloride sea ​​water.

[0041] An improved embodiment is to install an additional filter after the seawater collection valve R1. The seawater flows into the membrane unit R2 to further filter the seawater, and a second processing component R3 is added to...

Abstract

The present invention relates to a method and apparatus for having a integrated fluid media filtration and membrane unit within the hull of a sea-bound vessel. The vessel's propulsion will drive the flow of seawater into the media filtration and membrane unit. Multiple stages of the passing of seawater via the membrane and / or a series of progressive membranes can be implemented to reduce the level of sodium chloride present in seawater to desirable specifications.

Description

technical field [0001] The invention relates to a method and a device for arranging an integrated fluid medium filter and membrane unit in the hull of a marine vessel. The propulsion of the vessel will drive seawater into the media filter and membrane unit. By means of a membrane and / or a set of cumulative membranes, it is possible to pass seawater through multiple stages to reduce the level of sodium chloride in the seawater to a desired specification. Background technique [0002] Various methods and processes currently exist that operate to utilize seawater as a source of desalination, thus creating new ways in which potable water can be treated and utilized. [0003] One such method is seawater reverse osmosis, whereby sodium chloride is removed from seawater and further treatment including ultraviolet radiation is used to kill any surviving bacteria or microorganisms to produce highly purified water, which is suitable for superior Potable water applications.
