Definitions
- 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.
- sea-going vessels may make use of the seawater to convert into purified water for storage on-board these vessels, for export to far flung regions, while making the cost of such water within reach of many (this is due to the multiple consumption markets that is within reach of the sea-going vessel capable of desalinating sea-water into fresh water).
- 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.
- the present invention consists of a sea-going vessel, or any device capable of propulsion or floatation in areas where seawater or naturally occurring water is available.
- the said vessel will be constructed with suitable valves or openings capable of intake of seawater during the vessel's propulsion.
- the said vessel constructed with the said valves will also be capable of intake of seawater in a stationary position, having the said valve to be located within the level of seawater surrounding the said vessel.
- the main function of the valves incorporated into the sea vessel hull is primarily to accept seawater via pipes connected to the said valves for routing of the said seawater into a suitable seawater storage tank.
- valves will be operated by means of a suitable prime mover such as an electric motor, AC alternator, or powerplant to ensure that the valve can open or close the valve opening to control the rate of seawater intake.
- a suitable prime mover such as an electric motor, AC alternator, or powerplant to ensure that the valve can open or close the valve opening to control the rate of seawater intake.
- the construction of the valve may be constructed to be flush with the surface of the sea vessel hull, and may, optionally, include hardware that can prevent solid objects or other form of large particles to be filtered away from the vatve opening.
- the valve may be constructed to be protruding from either the hull surface, or surface area perpendicular to and/or along the length of the sea vessel.
- the present invention will also include the construction of filters within pipes connected to the said valves to remove any media (or particles) that may accompany the intake of seawater via the valve.
- the said pipes may also be fitted with membranes that can suitably remove a specific amount of sodium chloride and/or other impurities from the seawater being brought into via the said valves incorporated into the hull of the sea vessel.
- Figure 1 illustrates a perspective diagram of a sea vessel with a valve fitted onto the surface of its hull.
- Figure 2 illustrates a perspective diagram of a sea vessel with a valve combined with additional filters and at least 1 membrane to filter seawater incoming via the said valve to yield seawater with a reduced amount of impurities, such as sodium chloride.
- Figure 3 illustrates filtered seawater incoming from the valve fitted onto the hull of the sea vessel, being routed onto a assembly of devices capable of performing reverse osmosis to further purify the filtered seawater.
- Figure 4 illustrates a side view diagram of the major components and devices that are required for the processing and purification of seawater collected from valves constructed onto the hull surface of a sea vessel.
- Figure 5 illustrates the forward direction induced from the mechanical work imposed by a suitable powerplant unit installed within the sea vessel, enabling seawater to be fed into the valves constructed to accept the intake of seawater.
- Figure 6 illustrates how a suitable pump can be powered by auxiliary batteries charged by alternators connected to the sea vessel powerplant, enabling the said pump to continue feeding seawater into the pipes connected to the valves fitted onto the surface of the sea vessel hull, in the event whereby the sea vessel is stationary.
- Figure 7 illustrates the construction of a valve assembly incorporated with a suitable reverse osmosis membrane for processing of seawater (stage 1) in a typical reverse osmosis process.
- Figure 8 illustrates the construction of a valve assembly capable of routing seawater being treated by at least 1 reverse osmosis membrane, to a second valve and membrane assembly to further pass the said treated water to a second pass of another similar reverse osmosis membrane.
- Figure 1 illustrates a perspective diagram of a sea vessel with a valve fitted onto the surface of its huli.
- the vessel's hull 20 is partially submerged to the seawater level 10. Beneath the seawater level 10, a pre-treatment filter valve 30 is fitted to the vessel's hull 20.
- Figure 2 illustrates a perspective diagram of a sea vessel with a valve combined with additional filters and at least 1 membrane to filter seawater incoming via the said valve to yield seawater with a reduced amount of impurities, such as sodium chloride.
- An improved embodiment is to install additional filters after the seawater collection valve R1.
- the seawater is passed into a membrane unit R2 and to further filter the seawater a second stage of processing R3 is added to further desalinate the seawater.
- the purified water is stored into storage tanks R4 for storage and eventual consumption.
- Figure 3 illustrates filtered seawater incoming from the valve fitted onto the hull of the sea vessel, being routed onto a assembly of devices capable of performing reverse osmosis to further purify the filtered seawater
- the untreated seawater is channelled through a pre- treatment filter valve G1, which segregates the unwanted solid matters from the seawater.
- the said solid matters may be organic matter like fish or inorganic matters like man-made rubbish floating in the seawater.
- the filtration also prevents the clogging to occur in the membrane unit G3.
- Figure 4 illustrates a side view diagram of the major components and devices that are required for the processing and purification of seawater collected from valves constructed onto the hull surface of a sea vessel
- the seawater is first collected by the valve A-1 located at the front hull of the vessel.
- the system pump C-3 is required to pump the seawater into respective chambers for treatment. Treatment of seawater takes place at the membrane to 03 and ultra-violet irradiation unit B-2.
- the vessel and the treatment plant is powered by a power plant located in the vessel with auxiliary batteries to serve as backup D-4 as well as the kick-starting of the treatment process.
- a power plant located in the vessel with auxiliary batteries to serve as backup D-4 as well as the kick-starting of the treatment process.
- the treated water is pumped into storage tanks E-5.
- Figure 5 illustrates the forward direction induced from the mechanical work imposed by a suitable power plant unit installed within the sea vessel, enabling seawater to be fed into the valves constructed to accept the intake of seawater
- the seawater flows into the valve as shown by the arrow 3000 whereby the vessel is partially submerged in the seawater.
- the vessel power is powered by the power plant 1000 in order to propel itself across the sea.
- Figure 6 illustrates how a suitable pump can be powered by auxiliary batteries charged by alternators connected to the sea vessel powerplant, enabling the said pump to continue feeding seawater into the pipes connected to the valves fitted onto the surface of the sea vessel hull, in the event whereby the sea vessel is stationary
- the auxiliary batteries s4 When the vessel is stationary, the auxiliary batteries s4 will kick-start the pump s5 and pumped the seawater into the valve to carry on the treatment process.
- FIG 7 illustrates the construction of a valve assembly incorporated with a suitable reverse osmosis membrane for processing of seawater (stage 1) in a typical reverse osmosis process.
- Figure 8 illustrates the construction of a valve assembly capable of routing seawater being treated by at least 1 reverse osmosis membrane, to a second valve and membrane assembly to further pass the said treated water to a second pass of another similar reverse osmosis membrane.
