DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components,
unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.
Fig. 1 shows a schematic diagram of an Apparatus 10 according to one embodiment of the present disclosure. The Apparatus 10 comprises an energy conversion means 16 placed within the Apparatus 10 and a reservoir 11 which is configured to store fluid. The reservoir
11 is selected from a group comprising a natural reservoir and an artificial reservoir. The reservoir 11 is fluidly connected with a primary conduit 12. In one embodiment both the reservoir 11 and the primary conduit 12 are substantially vertical and placed parallel to each other. Shape of the reservoir 11 and the primary conduit 12 can be but not limited to cylindrical shape. The Apparatus 10 further comprises an energy extraction means 14 which is placed within the fluid at a point proximal to the base of the reservoir 11 ahead of the junction of the reservoir 11 and the primary conduit 12. Axis of energy extraction means 14 is substantially vertical. The Apparatus 10 further comprises a fluid evacuation means 15 which is fluidly connected to the primary conduit 12 to evacuate the fluid from the primary conduit 12 and an energy conversion means 16 connected to the energy extraction means 14 such that the energy extracted using the energy extraction means 14 is converted to a usable form of energy. In one embodiment, the energy conversion means 16 is but not limited to an electric generator. In one embodiment the fluid evacuation means 15 is placed proximal to the top of the primary conduit 12 such that the fluid evacuation means 15 consumes least amount of energy for evacuating the fluid from the primary conduit 12. In one embodiment the fluid evacuation means 15 is but not limited to a pump. In one embodiment the energy extraction means 14 is but not limited to a turbine. Further, volume of the primary conduit 12 is less than volume of the reservoir 11 when the fluid is at same level in the primary conduit
12 and the reservoir 11. The reservoir 11 and the primary conduit 12 can be filled partially or completely with fluid. The Apparatus 10 in the disclosure uses the principle of gravitational force acting on the fluid in the reservoir 11 which creates potential energy. The potential energy increases by increase in height of the fluid column; with higher energy available towards the bottom of the reservoir 11 than at other locations in the reservoir 11. In one
embodiment as both the primary conduit 12, fluidly connected to the reservoir 11, and the energy extraction means 14 are placed proximal to the bottom of the reservoir 11, the energy available for the energy extraction means 14 is higher than at other locations. The hydrostatic equilibrium in the Apparatus 10 is disturbed by evacuating a predetermined quantity of fluid from the primary conduit 12. As the hydrostatic equilibrium is disturbed and a pressure gradient is generated, the fluid present in the reservoir 11 tends to flow from the reservoir 11 to the primary conduit 12. As the fluid flows from the reservoir 11, the fluid passes through the energy extraction means 14, thus actuating the energy extraction means 14. The actuation of the energy extraction means 14 rotates elements of the energy extraction means 14 in predetermined direction. Thus, potential energy present in the fluid is converted to kinetic energy at the location of the energy extraction means 14. The energy extracted by the energy extraction means 14 is converted into a usable form of energy using the energy conversion means 16 such as but not limited to an electric generator.
In one embodiment, the fluid evacuated from the primary conduit 12 is circulated back to the reservoir 11. Thus, the Apparatus 10 forms a closed circuit. Desired amount of energy, generated using the Apparatus 10, is also supplied to the fluid evacuation means 15 where the energy required by the fluid evacuation means 15 is less than the energy generated and thus the Apparatus 10 forms a self-sustained apparatus for power generation.
Fig. 2 shows a schematic diagram of an Apparatus 10 incorporated with a pressure based membrane filtration assembly 17 according to one embodiment of the present disclosure. The Apparatus 10 comprises an energy conversion means 16 placed within the Apparatus 10, a reservoir 11 which is configured to store fluid. The reservoir 11 is selected from a group comprising a natural reservoir and an artificial reservoir. The reservoir 11 is fluidly connected with a primary conduit 12. In one embodiment both the reservoir 11 and the primary conduit 12 are substantially vertical and placed parallel to each other. Shape of the reservoir 11 and the primary conduit 12 can be but not limited to cylindrical shape. The Apparatus 10 further comprises an energy extraction means 14 which is placed within the fluid at a point proximal to the base of the reservoir 11 ahead of the junction of the reservoir 11 and the primary conduit 12. Axis of energy extraction means 14 is substantially vertical. The Apparatus 10 further comprises a fluid evacuation means 15 which is fluidly connected to the primary conduit 12 to evacuate the fluid from the primary conduit 12 and an energy conversion means 16 connected to the energy extraction means 14 such that the energy extracted using the
energy extraction means 14 is converted to a usable form of energy. In one embodiment, the energy conversion means 16 is but not limited to an electric generator. In one embodiment the fluid evacuation means 15 is placed proximal to the top of the primary conduit 12 such that the fluid evacuation means 15 consumes least amount of energy for evacuating the fluid from the primary conduit 12. In one embodiment the fluid evacuation means 15 is but not limited to a pump. In one embodiment the energy extraction means 14 is but not limited to a turbine. Further, volume of the primary conduit 12 is less than volume of the reservoir 11 when the fluid is at same level in the primary conduit 12 and the reservoir 11. The reservoir 11 and the primary conduit 12 can be filled partially or completely with fluid. The Apparatus
10 in the disclosure uses the principle of gravitational force acting on the fluid in the reservoir
11 which creates potential energy. The potential energy increases by increase in height of the fluid column; with higher energy available towards the bottom of the reservoir 11 than at other locations in the reservoir 11. In one embodiment as both the primary conduit 12, fluidly connected to the reservoir 11, and the energy extraction means 14 are placed proximal to the bottom of the reservoir 11, the energy available for the energy extraction means 14 is higher than at other locations.

As the fluid flows from the reservoir 11, the fluid passes through the energy extraction means 14, thus actuating the energy extraction means 14. The actuation of the energy extraction means 14 rotates elements of the energy extraction means 14 in predetermined direction. Thus, potential energy present in the fluid is converted to kinetic energy at the location of the energy extraction means 14. The energy extracted by the energy extraction means 14 is converted into a usable form of energy using the energy conversion means 16 such as but not limited to an electric generator.
In one embodiment, the fluid evacuated from the primary conduit 12 is pumped outside the Apparatus 10 while the reservoir 11 is allowed to be refilled, from the external environment, through inlet 20 of the Apparatus 10 and thus the Apparatus 10 forms an open circuit. The external environment may be but not limited to industrial plants, oceans, rivers, lakes or any other source of fluid to be filtered.
In one embodiment, a pressure based membrane filtration assembly 17 is provided within the fluid at a point between the at least one reservoir 11 and the at least one primary conduit 12.
A secondary conduit 18 is fiuidly connected to the pressure based membrane filtration assembly 17 for carrying permeate. The permeate is fluid that is filtered out using the pressure based membrane filtration assembly 17. Further, a fluid evacuation means 15a is fiuidly connected to the secondary conduit 18 to evacuate permeate from the secondary conduit 18. Desired amount of energy, generated using the Apparatus 10, is also supplied to the fluid evacuation means 15 and 15a where the energy required by the fluid evacuation means 15 and 15a is equal or less than the energy generated and thus the apparatus 10 forms a self-sustained apparatus for fluid filtration or power generation and fluid filtration.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A
and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
