Abstract:
Photovoltaic-powered reverse osmosis system. The system includes a photovoltaic panel for generating electricity and includes a heat exchanger in thermal contact with the photovoltaic panel. The salt-containing feed water is fed to a reverse osmosis unit to produce clean water therefrom. Fluid circuitry, including a pump, circulates the feed water through the heat exchanger to cool the photovoltaic panel and to heat the feed water. It also delivers the heated feed water to the reverse osmosis unit for desalination. Cooling the solar panel and heating the RO feed water increases the total amount of clean water produced. In a preferred embodiment, a thermal controller manages the temperatures of the photovoltaic panel and the feed water by controlling the flow of feed water through the fluid circuitry. The photovoltaic panel temperature is minimized and the temperature of the feed water is maximized subject to a constraint on maximum feed water temperature.

Abstract:
A method for producing clean water, in which water that is to be cleaned is caused to undergo membrane distillation by means of one or several units (1) comprising a first wall (2) that is impermeable to water and that has the form of a sheet, a membrane (3) through which water in the gaseous phase can pass, and through which water in fluid phase cannot pass, and a second wall (4) in the form of a sheet, which walls are located on different sides of and at a certain distance from the membrane (3), where water is led in between the first wall (2) and the membrane (3), and where the second wall is caused to be colder than the water. The invention is characterised in that the first wall (2) is caused to be an electrically heated sheet.

Abstract:
A self contained energy generating system that comprises a galvanic battery and a power distribution system. The energy generating system is used to purify water by using a reverse osmosis device that draws in a source of water and transfers electrolytes to the galvanic battery. Upon contact with the electrolyte, the galvanic battery produces energy by an oxidation-reduction reaction of the cathode and anode and transfers energy to the power distribution system, which in turn provides power to the osmosis device. Additionally, the system includes a hydrogen fuel cell to increase the amount of energy generated and a power storage device for storing excess energy generated. The system also includes a controller which is configured to regulate the overall operation of the system.
Abstract:
L'invention concerne un dispositif d'épuration d'eau de mer comprenant au moins une paire de modules de filtration (10a, 10b) d'eau de mer, notamment par osmose inverse, immergés dans le milieu marin et reliés l'un à l'autre par une transmission motorisée (12, 13, 19) adaptée pour déplacer les modules de filtration (10a, 10b) de chaque paire selon des mouvements alternatifs de plongée et de remontée dans le milieu marin. Chaque module de filtration (10a, 10b) comprend au moins une chambre haute pression associée à au moins une chambre basse pression. Les chambres basse pression des modules de filtration (10a, 10b) d'une même paire sont reliées l'une à l'autre par au moins un conduit (69) d'équilibrage des pressions régnant dans ces chambres basse pression.
