The present invention provides a novel floating and renewable energy-powered desalination vessel, which also functions as a wind turbine generator and wave energy generator platform. With energy derived from the wind and waves, the vessel performs reverse osmosis within a vertically positioned cylindrical section extending below a buoyancy chamber. The cylindrical section contains reverse osmosis membranes located above a seawater screening and filtration system, which serve as ballast. The entire vessel and power systems are configured to have the center of mass below the center of buoyancy, forming a vertically stable floating structure with minimum pitch, roll, and wave heave in high sea states. The electric power generated is utilized internally to produce desalinated water or hydrogen from the desalinated water's electrolysis, power an onboard data center, or power delivery to a shoreside power grid. In addition to a wind turbine generator and a wave energy generator, a photovoltaic array or a marine current generator may be utilized to power these applications. Alternatively, the desalination vessel operates with the assistance of shore-based power provided by cable.

This invention relates to uses of graphene oxide, and in particular graphene oxide on a porous support, and a membrane comprising these materials. This invention also relates to methods of dehydration, which include vapour phase separation and pervaporation. Pervaporation is a method of separating mixtures of liquids using a membrane. Pervaporation consists of two basic steps: permeation of the permeate through the membrane and evaporation of the permeate from the other side of the membrane. Pervaporation is a mild which can be used to separate components which would not survive the comparatively harsh conditions needed for distillation (high temp, and/or low pressure).

The invention relates to a filter for filtering a liquid or a gas, with a pocket-shaped filter element which has a sleeve-shaped circumferential region, a closed head region and an open foot region, and with a frame element which has an annular base, in which the foot region of the filter element is accommodated, and at least one supporting strut which extends away from the base along the circumferential region of the filter element. An advantageous design of the filter is achieved by forming the head region of the filter element with a saddle shape, wherein two lateral tips are provided between which a channel-shaped recess is formed.

An object of the present invention is to provide a separation membrane module in which an end member is prevented from coming out even at the occurrence of a reverse pressure or the like. The invention relates to a separation membrane module which is equipped with a cylinder-shaped housing and a tubular separation membrane and which takes out a fluid which has permeated the tubular separation membrane. An end pipe is connected to one end portion of the tubular separation membrane; the end pipe is supported by a support plate which is disposed so as to traverse the housing; and an end plug is connected to the other end portion of the tubular separation membrane. The separation membrane module is further equipped with a coming-out preventive member.
