TL;DR: In this paper, a process and device for Forward Osmosis (FO) Pressurized Device (FOPD) in general and one hydraulically coupled to a reverse osmosis(RO device for a FOPRO) was disclosed, which can separate salt from salt water to generate potable water from water with high salt content (such as sea water, urine, sweat, brackish water and the like).
Abstract: There is disclosed a process and device for Forward Osmosis (FO) Pressurized Device (FOPD) in general and one hydraulically coupled to a reverse osmosis (RO device for a FOPRO (Forward Osmosis Pressurized Reverse Osmosis). Specifically, there is disclosed a passive device (that is, not needed energy input) for using forward osmosis to generate significant hydraulic pressure that can be used to drive a reverse osmosis process, wherein the reverse osmosis process (not needed external energy to run pumps) can separate salt from salt water to generate potable water from water with high salt content (such as sea water, urine, sweat, brackish water and the like).

TL;DR: In this paper, a small-scale, commercially available marine RO desalinator with three different membrane modules on arsenic removal was tested with arsenic spiked local tap water, using As(III) and As(V) up to feed concentrations of 2400 μg/L.

TL;DR: In this paper, a reverse osmosis sub-sea desalination system is described, which includes a reverse Osmosis station configured to generate fresh water from salty water, a storage tank configured to store fresh water downstream of the reverse OSMosis station, and a pump fluidly connected to the reverse ORS station and the storage tank.
Abstract: A reverse osmosis sub-sea desalination system is disclosed. The reverse osmosis system may include a reverse osmosis station configured to generate fresh water from salty water, a storage tank configured to store fresh water downstream of the reverse osmosis station, and a pump fluidly connected to the reverse osmosis station and the storage tank. The reverse osmosis station, the storage tank, and the pump may be disposed at one or more depths beneath a surface of a body of salty wafer.

TL;DR: In this article, a method and apparatus for producing potable water by post-processing (post-treating) desalinated water obtained by desalination of seawater through distillation or reverse osmosis is presented.
Abstract: Provided are a method and apparatus for producing potable water by post-processing (post-treating) desalinated water obtained by desalination of seawater through distillation or reverse osmosis. The method includes a carbon dioxide absorption process of excessively supplying carbon dioxide into the desalinated water to absorb the carbon dioxide, a remineralization process of passing the desalinated water into which carbon dioxide is absorbed through a limestone filter in which limestone is filled to form calcium ions and bicarbonate ions, and a carbon dioxide exhaust process of supplying air into the desalinated water passed through the remineralization process to exhaust the carbon dioxide with the air to obtain the potable water. Therefore, a TDS concentration of the desalinated water obtained through a distillation method or a reverse osmosis method can be effectively increased to produce potable water, alkalinity of the potable water can be increased to prevent corrosion of a water distribution system, and the potable water can be produced with a simplified apparatus and low cost.

TL;DR: In this paper, a reverse osmosis module is lowered from a survival craft to a depth of about 130 fathoms at which depth the external pressure on the module is sufficient to cause substantially pure or at least potable water to permeate through the semi-permeable membrane of the reverse Osmosis modules into a collecting vessel.
Abstract: OF THE DISCLOSURE A method and apparatus for producing potable water from sea water which is particularly suitable for use in survival craft at sea. A reverse osmosis module is lowered from the survival craft to a depth of about 130 fathoms at which depth the external pressure on the module is sufficient to cause substantially pure or at least potable water to permeate through the semi-permeable membrane of the reverse osmosis module into a collecting vessel. A pressure relief valve is provided on the water collecting vessel to prevent excess pressure build-up during recovery and an outlet means is also provided to remove the potable water when the apparatus is received in the survival craft.
