A water purification system provides clean water for the consumption by livestock by using a continuously recirculating water loop. Optionally, a circulating pump moves the water within the water loop in a flow direction. A water supply inlet is fluidically connected to the water loop to provide additional water. A particle filter system (or systems) is fluidically connected in series and removes dissolved solids or particulates within the water. An ozone purification system and/or with the addition of other antimicrobial or purification agents is fluidically connected in parallel to a portion of the continuously recirculating feedback monitored and control water loop. The ozone purification system is disposed downstream of the particle filter system and RO (or similar) system in relation to the flow direction. A feeding station is connected in series with the continuously recirculating water loop disposed downstream of the ozone purification system in relation to the flow direction.

Provided is a separation membrane leaf and a spiral wound module and an apparatus including the same, the separation membrane leaf comprising a separator, a supply-side flow channel material, and a permeation-side flow channel material comprising a tricot, the tricot comprising an adhesive part, and at least a part of the adhesive part being a low density part of the tricot, compared to the rest, wherein the tricot comprises at least one wale, at least one course, and an intersection point at which the at least one wale and the at least one course intersect, and the average distance between two intersection points arranged in parallel in the direction in which the wale of the low-density part is arranged is at least 1.25 times the average distance between two intersection points arranged in parallel in the direction in which the wale of the part other than the low-density part is arranged.

The invention discloses a portable beverage vessel, comprising: a bottom portion; a wall extending from the bottom portion, wherein a upper portion of the wall forms an opening through which beverage can be poured into or out of the portable beverage vessel; a first container element; a second container element, wherein a cavity is formed between the first container element and the second container element; and a display device positioned in the cavity and having a display element for displaying information; wherein the first container element can be at least a part of the bottom portion and/or at least a part of the wall; wherein the second container element can be at least a part of the bottom portion and/or at least a part of the wall; and wherein the first container element and the second container element comprise at least one of the following: glass; ceramics; SiO.sub.2; wherein the first container element and the second container element are connected by at least one of welding, laser welding, infrared welding, infrared laser welding and welding by an infrared laser emitting pulses of a duration shorter than 1 psec.

This invention relates, generally, to the collection of water. More specifically, the invention relates to an atmospheric water generator, to a condensation arrangement for an atmospheric water generator, and to a process for extracting water from air. The generator disclosed herein comprises a coolant chilling unit, a condensation arrangement, and a water holding and/or filtration arrangement which cooperate to extract water from air and store and/or filter the same for use.

Molybdenum disulfide membranes for ionic and/or molecular filtration applications are provided. The membranes have high separation performance, including high water flux and high molecule and/or ion rejection, and do not need to be stored in a hydrated condition in order to enable their reuse. The membranes are based on stacked MoS.sub.2 sheets having small hydrophilic organic functional groups covalently bound thereto.

Managed ecosystems, methods for producing managed ecosystems and methods for using managed ecosystems for sequestering carbon dioxide are described herein. Produced water is obtained and purified to sustain a managed ecosystem with saline-tolerant vegetation. The managed ecosystem biologically sequesters carbon dioxide by photosynthetically absorbing carbon dioxide from the atmosphere and by decomposition into a layer of sediment on the ecosystem floor.

Compositions comprising an isolated peptide, which may for example optionally comprise a sequence selected from the group consisting of FDYDWY (SEQ ID NO: 2), SFSQNKSVHSFDYDWYNVSDQADLKN (SEQ ID NO: 3) or CSFSQNKSVHSFDYDWYNVSDQADLKNC (SEQ ID NO: 1), or any cyclized version thereof, and methods of using same, including for treatment of or prevention of formation of microbial biofilms and against adhesion of a cell to a surface.

A water desalination system includes a first set of ultrafiltration membranes, a second set of ultrafiltration membranes, a first backwashing system configured to treat at least one of the first set of ultrafiltration membranes or the second set of ultrafiltration membranes with brine generated by a reverse osmosis process, and a second backwashing system configured to treat at least one of the first set of ultrafiltration membranes or the second set of ultrafiltration membranes with one or more chemicals and reverse osmosis permeate water.

A method of increasing operational efficiency of a power plant includes determining an average rate of accumulation of scale-forming compounds in a cooling water source, directing water from the cooling water source having a first concentration of scale forming compounds through a treatment system to produce a treated water having a lower concentration of scale-forming components than the first concentration by operating the treatment system with operating parameters selected such that a rate of removal of the scale-forming components from the water in the treatment system is greater than the average rate of accumulation of the scale-forming components, directing the treated water back into the cooling water source, and circulating water including the treated water from the cooling water source through a cooling system of the power plant.

An osmotic food production system designed to produce fruits, vegetables, and freshwater from urine or saltwater. In some embodiments the osmotic food production system also produces oxygen. In some embodiments, the osmotic food production system is portable and capable of transporting on a vehicle capable of space travel. Embodiments of the present invention can be used to address the existing problems of food production, waste disposal/utilization, oxygen generation, and water conservation in an efficient way to allow for prolonged space travel or colonization of distant planets and moons.
