A process is provided for separating hydrophobic material from a mixture of hydrophobic and hydrophilic material using peptide-based amphiphilic organogelators.

Provided is an apparatus for controlling a seawater desalination plant. The apparatus includes: a dissolved air flotation device configured to provide treated water obtained by treating seawater according to a dissolved air flotation (DAF); an ultrafiltration device including a plurality of ultrafiltration units each having an ultrafiltration membrane, and configured to perform an ultrafiltration (UF) process of filtering impurities remaining in the treated water using the ultrafiltration membranes of the plurality of ultrafiltration units; a reverse osmosis device; an information collection unit; and a state treatment unit.

Systems and methods for desalinating a liquid are provided. A desalination system may include a main container and may be configured to provide at least one of an electric field or a magnetic field through the main container to control a distribution of ions in a liquid in the main container.

A system for generating electricity, heat, and desalinated water having a gas turbine system connected to a first electric generator, a waste heat recovery boiler (WHRB) system, a combined heat and power (CHP) generation system connected to a second electric generator, one or more solar powered energy systems, and a desalination system. The desalination system is connected to the CHP generation system and the WHRB system. The gas turbine system generates electricity and heat, the WHRB system is connected to and uses the exhaust of the gas turbine system to provide heat and steam power to the CHP generation system. The CHP generation system produces and provides electricity and heat to the desalination system, which produces product water, and at least one solar powered energy system provides thermal energy to one or more of the gas turbine system, the WHRB system, the CHP generation system, and the desalination system.

A method by which an environmental energy (e.g., wave energy) is harvested, converted into electrical power, and thereafter used to electrolyze seawater into hydrogen and chlorine gases. Those gases are recombined into hydrogen chloride from which is formed hydrochloric acid solution which is diluted and deposited at a depth sufficient to ensure its neutralization and sequestration for a significant period of time (e.g., for over a millennium). By removing chloride ions from a portion of the sea adjacent to its upper surface and depositing them into a portion of the sea more adjacent to its bottom, acidity is shifted from the surface to base of the sea, and the surface ocean is given a greater ability to absorb and buffer atmospheric carbon dioxide without a corresponding increase in acidity.

The present disclosure is directed to an electrodialytic stack with a concentrate stream that moves through a concentrate flow path bounded by a central ion exchange membrane and a first outer ion exchange membrane. A dilute stream moves through a dilute flow path bounded by the central ion exchange membrane and a second outer ion exchange membrane. A redox shuttle loop is separated from the concentrate and dilute streams by the first and second outer ion exchange membranes, respectively. The outer ion exchange membranes are a different type than the central ion exchange membrane. Electrodes are operable to apply a voltage across the stack. At least one collection of ion exchange materials is located in at least one of the flow paths. The ion exchange materials migrate ions between the central ion exchange membrane and at least one of the outer ion exchange membranes.

An adsorption structure unit prevents water leakage from an adsorption structure and improves the durability of the adsorption structure and the durability of the adsorption structure unit. An adsorption structure has a filter portion having a plurality of flow paths divided by a plurality of partition walls and a plugged portion shutting a feed water inflow or outflow end of the plurality of flow paths, a water-impermeable outer tube accommodating the filter portion, and a seal material blocking a gap between the filter portion and the outer tube in at least one end portion of the filter portion. An adsorption structure unit has the adsorption structure, a housing supplying feed water from one end of the adsorption structure, and discharging the feed water from the other end, and a ring member disposed between end portions on both sides of the outer tube and an inner surface of the housing.

Provided is a filtration method that includes a cleaning step and involves the use of a porous membrane, wherein the filtration method offers exceptional resistance to cleaning solutions (chemicals) (chemical liquid resistance) and exceptional filtration performance, and has a long service life. A filtration method includes the following steps: a filtration step in which a liquid to be processed that contains a material to be filtered is passed through a porous membrane configured from a resin having a three-dimensional mesh structure, and a filtrate is separated from the material to be filtered; and a cleaning step in which the porous membrane has a cleaning solution passed therethrough or is immersed in the cleaning solution so that the interior of the porous membrane is cleaned.

A DNA complex includes a carrier and DNA immobilized on the carrier. 80% or more by mass of the DNA is single-stranded DNA, the DNA has an average molecular weight of 500,000 or less, and the DNA content is more than 15% by mass and 50% or less by mass of the DNA complex. The carrier contains an inorganic material. The DNA complex has an average particle size of 10 μm or more.

A first stream of an aqueous solution flows through an upstream desalination or nanofiltration system. A second stream of the aqueous solution is mixed with the diluate output from the upstream desalination system or with the diluate or concentrate output from the upstream nanofiltration system with a flow ratio of the second stream of the aqueous solution to the feed stream of <0.47 or >0.63. A liquid composition flows into the concentrate channels of an electrically driven separation apparatus, while the feed stream flows into at least the diluate channels at a ratio of 0.3 to 0.81 to the flow of the liquid composition. An applied voltage selectively draws monovalent ions from the feed stream in the diluate channels through the monovalent-selective ion exchange membranes into the concentrate channels to produce a treated diluate having a sodium chloride ratio (SCR)<0.7.
