Abstract: Techniques are described herein for using a high-pressure reactor to separate clean water from dirty water without filtration and to extract and concentrate contaminants from dirty water for use as a fuel. In particular, techniques and systems are described for separating water from hydrocarbon contaminates, other BTU-laden compounds, and dissolved minerals, while also boiling water and condensing the resulting steam into distilled water. In addition, system in which the described techniques are performed can be used as a high-pressure pump for moving the separated hydrocarbon contaminates forward into other processes, such as a high-pressure reactor or incinerator.

Abstract: 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.

Abstract: A novel reverse osmosis or nanofiltration system (RO/NF) capable of detecting and responding to onset of fouling within the system utilizing uniquely configured membrane permeate flow path within the system which generates a time-sensitive data. Membrane performance data in real-time operating conditions is then utilized for rapid detection of membrane fouling, fouling rate, and cause of fouling, followed by controller-based system generated actions to stop, and recover from fouling or slow-down fouling, and, if required, to predict, plan, and schedule operator intervention steps to recover optimum system operating conditions. The end-result is a novel energy-efficient and fouling-managed advanced (machine learning) reverse osmosis system for brackish water desalination.

Abstract: A method and a system for saline-alkali water treatment by multi-membrane nanofiltration and photothermal conversion are provided. The method includes the following steps: separating Na+ contained water from saline-alkali water by multi-membrane nanofiltration; discharging the obtained Na+ contained water into an evaporation zone, and evaporating in grid-shaped pools step by step by sunlight. A membrane separation method is used with nanomembrane as the core to separate monovalent ion water from high-valent ion water, thus separating Na+ contained water from K+ contained water by NF, and finally extracting fresh water from Na+ contained water by a NF-RO component; meanwhile, a fertilizer preparation method can be used to handle high-valent ion water, K+ contained water and fresh water to obtain a liquid fertilizer or a soil conditioner; a KCl drug extraction method is used to treat K+ contained water in step S1 to obtain a potassium-supplementing drug stock solution.

Abstract: Disclosed herein is a method for recovering water from a salt solution. The method can include mixing the salt solution with a salting out solution that includes at least one enolizable ketone and at least one alcohol. The salting out solution can absorb the water from the salt solution and the water can be released using a regenerant solution. A base solution can also be added to fully regenerate the salting out solution so that it can be reused.
