Abstract: The present invention introduces a capillary distillation method comprising the following steps: heating wastewater, subsequently directing the heated wastewater to one end of a water-diversion fiber material. Through capillary action, the heated wastewater permeates the water-diversion fiber material, diffusing downward along microchannel pathways within the material. Upon reaching the surface of the water-diversion fiber material, the wastewater evaporates. Water vapor is then directed to a condensation module, where it undergoes condensation and collection, resulting in the production of fresh water.

Abstract: The present invention relates to a method for concentrating, with low energy, a solute-containing solution in a state of multiple-no osmotic pressure difference (M(multiple)−Δπ=0 RO), and, more specifically, to a method for concentrating, with low energy, an solute-containing solution intended to be concentrated, as a low pressure in a state of multiple-no osmotic pressure difference. The method for concentrating a solution containing a solute at a low pressure in a state of multiple-no osmotic pressure difference, of the present invention, consumes less energy, enables concentration to be performed until a saturated aqueous solution with a maximum solute concentration is obtained or the concentration of the solute becomes 100% even though an extraction solvent is not used, and does not require the use of an additional osmosis-inducing solution.

Abstract: Systems and methods for treating a raw wastewater feed stream using a low energy ejector, which works as a heat pump to increase the pressure and temperature of a two-phase distillate stream used, in part, to heat the raw wastewater feed stream. The systems and methods utilize heat from a liquid distillate stream and a concentrated liquid wastewater stream to pre-heat the raw wastewater feed stream and produce a liquid distillate product stream.

Abstract: A galvanic system for iron dissolution in an aquatic environment comprises an anode structure including one or more pieces of iron or iron alloy; a cathode structure including a buoyant component and a first metal layer coated on the buoyant component, the first metal layer having a higher potential than the one or more pieces of iron or iron alloy; one or more wires electrically connect the first metal layer of the cathode structure to the one or more pieces of iron or iron alloy of the anode structure, wherein the anode structure and a portion of the first metal layer are operably submerged in the aquatic environment. The anode structure may further include a rack holder having multiple slots for separately holding the one or more pieces of iron or iron alloy. The cathode structure may further include a noble metal layer coated on the first metal layer.

Abstract: Radiative cooling enabled passive freezing desalination processes are described. High salinity water can be desalinated via radiative cooling-driven freezing desalination. The passive freezing desalination processes can be a complementary method to solar desalination to enable 24-hour, year round passive thermal desalination.

Abstract: The invention provides a semipermeable composite membrane that reduces an environmental load, and a method of producing the semipermeable composite membrane. A semipermeable composite membrane 100 includes, on a porous support 102, a semipermeable membrane 104 containing a crosslinked polyamide 120 and a cellulose nanofiber 110. A method of producing the semipermeable composite membrane includes obtaining a mixed solution containing the cellulose nanofiber 110, water, and an amine component, and obtaining the semipermeable composite membrane 100 by making the mixed solution be in contact with the porous support 102, thereafter, causing a cross-linking reaction of the amine component in the mixed solution, with the amine component adhering to the porous support 102.
