A freshwater harvesting assembly includes a micro-scale component selected from a polymer, a foam, and a membrane; a water-sorption material selected from metal-organic framework (MOF), nanosilica gel, and superabsorbent polymer; wherein the water-sorption material is incorporated within the micro-scale component to thereby provide a water-sorption-material-containing micro-scale component; and a housing carrying the water-sorption-material-containing micro-scale component.

The present disclosure is directed to devices, systems, and products for attracting, capturing and converting atmospheric water vapor into useful liquid water utilizing the thermal dynamic processes of deposition, phase change states and fusion.

A method may include providing a humidification-dehumidification unit proximate one or more abandoned wells, circulating a water feed through the one or more abandoned wells, using geothermal heat in the one or more abandoned wells to heat the water feed, directing the heated water feed to the humidification-dehumidification unit, and treating the heated water feed in the humidification-dehumidification unit to provide purified water.

Provided herein are water harvesting systems, as well as methods of making and using such systems, for capturing water from surrounding air using a design that reduces overall energy costs of the systems and improve water harvesting cycle efficiency. The systems and methods use sorbent materials, such as metal-organic frameworks, to adsorb water from the air. The systems and methods desorb this water in the form of water vapor, and the water vapor is condensed into liquid water and collected. The liquid water is suitable for use as drinking water.

A system for treating moisture in exhaust gas uses a cooling trap to remove the moisture contained in the exhaust gas. The system includes a tank that stores, as liquid water, the moisture flown out of the cooling trap and a water level measurement means that measures a water level in the tank. A pipe is connected to a drainage port for draining the water stored in the tank to outside and a valve is disposed in the pipe. Aa valve control means opens the valve to start drainage when the water level in the tank measured by the water level measurement means exceeds a first water level and closes the valve to stop the drainage when a second water level set lower than the first water level is reached. The second water level is provided at a position higher than the drainage port.

Disclosed is a cooling system comprising a cooling circuit with a deaeration device arranged in the cooling circuit for separation of air bubbles from coolant circulating therein. The deaeration device comprises a deaeration chamber having a coolant inlet connected to a feed pipe of the cooling circuit, a first coolant outlet connected to a coolant pump of the cooling circuit, and a second coolant outlet connected to an expansion tank via a static line. The deaeration chamber has a larger cross-sectional dimension than said feed pipe. The second coolant outlet is located in such a position in relation to the coolant inlet and the first coolant outlet that the coolant flow in the deaeration chamber between the coolant inlet and the first coolant outlet will move migrating air bubbles in the longitudinal direction of the deaeration chamber towards the second coolant outlet.

A desalination system that can comprise an inlet, an optional preheating stage, multiple evaporation chambers and optional demisters, product condensers, a waste outlet, one or more product outlets, a nested configuration that facilitates heat transfer and recovery and a control system. The control system can permit operation of the purification system continuously with minimal user intervention or cleaning. The desalination system can operate with any number of pre-treatment methods for descaling, and with degassing systems to eliminate or reduce hydrocarbons and dissolved gases. The system is capable of removing, from a contaminated water sample, a plurality of contaminant types including microbiological contaminants, radiological contaminants, metals, and salts.

An atmospheric water generator (AWG) may be used to extract water from ambient air. A compact screw compressor of the AWG may be used to compress refrigerant, a condenser of the AWG may be used to condense refrigerant, an expansion device, and an evaporator of the AWG may be used to transfer heat from ambient air to refrigerant, causing moisture in the air to condense. The condensed moisture may be collected in a water collection unit.

A distillation and desalination system can include a refrigeration unit, a distillation unit, and a vacuum source positioned in the refrigeration unit. The distillation unit may include a distillation chamber containing a saline liquid and a headspace above the saline liquid, the headspace comprising a gas. The vacuum source may include a first chamber defining a first chamber volume, where gas transport is permitted into and out of the first chamber and the first chamber is fluidically coupled to the headspace of the distillation unit, and a second chamber defining a second chamber volume, wherein the first chamber and the second chamber are fluidically isolated.

A multi-functional distiller for separating target compounds from a base material. The distiller has a basket, boiling tank, and sealable cap. The basket has at least one selectively sealable port for holding the base material. The boiling tank is adapted for containing a solvent, and the basket is attachable above the solvent. The sealable cap may be removeably attachable to the boiling tank to provide a sealed chamber. The sealable cap can be fitted with multiple condensers. One possible condenser is positionable exterior to the boiling tank and functions to condense vapors produced by the boiling tank. A second such condenser is an inverted condenser which is positionable interior to the tank so as to condense vapors produced by the boiling tank and cause the condensate to drip through the base material.
