Provided herein are integrated distillation apparatuses configured as stand-alone fully integrated systems having a reduced footprint. Integrated distillation apparatuses can have a rotary evaporator, a condenser, and an integrated refrigeration system or chiller, as well as an integrated water bath and vacuum pump, all of which can be integrated into a central frame and/or housing assembly. Integrated distillation apparatuses can be configured such that the rotary evaporator is movably attached to a frame structure and configured to be vertically translatable in position, whereas the condenser can be affixed to the structure by an arm extending from the structure and adjacent to the rotary evaporator, and wherein the refrigeration system can be in fluid communication with the condenser.

A dialysis system (e.g., a hemodialysis (HD) system) can be designed to operate in alternative environments, such as disaster relief settings or underdeveloped regions. The dialysis system can include a solar panel for generating electricity to power the dialysis machine and an atmospheric water generator for extracting water from ambient air. The extracted water can be used to generate dialysate and saline on-site. One or more of the components of the dialysis machine can be discrete components that are configured to facilitate fast shipping and simple on-site assembly (e.g., at a remote location). In some implementations, the discrete components may be configured to be attached to an existing dialysis system (e.g., a dialysis system designed for operation in a traditional environment) to permit the dialysis system to operate in an alternative environment.

A method of and system for recovering a dielectric fluid used for immersion cooling of electronic devices, the method including filtering the dielectric fluid to remove a first group of solid contaminants; distilling the filtered dielectric fluid in one or more distillation tanks to produce a vaporized dielectric fluid; separating the vaporized dielectric fluid from less volatile contaminants, such that the vaporized dielectric fluid is introduced as a condensate into a circulation tank; circulating the condensate by pumping the condensate from the circulation tank through one or more filters; filtering the circulating condensate through the filter(s) to remove a second group of contaminants; and returning the filtered condensate to the circulation tank.

An atmospheric water generator (AWG) may be used to extract water from ambient air. A compact screw compressor of the A WG may be used to compress refrigerant, a condenser of the A WG 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 cooling and desalination system includes a humidification-dehumidification (HDH) system and an ejector cooling cycle (ECC) system. The HDH system includes a heater for heating saline water, a humidifier for humidifying a carrier gas using the saline water, and a dehumidifier for dehumidifying the carrier gas to obtain desalinated water. The ECC system includes a generator for generating a primary flow of a refrigerant, an evaporator for cooling and providing a secondary flow of the refrigerant, an ejector for the primary flow and the secondary flow to pass through to obtain a super-heated stream, and a condenser. The heater and the generator are configured to connect to a heat source. The ECC system and the HDH system are connected at the condenser for heat exchange between the super-heated stream and the saline water to pre-heat the saline water.

A multimode system for cooling and desalination includes a humidification-dehumidification (HDH) system, an ejector cooling cycle (ECC) system and valves. The HDH system includes a heater, a humidifier and a dehumidifier. The ECC system includes a generator, an evaporator, an ejector and a condenser. The valves are configured to connect to inlets and outlets of the heater, the generator and a heat source so that by selectively opening and closing the valves, the heat source is connected to the heater while disconnected from the generator, or connected to the generator while disconnected from the heater, or connected to both the heater and the generator, or disconnected from both the heater and the generator. The ECC system and the HDH system are connected at the condenser for heat exchange.

The present disclosure relates to the technical field of wastewater treatment, and provides a wastewater treatment method and apparatus based on hydrate-based water vapor adsorption. The apparatus includes a wastewater evaporation zone, a hydrate formation zone, a hydrate decomposition zone, and a data acquisition and control system. Rising water vapor and condensed water formed during evaporation of wastewater at normal temperature react with a hydrate former on a cooling wall surface to form a hydrate, continuous evaporation of the wastewater is promoted, the hydrate is scraped off to a collecting zone below by a scraper after being formed, and the hydrate is decomposed into fresh water, thereby realizing wastewater treatment. The present disclosure provides a method for treating complex wastewater containing a plurality of pollutants, where water vapor is consumed to form the hydrate to promote wastewater evaporation, and water obtained from the decomposition does not contain pollutants theoretically.

Provided herein are water harvesting systems, as well as methods using such systems, for capturing water from surrounding air. The systems and methods use water capture materials to adsorb water from the air. For example, the water capture materials may be metal-organic-frameworks. 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.

In a system for perorming a multi-step process for selectively purifying various pharmacologically-relevant components of a source plant such as cannabis, an initial step of the process provides a low-temperature, robust process for dehydrating and decarboxylating the starting product—fresh raw cannabis—by means of a vacuum-assisted microwave distillation process. An important by-product of the dehydration/decarboxylation is a terpene-rich distillate. By doing the terpene capture under vacuum, distillation temperature may be kept low. The low distillation temperature maximizes yields of thermally-sensitive components such as terpenes and cannabinoids.
