Disclosed herein is an atmospheric water generation system. The atmospheric water generation system may include a solar collector including a heat absorbing roof and an interior enclosure adjacent the heat absorbing roof. The heat absorbing roof may include a perforated dark panel that may be configured to allow ambient air into the interior enclosure. The system may further include a central tower extending upward from the solar collector such that heated air in the interior enclosure flows from the interior enclosure through the central tower creating an upward air flow stream in the central tower, a water-absorption unit disposed within the central tower and on a path of the air flow stream, in which the air flow stream may contact a water-absorbent liquid stream thereby generating a hydrated solution stream and a moisture-free air stream, and a membrane separation unit comprising a water-selective membrane that may receive the hydrated solution stream and generate a permeate stream including water and a retentate stream including water-absorbent liquid.

A method which allows the ejection of non-condensable gases, notably air, from a closed loop power generation process or heat pump system, is disclosed. A vessel in which a working fluid is absorbed or condensed can be separated from the power generation processes by valves. Residual gas comprising CO2, non-condensable gas such as air, water and alkaline materials including amines may be compressed by raising the liquid level in said vessel. The concurrent pressure increase leads to the selective absorption of CO2 by alkaline materials. In simpler embodiments, mainly air is removed from one- or two-component processes. Following the compression, non-condensable gas may be vented, optionally through a filter. The method is simple and economic as vacuum pumps may be omitted. The method is useful for any power generation and Rankine cycle, and particularly useful for the power generation process known as C3 or Carbon Carrier Cycle.

This disclosure provides water processing apparatuses, systems, and methods for recovering purified water and concentrated brine from wastewater. The water processing apparatuses, systems, and methods utilize ionomer membrane technology to separate water vapor from volatiles of a wastewater stream. The wastewater stream is evaporated into a gas stream including water vapor and volatiles of the wastewater stream in an evaporation container. The gas stream is delivered to a water separation module spatially separated from and fluidly coupled to the evaporation container. The water vapor of the gas stream is separated out in the water separation module while the volatiles are rejected. The water vapor can be collected into purified water while concentrated brine from the wastewater stream is left behind in the evaporation container.

In an example, a condenser apparatus to condense vapored fluid has a gas inlet, a mesh, a cooling element, and a gas outlet. The mesh is configured to carry a layer of condensed fluid. The cooling element is configured to cool the layer of condensed fluid. The mesh is configured to let pass through vapored fluid and to create bubbles including vapored fluid in the layer of condensed fluid.
