    Abstract: The present disclosure is directed at methods, systems and techniques for desalinating saltwater while generating electricity. A reverse electrodialysis (RED) stack is used to generate electricity, and the generated electricity is used to desalinate saltwater in an electrodialysis reversal (EDR) stack. As the RED stack relies on a concentration difference between two ionic fluids to generate electricity, a desalination plant that incorporates the RED and EDR stacks as described herein is referred to as a concentration difference energy plant. Brine discharge from a first desalination plant, such as a reverse osmosis plant, can be partially desalinated by the concentration difference energy plant, and the partially desalinated brine may optionally be returned to the first desalination plant for further desalination. This can result in several benefits. For example, the concentration difference energy plant can remove larger ionic species, which if not removed could cause scaling in the first desalination plant.

    Abstract translation: 本公开涉及在发电时对盐水进行海水淡化的方法，系统和技术。 使用反向电渗析（RED）堆电发电，并且所产生的电用于在电渗析反转（EDR）堆叠中对盐水进行脱盐。 由于RED堆栈依赖于两个离子流体之间的浓度差异来发电，所以将本文所述的结合RED和EDR堆的脱盐设备称为浓度差能量设备。 来自第一脱盐设备（例如反渗透设备）的盐水排放物可以通过浓度差能量设备部分脱盐，并且部分脱盐的盐水可以任选地返回到第一脱盐设备以进一步脱盐。 这可以带来好几个好处。 例如，浓度差能量植物可以去除较大的离子物质，如果不能除去，可能会在第一个脱盐植物中引起结垢。

    Abstract: The present disclosure describes a modular humidification-dehumidification (HDH) apparatus and system for concentrating a solution including a plurality of internal modules coupled to each other. The plurality of internal modules includes a humidification module and a dehumidification module in gas flow communication with the humidification module. The humidification module includes humidification media facilitating evaporation of liquid from the solution to gas as the solution passes through the humidification media thereby producing a concentrated solution and a humidified gas. The dehumidification module includes a condensing heat exchanger for condensing vapour from the humidified gas.

    Abstract: A hybrid electrochemical water softening desalination system softens water by both electrodialytical and non-electrodialytical means before desalinating the softened water in a primary desalination subsystem. The concentrate produced as byproduct from the desalination is provided to a concentrate channel of the electrodialysis device employed, and the electrodialysis device extracts multivalent ions from the water to the concentrate channel. In some embodiments the electrodialysis device provides softened water directly to the primary desalination subsystem. In other embodiments the electrodialysis device provides electrodialytically softened water to a non-electrodialytical softening subsystem for further softening, before the softened water is supplied to the primary desalination subsystem. The arrangement integrates the concentrate disposal line of the primary desalination subsystem with the functioning of the electrodialysis device.
