摘要： 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.
摘要翻译：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。

摘要： The present disclosure is directed at a modular apparatus for a saltwater desalinating system, and a method for using same. The apparatus includes multiple internal modules that are compressively coupled to each other. Each of the internal modules includes a pair of rigid end plates located at opposing ends of the internal module, and a stack of membrane bounded compartments that are layered from one of the end plates to the other. The modular apparatus can be used in a membrane based desalination system, which includes concentration difference energy systems, electrodialysis reversal systems, and membrane distillation systems. The modular apparatus helps to mitigate problems such as leakage and buckling in such systems, and can be used to increase membrane packing density and, accordingly, desalination efficiency.

摘要： Described herein are a method and system for desalinating saltwater using concentration difference energy. A "five stream" dialytic stack is described that can be used to desalinate saltwater at a relatively high recovery ratio. The dialytic stack may include, for example, one or more drive cells having a paired concentrate and a diluent-c chamber in ionic communication with a product chamber that is adjacent to an anion and a cation discharge chamber each filled with diluent-p. The drive cell applies a drive voltage across the product chamber, and when the drive voltage exceeds a desalination voltage of the product chamber, the saltwater in the product chamber is desalinated. The diluent-p may be at a lower ionic concentration than the diluent-c, which may be at a lower concentration than the concentrate. The relatively high concentrations of the concentrate and the diluent-c facilitate a relatively high recovery ratio, while the relatively low concentration of the diluent-p facilitates a relatively low desalination voltage. The dialytic stack may accept brine discharged from a first desalination plant and may use this brine as a source of the concentrate, diluent-c, or diluent-p. Alternatively, the dialytic stack may accept the brine as saltwater to be desalinated, and may then output desalinated brine back to the first desalination plant for further desalination. Processing the brine in the dialytic stack may decrease its volume, decreasing costs associated with treating or otherwise disposing of the brine.
摘要翻译：本文描述了使用浓度差能量使盐水脱盐的方法和系统。描述了一种“五流”透析堆，可用于以相对高的回收率对盐水进行脱盐。透析堆可以包括例如一个或多个驱动单元，其具有与阴离子相邻的产物室离子连通的成对浓缩物和稀释剂c室，每个填充有稀释剂p的阳离子放电室。驱动单元在产品室上施加驱动电压，当驱动电压超过产品室的脱盐电压时，产品室中的盐水脱盐。稀释剂-p可以具有比稀释剂c更低的离子浓度，其可以具有比浓缩物更低的浓度。浓缩物和稀释剂c的相对高的浓度有助于相对高的回收率，而稀释剂-p的相对较低的浓度便于相对较低的脱盐电压。透析堆可以接收从第一个脱盐设备排出的盐水，并且可以使用这种盐水作为浓缩物，稀释剂c或稀释剂-p的来源。或者，透析堆可以接受盐水作为要脱盐的盐水，然后可以将脱盐盐水输出返回到第一脱盐设备以进一步脱盐。处理透析塔中的盐水会降低其体积，降低与处理或以其他方式处置盐水相关的成本。

摘要： A method and apparatus for desalinating saltwater using concentration difference energy is disclosed. In order to desalinate saltwater that is contained within a product chamber, a drive cell is used to generate a drive voltage. The product chamber has a desalination voltage such that when a sufficient voltage is applied to the product chamber, anions and cations migrate out of the product chamber, thereby desalinating the water. The sufficient voltage, which includes the drive voltage and which is equal to or greater than the desalination voltage, is applied to the product chamber, consequently effecting desalination. Beneficially, concentration difference energy can be generated using a concentrated solution, which can be generated using, for example, solar energy.

摘要： 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.
