Abstract: An electrochemical separation device includes a first electrode, a second electrode, and a cell stack including a plurality of sub-blocks each having alternating depleting compartments and concentrating compartments and each including frame and channel portions disposed between the first electrode and the second electrode. An internal seal formed of a first material is disposed between and in contact with the channel portions between adjacent sub-blocks in the cell stack and configured to prevent leakage between depleting compartments and concentrating compartments in the adjacent sub-blocks. An external seal formed of a second material having at least one material parameter different from the first material is disposed between and in contact with the frames of the adjacent sub-blocks in the cell stack and configured to prevent leakage from an internal volume of the electrochemical separation device to outside of the electrochemical separation device.

Abstract: Electrochemical treatment devices for treating water and methods of assembling the devices are provided. Disclosed masking and potting techniques allow separate feeds to be delivered to and/or collected from the depleting compartments and concentrating compartments.

Abstract: A membrane system isolates environment volume, contains hazards, enables detoxification, hazard removal, infrastructure restoration, and substance recovery. The flexible membrane system adjusts to advantageously shape its isolated volume and integrate existing infrastructure. Pollution and hazardous energy, including crude oil, toxic-gas, radioactive fallout, fire, and other hazards are isolated, while concurrently enabling access within the isolated volume. Pod encapsulated and readily deployed, the membrane system operates semi-autonomously, uses selective-filtering, specific gravity and substance differences to channel matter, mitigate hazards, protect the biosphere, preserve infrastructure and capture substances.
