A system and method is disclosed for recovering reagents that are used in removing contaminants from a flue gas stream. The system and method includes contacting the flue gas stream with reagents such as ammonia and sulfuric acid to create an ammonium sulfate stream. The ammoniated sulfate stream is forwarded to an electrodialysis unit wherein the reagents are regenerated and recirculated back to the system.

A disposable, single-use wipe that can be used deodorize, disinfect, and/or sterilize an object. A wipe includes a flexible membrane or cloth-like element that may apply, distribute, and/or remove a treatment agent to, over, or from a surface of the object. A treatment agent, such as micron-, or nano-sized particles of a disinfectant or sterilant chemical, Ozone, negative ions, Hydroxyl radicals, or alcohol, etc., may be applied to the surface by the wipe or another applicator. An additional treatment agent (e.g., Triclosan, Chlorine dioxide, Hydroxyl radicals, etc.), may be associated with a wipe to enhance biocidal activity. The wipe may be used alone, in combination with a holder, or in combination with an applicator of energized treatment agent. An applicator and/or a holder may be used to energize one or more treatment agent to improve its efficacy.

The disclosure relates to recovering Li ions in a raw liquid into a recovery liquid at a high recovery speed. A lithium selective permeable membrane is constituted of a selective permeable membrane main body constituted of a lithium ion superconductor (ion conductor) having a particularly high ion conductivity and a Li adsorption layer formed as a thin layer on a raw liquid side (a first electrode) thereof. As a material constituting the selective permeable membrane main body, specifically, lanthanum lithium titanium oxide can be used. The Li adsorption layer is formed as a thin layer on a surface of the selective permeable membrane main body by carrying out a chemical treatment on the selective permeable membrane main body.

The present invention provides a gas generator and comprises an electrolytic cell and a water-blocking device. The electrolytic cell is used for electrolyzing electrolyzed water to generate a gas with hydrogen. The electrolytic cell has an outlet for outputting the gas with hydrogen. The water-blocking device is set on the outlet for preventing the electrolyzed water from flowing out when the electrolytic cell is tilted by a tilt angle. The gas pathway of the invention will be closed by the water-blocking device when the gas generator is toppled, thereby preventing the electrolyte-rich electrolyzed water from flowing out.
