A method and system for in-basin neutralization is provided. More specifically, neutralizer is added to a basin in excess of an amount of neutralizer suitable to neutralize a treatment solution in a reservoir in fluid communication with the basin. A first portion of the treatment solution is added to the basin and is contacted with the first portion of the treatment solution to form a secondary solution. The first portion of the treatment solution is neutralized with the neutralizer. A first portion of the secondary solution is removed from the basin. A second portion of the treatment solution is added to the basin. The second portion of the treatment solution is contacted with a second portion of the secondary solution remaining the basin to form a tertiary solution. The second portion of the treatment solution is neutralized with neutralizer in the second portion of the secondary solution.

The present invention relates to single thread composite fibers comprising at least one binder and at least one active catalyst for the capture and degradation of chemical threats such as chemical warfare agents (CWA), biological warfare agents, and toxic industrial chemicals (TIC) and a method for producing the same. The invention fibers are applicable to the fields of protective garments, filtration materials, and decontamination materials.

An assembly containing a shelf-stable formulation for decontaminating skin exposed to toxic compounds located in a package formed with water and potassium bicarbonate in a first chamber; and a sponge, diacetylmonoxime (DAM), and polyethylene glycol (PEG) located in a second chamber. The package includes a barrier between the first chamber and the second chamber, with the barrier being configured to be rapidly removed when needed to enable the water and potassium bicarbonate to enter the second chamber. The package is made by placing the water and potassium bicarbonate in the first chamber of a package; mixing the DAM with PEG to form a DAM:PEG mixture; infusing the sponge with the DAM:PEG mixture to distribute DAM within the sponge; and placing the sponge, DAM and PEG in a second chamber of the package. Infusing the sponge includes solubilizing the DAM:PEG mixture in ethanol or another low boiling point solvent to form an ethanol-DAM-PEG solution and applying the ethanol-DAM-PEG solution evenly to the sponge. The ethanol is removed by applying heat and/or vacuum to the sponge.

In order to stabilize injection of water plasma, a vortex water flow generator forms a vortex water flow for passing arc discharge. The vortex water flow generator includes a cylindrical portion configured to form a vortex water flow along an inner circumference, a first middle partition and a second middle partition protruding from the inner circumference of the cylindrical portion. The first middle partition and the second middle partition respectively have an opening to include a center axis line position of the cylindrical portion. An opening of the second middle partition on the side of the positive electrode is larger than an opening of the first middle partition on the side of the negative electrode.
