The invention relates to a process for working up water containing 4,4′-dichlorodiphenyl sulfoxide and/or 4,4′-dichlorodiphenyl sulfone as impurities, comprising: (a) mixing the water containing 4,4′-dichlorodiphenyl sulfoxide and/or 4,4′-dichlorodiphenyl sulfone as impurities with an organic solvent in which 4,4′-dichlorodiphenyl sulfoxide and/or 4,4′-dichlorodiphenyl sulfone have a solubility of at least 0.5 wt % based on the amount of 4,4′-dichlorodiphenyl sulfoxide and/or 4, 4′-dichlorodiphenyl sulfone and organic solvent at 20° C., which forms a two-phase system with water and which can be stripped from water with a stripping gas and subsequently separating the obtained mixture into an aqueous phase and an organic phase, and (b) stripping the organic solvent from the aqueous phase with a stripping gas.

A hydrogen addition device adds hydrogen to a biocompatible solution of a liquid containing body formed by the biocompatible solution sealed in a molecular hydrogen permeable container. The hydrogen addition device is provided with a tank for housing the unopened liquid containing body, a hydrogen water generator for producing dissolved hydrogen water formed by water with hydrogen dissolved therein to supply to the tank, and a heating portion for heating the dissolved hydrogen water in the tank to warm the biocompatible solution of the liquid containing body.

The present invention provides stretchable laminates with a flat appearance on the visible surface. The laminates comprise a textile layer, a functional layer, and a plurality of elastic fibers. The plurality of elastic fibers are in a substantially parallel arrangement and the internal distance between adjacent fibers does not exceed the maximum fiber spacing, which depends on laminate thickness in a stretched state. Also provided are garments and footwear comprising the stretchable laminates and methods of producing the stretchable laminates.

A system for sanitizing water in a hot tub is described. The system includes a sanitizing chamber, separate from the hot tub, and sized to hold a small portion of the water from the hot tub. A first conduit for conveys water from the hot tub to the sanitizing chamber. A second conduit conveys water from the sanitizing chamber to the hot tub. A pump is provided that moves water from the hot tub, through the first conduit into the sanitizing chamber and from the sanitizing chamber, through the second conduit, back into the hot tub. A heater heats the water in the sanitizing chamber to a temperature and for a time sufficient to destroy or deactivate undesirable microorganisms.

A supercritical water oxidation vortex reactor has a reactor shell configured to contain a pressurized and heated material including water, a burner assembly configured to create a supercritical core region in the material in the reactor shell, the supercritical core region including water above its critical point, an injector assembly configured to inject into the enclosed volume a subcritical wash stream including water below its critical point and an aspirator arranged in the enclosed volume and configured to remove a processed flow including purified water from an upper portion of the supercritical core region. The supercritical water oxidation vortex reactor is configured with an upward helical flow to transfer precipitated ionic compounds out of the supercritical core region, through a transcritical intermediate region, and into the subcritical wash stream where they re-dissolve.

A system for treating and/or recycling gray water includes a first receiving tank for gray water, a second receiving tank for treated water and a fluidic treatment circuit between the first and second receiving tanks. The first receiving tank includes an element for oxygenating the water in the first receiving tank and a system adapted to deliver enzymes into the first receiving tank. The fluidic treatment circuit includes a filtration unit, a microfiltration unit including at least one microfilter, a disinfection unit and a membrane ultrafiltration unit.

A method of sanitizing liquid for use in a medical device, the method comprising the steps of providing a medical device defining a water circuit with a volume of liquid, sensing the temperature of the volume of liquid with a sensor, heating the volume of liquid from an initial temperature to exceed a threshold temperature, maintaining the volume of liquid above the threshold temperature, determining a time-temperature value for the volume of liquid periodically once the threshold temperature has been exceeded, calculating a cumulative time-temperature value and providing an output signal once the cumulative time-temperature value has reached a level indicative of a sanitizing dose. A medical device and a liquid sanitizer are also disclosed.
